Airline reviews
Pros: "Seats are comfortable, main reason I like this airline. Crew was nice."
Cons: "The screens on the back of the seats are showing their age and the controls on the armrests are causing your neighbor to change your channel or the brightness of the screen. Letting everyone stream content to their own devices would probably be a better option, with safe charging available."

Cons: "The screens on the back of the seats are showing their age and the controls on the armrests are causing your neighbor to change your channel or the brightness of the screen. Letting everyone stream content to their own devices would probably be a better option, with safe charging available."
Pros: "The crew was good, and they tried to make up for the delay with a gift certificate"
Cons: "More than three hours of delay because there was no crew assigned to that flight"
Cons: "Everything could have been better. Flight delayed 3 hours due to JetBlue schedule mismanagement. No consideration for elderly when we had to change gates across airport. Poor communication on flight updates. And then as a perk to make up for delays, tried to sell us a credit card. Just Awful."
Pros: "The crew was very friendly and helpful."
Cons: "The TV monitor was very small and the picture was pretty poor."
Cons: "Left very late because of delayed inbound flight and need for deicing."
Cons: "So first thing before takeoff one flight attendant told someone to turn there music down because it could be heard outside of the headphones, but then proceeded to talk extremely loud throughout the entire flight to the other attendants. It was a 6am flight and mostly everyone was trying to sleep, but she was so loud that I gave up after trying to. If you tell someone else to be quiet because of sleeping passengers, I recommend you follow your own advice."
Pros: "I appreciate that they let families with strollers board after Group A, there seems to be more space than the major carriers, and the snacks are good!"
Cons: "My Satellite XM radio didn’t seem to be working."
Cons: "No TV no sound . Was suppose to get $15.00 voucher for further travel still has not got the email regarding it"
Pros: "crew was supportive. wifi in the flight"
Cons: "the wait time and the boarding, off boarding of the flight. No electricity in the aircraft."

Cons: "Nothing"
Cons: "So professional during this pandemic. I felt safe the whole time. Slept like a baby, the flight was so smooth."
Pros: "Nothing, the flight was canceled without a refund. I highly recommend canceling all business with kiwi in the future."
Cons: "My flight could have occurred or I could have been refunded."
Cons: "We arrived around 39 minutes early and the whole process was very smooth"
Cons: "Really felt happy on time touch down nice journey with delta"

Cons: "Good company, have the very good attendants"
Pros: "The flight attendants were excellent, pleasant, and professional."
Cons: "The video system went down for a period of time."
Pros: "The flight attendant (age gentleman) with the quite sense of humor, and converse with a measure of ease. A role model for others, a nice aptitude than one can learn from."
Cons: "Just keep up the good work and always work towards self development. Treat others the way you would like to be treated, with respect."
Pros: "Delta refused to let us reserve a bassinet seat, and kept telling us to ask them later. They ultimately were not able to to provide one. They were the least accommodating of all the airlines we have asked."
Cons: "Better customer service."
Pros: "I liked that is was a short flight"
Cons: "Plan was old. Seats not comfortable. Plane not clean. Flight attendants not attentive. A lady stored her carry-on on the floor in front of her and she was in the emergency row! Attendant walked by before takeoff and said nothing! Really?!"

Crew made sure we had space since it was not a full flight. I slept the entire ride.

Flight was delayed by one hour, then another 1/2 hour then cancelled and changed till the next day. We were not allowed to get our luggage & put up in a dirty hotel. I had cockroaches in the bathroom. When I finally arrived home…i noticed the airline had damaged the zipper on my suitcase. An awful awful trip thanks to American Airlines.

I left my phone in seat 6C or B where I sat with my husband. The lady with the oxygen tank needed help coming back from the bathroom as we were ready to land. We stopped the movie we were watching on my phone to help her and I guess I forgot it. Please, please return my phone. Samsung note galaxy 20 ultra. It is on airplane mode. Thanks so much

It was quick, plane was loaded and the service on board was ok

Pros: "The seat was comfortable for a change must be a different plane"
Cons: "Terrible logistics. Stuck on tarmac because they couldn’t clear the previous plane out of the gate. Fellow passengers missed their connecting flights."
Cons: "Canceled flight caused me to remain in a hotel for another day. Confusing check in. No one to help. Machines broken. Unable to disembark from the plane. Bad logistics all the way around."
Pros: "Everything was great."
Cons: "I can’t believe I’m saying this but I don’t think anything else could have been improved"
Cons: "Even in first class the my treat you like cattle, asked for water 3 times and it came 30 minutes later with an attitude, like she was doing me a favor. The seats are a joke for first class, literally the cheapest trim configuration an airline could purchase."
Cons: "I wasn't able to board with bags so I had to change flight I paid class upgrade and never received refund"

For each flight from Key West to Fort Lauderdale to Newark to Buffalo there were at least three delays at each leg of our trip. We were due to arrive home @11:37 but finally arrived @2:25 AM costing us an extra day at the car park. Seats are uncomfortable resulting in need to seek chiropractic care for backache. Upon deplaning my husband discovered someone had taken his clearly identified carryon from the overhead bin. I will not plan on flying again soon and not on United.

Cons: "The internet connection was terrible i was not able to see anything that was being offered"
Pros: "Very comfortable B777-300 got me to catch some much-needed sleep on my flight, even with a lot of people on-board!"
Pros: "Flight attendants were absolutely amazing!!!!! They made the trip very enjoyable!"
Cons: "Food!"
Pros: "Friendly service"
Cons: "Cramped seating in basic economy, the upgrade seating wasn’t much better"
Cons: "Very cold but that’s better than very hot. Wore my coat and your blanket. Seat bottom was very uncomfortable but I sat on the pillow you provided and that solved that."
Pros: "The cabin was actually warm & toasty...used to it being chilly. Knocked everyone out for the flight. Staff was friendly & professional"
Cons: "It may have been a little too warm."
Pros: "Unavoidable delays at Denver set this crew back an hour, but the gate agent tagged everyone's carry-on's to try and expedite or loading. David, the steward, was also pleasant and hustling to help people get on and off at Denver."
Cons: "Flight into MLI earlier in the week had WiFi, this one did not"
Cons: "My seatmates and I were frozen for the whole flight, especially our feet - even with socks on."
Pros: "Flight attendant was great at least and despite seatbelt light being on whole flight, attendants did pass out those struppelwaffle things which I really do enjoy. Offered complimentary checked baggage to destination for people to use for their carry-on bag."
Cons: "Flight was delayed without a reason given. Plane appeared poorly maintained on inside, with loose interior border panels that would shake and make noise during turbulence."
Pros: "Cheapest flight but your interface does not show all the up charges for basics like seat selection or a CARRY ON. If you book spirit you see these options"
Cons: "Be upfront abput all the upcharges and let people select what they want in the checkout process vs finding out at the airport. no on travels without at least a purse and they charge for that. Spirit does the same but you know that during checkout. Had no idea frontier did this with your interface"
Pros: "It was a quick flight."
Cons: "The crew was obnoxious. They spent the whole time talking about work loudly, sometimes rude, and laughing hysterically. It was hard to rest."
Pros: "The flight was ok, nothing outstanding. Ordinary uneventful flight."
Cons: "Lots of extra costs for baggage, seats, drinks and snacks, not experienced with other airlines. One of the hardest landings I’ve ever experienced. Perfect weather and no wind to speak of so not sure what happened there."
Pros: "The flight attendants were pretty nice and attentive. The captain was good at keeping the passengers updated."
Cons: "The 2 hour delay was not fun while we sat waiting on the airplane. I realize this is not the crew’s fault."
Pros: "The ground crew was rude, the desk people were even less helpful and acted like I was a burden to them by asking qurstions"
Cons: "Frontier could have sucked less"
Pros: "The crew was great. The flight was smooth and comfortable. I paid $25 extra for extra legroom and closer to the front... and an aisle seat. It was totally worth it."
Cons: "The flight was delayed 2 plus hours."
Pros: "Fairly comfortable seating"
Cons: "It would be nice to have complimentary coffee. $3.00 for 6oz of coffee is a bit much,"
Pros: "Crew was super friendly."
Cons: "It would be nice to offer non alcoholic beverages for free."
Pros: "I didnt like anything"
Cons: "No complimentary drinks had to pay 70$ for one carry on bag rude customer service"
Pros: "The crew was very nice"
Cons: "It was difficult hearing when the captain was giving announcements."
