Pros: "On time, nice stewardesses who kept after drinks, offered refills, good snack(maple cookie) pilot again commented. Comments on turbulence especially calming. Also like a little geography like what river we are over. Deveops personal relationship"
Cons: "It was a fine flight but let me talk about boarding in general. After your special groups seems like you should load back of plane first? Window seats first? Boarding is a series of hurry up and wait experiences. I do not like feeling like cattle waiting in gate ramp or walk then in aisles. Must be better way. Please don't let people bring on 3 personal items and carryon. Make them check carryon or?"

Cons: "delays were long, video sound is too loud for an evening flight. too many adds play on the screens and over the PA system"

Cons: "my checked luggage was delayed a day"

Cons: "There were no blankets"

Pros: "Agent was able to get us on an earlier flight. She was very helpful and friendly. 2 of us shared 3 seats in the emergency row."
Cons: "Pay entertainment. Can’t shut off screen. Cycles same ads. Super annoying! Seats are crammed. Service is as minimal as they can get away with. I prefer delta! Don’t fly United if I can help it."

Pros: "The plane was not cleaned prior to departure so the bathroom was disgusting. One of flight attendants cleaned it , probably not her job but appreciated. The staff was terrific with an exhausted group of passengers."
Cons: "This flight was more than two hours late. The updates were not shared at the gate and we were strung along about the departure time. If a person didn't have the app, little to no info was available."

Pros: "The flight crew was very helpful and very nice. I was traveling with my 7 month old daughter by myself and the crew made sure I was taken care of."
Cons: "When I got off the plane and was waiting for my stroller and car seat to be brought up from the cargo hold, I received the car seat first in good condition. My stroller, however, had the clip busted off that connects the car seat to the stroller and cannot be replaced. So my entire travel system is now unusable. I know this happened on my transfer from Houston to Denver because I had to use my stroller when I got off of my flight from West Palm Beach to Houston and the entire thing was in tact. This is extremely frustrating because this travel system is $450 and is now unusable. And what's even more frustrating is that these items have to be gate checked and are given "special handling" tags when they are checked. The clip that was busted off is a pretty substantial piece so my stroller had to have been handled extremely poorly in order for this clip to bust lose."

Pros: "Once again, United was exceptional in providing the utmost care and service for its passengers."
Cons: "No complaints."

Pros: "Nothing"
Cons: "Nothing"

Pros: "Nothing"
Cons: "6 hour delay. Sending the plane from Denver to salt lake and back to Denver before a 7:55am flight was supposed to take off . Having 1 person on the plane from Salt Lake to Denver. Forcing a full plane of Denver durango customers waiting for 6 hours"

Cons: "Limited overhead space"

Pros: "Busy & hectic with a very full flight, but staff was attentive & friendly."
Cons: "All fine"

Pros: "Suitcase arrived at the carrousel on time , much better than Houston."

Cons: "Bad communication between crew and guests . We sat on the runway for over an hour before them told us what was going on . The most rude and awful flight attendants I've ever had . Same thing with landing no communication as to why it took so long till the end , over all I'll prolly never fly United again and I would like a full refund ."

Pros: "The best part was relaxing at the United Club before the flight. I will try and book flights with United and go to the club especially when returning home."
Cons: "We volunteered to take a later flight if needed. It was a little chaotic, but the ground crew did an excellent job getting us on the flight."

Cons: "Flight was delayed due to maintenance issue (as usual) and the employeea didn't even try to accommodate with those that had a connecting flight. They were pretty much like oh well, just get a hotel for the night. I swear United hires the rudest people!"

Cons: "Two delays"

Pros: "Friendliness of the staff"
Cons: "Nothing"

Pros: "It was inexpensive"

Cons: "Twice on this trip, the plane was not at the gate, since it needed to be delivered.......In Houston, when it was delivered, the gate agent reported that the interior was too hot, they had to cool it down. Then, after we were all on, the crew arrived, saying they had just been assigned to our flight. Needless to say, the flight was over an hour late, many of us missed our connections and had to spend the night,"

Pros: "Boarding was smooth. Everything on time. Friendly people."
Cons: "Uncomfortable seats. They were a little cramped in the width, but unbelievably cramped to the person in front of me. Spirit has more room."

Pros: "nothing"

Cons: "The KAYAK APP sucks i selected annother date And time And missed the flight as a no show. I selected the date for next thursday And the APP moved it And booked it for the same day. impossible to take it was Erich And not the date i wanted. I reeboked it in UNITED direct payed 75 USD and fixed kayak mistake. Never use this sh...t again"

Cons: "Confirmation number N89G3L. Literally just look at what I had to go through to get from Denver to Liberia and back. In total; 3 cancellations, 9 delays and had to leave the plane after being boarded 3 times in a row at Houston. Unacceptable. I would like to get money back for this trip, as it took off two days of traveling and took us well over 48 hours of travel time within airports. Is there any way I can be put in contact with someone from United Airlines about this? Thank you."

Pros: "My flights were great. The staff were friendly and kept smiles on their faces. They did everything they could to ensure that all passengers were comfortable. The pilots were energetic and kept us informed of every detail regarding the plane and the flight"

Pros: "It was Dec 23rd the busiest travel day of the year. Check in was easy. Courteous help was available. Boarding was a bit slow, but it was a ful flight. We took off on time and landed early. The flight was smooth with helpful attendants."

Pros: "The crew was nice"
Cons: "United has decided it can squeeze another inch or two out of your legroom by making the padding on the seats superthin, which results in not only hard seating, but the tray table mechanism in the back of the seat in front of you projects out a few inches, effectively pinning you in place. The seats recline a total of about 3 inches, which is to say two versions of bolt upright. I spent the entire trip trying to find a non-painful position to wedge my body into, but I failed. I heard one of the crew say they hated the new seats. There was no food. The streaming entertainment system was out of order. This will be my last trip on United."

Pros: "On time departure"

Cons: "no snacks for free"

Pros: "Everything was fine."

Cons: "Lste. Hot in cabin."

Cons: "I actually threw up on the plane is was so bad."

Pros: "Easy check in"
Cons: "Fair was little high for this flight"

Pros: "simplicity."

Pros: "Everyone was so nice, from the sweet girl who checked our bags in Houston to all the flight attendants on the plane."
Cons: "The girl in Houston could've used some help"

Pros: "The initial ticket price. I was just needing a cheap flight to SLC from Houston to pick up my family and drive them back home. So for the price I didn't need any luggage and it was perfect and cheap."
Cons: "The lay over. The cost for a 12 oz can of soda is two dollars. The rude staff. The fact that my flight should of got there at 11:45 and instead it got there at 2:00 am."

Cons: "No beverage service throughout the flight, not even water. Although, they collected trash about 10 times."

Pros: "All good. 1 stars for food and entertainment cuz there was none, at least food only for purchase. Understandable though."

Pros: "I've flown Frontier before & you are a great airline."

Pros: "On time. Smooth flight. Friendly crew. Comfortable seat."

Pros: "I loved that the plane was new (at least it looked like it) and super clean and that the flight was ON TIME!"
Cons: "Don't bother paying extra for a seat. The crew does not enforce that everyone is sitting where they are supposed to. I paid extra for a seat, and someone was sitting there and refused to get up. I didn't want to make a scene, as I don't want to be on the news for trouble on an aircraft, but I would appreciate it if the crew would make sure people are sitting where they are supposed to if seating costs money."

Pros: "Efficient flight and crew"
Cons: "Extra 45.00 charged for laptop bag brought with me. The only piece of luggage or carry on. Rediculas"

Pros: "Everything was well run and ontime"

Pros: "After our long delay I was rewarded a $100.00 flying voucher to be used on a future frontier flight. That $100.00 was more than I had paid for my flight in the first place."
Cons: "Our flight had a continual delay. At first it was only supposed tonbe about 30 minutes, but it ended up being a 4-hour delay. The plane needed a new wheel but the part wasn't in hand so we had to wait for another plane to fly in the Part."

Pros: "Staff was very friendly and efficient."
Cons: "Food options were awful, especially for what they charge for food."

Pros: "Timeliness"
Cons: "Uncomfortable, charged for everything. Not the Frontier of old."

Cons: "Everything..I will not ever fly Frontier again. The cost to pick a seat, baggage, carry on's, snacks on the plane, and shitty customer service from flight attendants. I could have flown Delta non-stop AND have everything included. I will make sure tour spread the word. Awful customer service. Caused many people to miss connecting flights and made them pay for overnight hotel stays, missed work, etc. No sympathy or willingness to do right by the customer."

Pros: "Nothing"
Cons: "Charge you for every bag, screaming children on every flight, charge for snacks, drinks. Chairs don't recline. Medical emergency on two out of four flights"

Pros: "Not trying to be hurtful, but not much. The people sitting next to me were nice. The temperature was fine. Nice takeoff, flight, and landing. The seating in the terminal was comfortable."
Cons: "The boarding was completely disorganized. The crew unprofessional. I overheard one crew member say to another "What is it with these Denver weirdos?". Then they complained about work and passengers the rest of the trip. I was in the front row and they must've assumed I couldn't hear them. I could. I know you're trying to reduce fares and making it an more a la cart experience, but $2.99 for a can of soda? Having to avoid the pile of ice that was dumped by the flight crew into the bathroom sink when i washed my hands wasn't very pleasant. The chairs are still incredibly uncomfortable, even in my "stretch" seating assignment ($35 poorly spent on my part). This trip made me rethink the cost benefit of taking Frontier. Flying United or American may be worth the extra money. And that's coming from someone on a tight budget. I used to enjoy flying Frontier and love taking a plane in general. I surely didn't this time."

Pros: "We had a very simple flight down from Denver to Houston. We were going on a cruise after the holidays. The airline lost our luggage and then every single associate that we talked to was rude, unhelpful and seemed to make the situation worse. As we needed our luggage for the cruise I was on the phone for a good majority of our first day on vacation getting little, to no help. Finally I was able to get help from the service that actually delivers the luggage. 5 stars for them! When I spoke to someone on the phone after all of thos they agreed to refund part of my luggage fees but I would like to have them all refunded as I paid a lot of money to even gt the bag on the flight and I did not receive what I paid for. Overall it is doubtful that I will ever fly Frontier again, and I will NEVER Suggest them to my friends or family. Terrible experience to say the very least."

Pros: "It is so annoying that frontier is constantly trying to sell you something. Other airlines sell things drinks or food but they are discreet. It's like frontier staff are working in commission."

Cons: "The flight was great but confirming seats was quite complicated since I did not want to pay extra to prereserve seats. Your website is extremely misleading and dishonest as the option not to pay a supplement is written very small at the very bottom of the page and all of the seats have prices on them suggesting that it will cost extra to reserve them. The seats were full of crumbs when we boarded."

Cons: "When I arrived two hours early to my flight, it was the first time I heard it had been cancelled. Apparently, due to weather. They said the only time they could get me out would be three days from then or they could refund me. No, they refused to pay for another ticket. So, I had to spend $435 on a ticket for later in the day when I had spent $130. Then, I look to Denver's weather and its perfect for the day. I call my mom, she's outside without a jacket! Where is the weather pray tell Frontier. This is the third and last time I ever use Frontier. Frontier is the worst airline I have ever used."

Pros: "Absolutely nothing the flight never took off and I never mad it to my destination."
Cons: "Everything this is the worst flying experience I've ever had in my entire life I will never fly frontier again"

Pros: "Frontier is so cheap. Flight got cancelled and they didn't bother to text or email with alert. Said they could reschedule 5 days later. I'll never fly then again."
Cons: "Everything"

Cons: "They refused to be helpful in a situation that caused me to have to re-book my flight with another airline as well as book myself in a hotel for the night. The customer service wasn't helpful on the phone or in person. They even tried to quote to me multiple times how it was my fault that they left early."

Pros: "Flight attendants were nice."
Cons: "Flight was late, Boarding procedure was not efficient it would help if they seated by seat letter when I boarded I was in seat f by the window but the other two seats were already occupied and they had to get up to let me in this happened numerous times for everyone on the plan causing a long boarding time. Plane had some off issues I think with the fuel pumps or the hydraulics there was a really annoying sound for the entire flight. No wifi Not enough leg room"

Pros: "Nothing"
Cons: "Everything. Terrible since they got bought out. Used to be a great local airline but not anymore."

Cons: "seat was very uncomfortable"

Pros: "It finally got me to my destination."

Pros: "flights were on time, gates close together. They had IPA beer for sale."
Cons: "seating was the most cramped I've ever experienced. I needed to get a boarding pass at the airport and low and behold all three of their machines were down. That was a 15 minute wait, compared to the normal airlines with 15 machines it was completely avoidable. I was surprised to learn carry on bags cost $40-45, putting me $20 below the cost of a untied flight."

Cons: "Passenger in front of me was very obnoxious and smelled"

Pros: "Staff was good."
Cons: "No TSA precheck, no wifii, no in flight entertainment, Everything cost money from carry on to drinks and food."

Pros: "Frendly service"
Cons: "No peanuts? ?"

Cons: "Worst travel experience of my life"

Pros: "N/A Jose Sanchez 305-763-6132"
Cons: "N/A"

Pros: "Plane left on time"
Cons: "The seats are hard as a rock and they charge you an extra fee to actually have a seat. I wanted to stand the whole time rather than pay the fee but hat was not allowed. Your ticket price is not the real ticket price."

Cons: "Charged $45 for a carry on is BS! Didn't even get a glass of water. Won't be flying Frontier again. There are other choices!"

Pros: "Nothing felt "budget" about the flight. it was a great plane staffed with great employees. The spacious seat option really did feel spacious."
Cons: "Nothing."

Pros: "nothing"

Cons: "Rude"

Pros: "trip was bad"
Cons: "Turbulence was bad and no complimentary water"

Cons: "Still seemed cramped in the seats with not much leg room. Seats did not recline at all"

Pros: "Staff very friendly and helpful"
Cons: "Seats uncomfortable"

Cons: "Very forceful in trying to sell your credit card, over and over you kept trying to sell it. Just annoying."

Pros: "Flight good very basic plane like they don’t even have a pocket holder and the tray is minuscule. The chairs are pretty firm but not bad for my 2 hour flight."
Cons: "My baggage was damaged , found open with one of the contents upon top of luggage, found it after beltmstopped and couldn’t find mine, I asked about it and Spirit lady said it’s to the side"

Pros: "Good flight"

Cons: "The delay but it wasn't to long of a delay"

Pros: "I liked that the staff was very friendly and helpful"
Cons: "I dod not like that a price amount was added for everything extra"

Pros: "Got what paid for"

Pros: "ABSOLUTELY NOTHING!!!"
Cons: "Everything. Glee spirit one other time and completely regret it. Haven't flown with them in 4 years. I remember why now. Flight was originally cheaper but by the time you pay all of there fees to get on the plane you're not saving at all. And once on the plane everything costs a fortune so now you've spent even more. They are never on time in my experiences and don't feel the need to give the paying customers updates. After several hours of delays you get the pleasure of being absolutely crammed in their crappy aircraft. NEVER AGAIN!"

Pros: "Nothing"
Cons: "I arrived at the terminal three hours early, connecting from a non-Spirit flight from Central America. Spirit employees wouldn't check me in, saying they were too busy and I need to wait, but no worry, there's plenty of time. Asked again later and was told to check in online. Checked in online and was told (after the many upsell screens) that I couldn't print a boarding pass and needed to go to a Spirit counter. Went back to the Spirit gate and they said I hadn't checked in so they gave away my seat, and they didn't have another flight until tomorrow. Did I want it? Nope. Bought tickets on a real airline. Will never, ever travel with Spirit again."

Cons: "Online check in was great but after printing boarding pass at home still had to wait in long line to just check bag"

Pros: "Nothing bad, nothing outstanding either."
Cons: "With all the baggage fees and the hassle of having to go back and pay for bags online after purchasing tickets, I'll fly a major carrier next time. After crunching the numbers and inconvenience of it all, I didn't save anything by flying Spirit. You truly do get what you pay for...go cheap, get cheap."

Pros: "None"

Pros: "They shut the doors early I miss my flight they refused to give me a refund waste of money as usual"
Cons: "They shut the doors early I miss my flight they refused to give me a refund waste of money as usual"

Pros: "Not much"
Cons: "Cost of baggage Web site"

Pros: "i was sent a message with a change or"
Cons: "the charge you 100 dollars for luggage.....plus sits before I know i paid the company 500 dollars, so if you were looking to save go somewhere else"

Cons: "The seats are cramped and on the way back, they canceled all flights back to Houston, causing us to pay an extra $600 in order to get home to work on Monday."

Pros: "Ease and price, legroom was ample as well"
Cons: "I didn't like paying for my water"

Pros: "Pilots did an amazing job with category 3 landing."

Pros: "Nothing"
Cons: "Everything"

Pros: "The price"
Cons: "The information"

Pros: "Cheap fare."
Cons: "Fees for everything."

Pros: "Everything was as expected. I highly recommend springing for the big seats on Spirit flights!!! It was well worth it."
Cons: "One small bag for a weekend trip is fine, but the price for anything extra is crazy expensive!!!"

Cons: "I'm not that large of a person, but I had absolutely no room. Tried to read magazine , no room. I did not like the super small tray table."

Pros: "Short Flight Good communication from the pilot - could have waited 15 - 20 min before actually telling us that we were starting the decent"
Cons: "I felt like a sardine. Sat between two large men, and I was SMUSHED. No comfortable positions - thank goodness the flight was short. The bathrooms were disgusting on the flight."

Pros: "It's a plane. It was a short flight- all was fine. It was cheap, and I didn't need any baggage, so Spirit is the best airline for that. You can't beat the price. Booked the night before- about 16 hours before the flight."

Pros: "Great overall experience, great price"

Pros: "The flight left on time-boarding was a breeze-the crew was professional and friendly-and the flight landed early. Great job!"

Pros: "The crew was friendly."
Cons: "Both of our flights were delayed for two hours with no explanation. Other airlines didn't seem to be having the same problems. It is rediculous that they charge for bags and that they are the only airline with a 40 pound weight limit when all of the others are 50 pounds. They charge $10 just to print the boarding passes at the airport. All of this they claim saves you money on the fare, but with all of the nickel and diming that they do to you after you purchase the ticket, it is much more affordable to go with another airline. I will choose some one else to fly with next time."

Pros: "Nothing"
Cons: "I wasnt allowed on my plane when it wasnt leaving for 43 minutes after i had arrived there. I would have been there the RECOMMENDED hour and a half early if i hadnt run into heavy traffic. Unfortunately, I only had 43 minutes before the plane left denver and the crew told me that i was late and wouldnt even give me the opportunity to try and get to the aircraft before it left. Then they told me that i could pay almost double what i had origionally spent on the flight to wait 4 hours for the next one with a 6 hour layover for thr connecting flight. I had then asked if it was possible to be reimbursed, the guy at the counter started laughing and said no it was my fault i was late. I have never been treated with such disrespect before in my life. I just dont understand, because no where does it say that if you're not there 50 minutes prior to the flight that you forfeit your flight. 50 minutes, i was there 43 minutes prior. Now i wont be able to visit my family for another year because i used my vacation time for that aweful experience with spirit ovwr 7 minutes. Then when i called kayak to explain to them what happened, they told me there was nothing they could do over and over again. Absolutely no help from either party."

Cons: "We booked and it took 30 minutes to move because of the AC"

Pros: "Nothing except that the pilot didn't crash the plane."
Cons: "Everything"

Cons: "Flight kept being delayed and then it was cancelled."

Pros: "It was an absolute disaster coming into DIA due to weather, but the crew kept us updated on events and it was great to be informed of what was going on."

Cons: "Delayed flight, sat on Tarmac for 40 min.."

Pros: "Nothing!"
Cons: "They didn't let us know it was cancelled after 4 hours of waiting due to bad weather even though all the other flights were taking off."

Pros: "I like the cost for the flight and everyone was very nice."
Cons: "I did not like that there was a big delay in the departure of the fight, I did not get to my destination until very late; this caused me to miss several activities planned for my granddaughter's graduation. I would have liked for my bag to fly at a lower cost as well."

Pros: "I did not know what to expect flying first time on Spirit but was pleasantly surprised at the efficiency and kindness of the employees."
Cons: "I was not pleased to find that the weight for a bag was 40 lbs and was charged $25 on top of the $40 bag fee for an overweight bag. This must have been in the fine print for I did not see it and packed my bag to be less than 50 lbs. The seats have no leg room and I found them to be restrictive for my 5'2" frame. They do not recline due to the space "saving" efforts of the airline. If you are looking for "cheap" remember to add on all the fees charged for bags, select seats, beverages before comparing to other airlines."

Pros: "Cheap. Ramen noodles. My personal carry on fit."
Cons: "EVERYTHING ELSE SUCKED!!! I actually opted to drive home 1100 miles rather than fly back."

Pros: "The intial price of the ticket was good."
Cons: "The seating is a tight squeeze. The plane was also very dirty. I'm happy i brought some wipes so I could wipe off my tray before using it. The lady who I checked in my bag at the ticket counter was absolutely rude. She ruined my mood for the rest of the day. Also by the time I finished paying for my bad there and back I could of paid for a nicer flight. I know better for next time."

Pros: "Boarding was fast and easy"
Cons: "Flight was delayed as always and the lines were astronomical to check a bag and print a boarding pass. Something that costs way too much money to be such a hassle."
