There was a little turbulence taking off and landing but mostly it was too late for me to make my connecting flight to Greensboro. Everything else was excellent.

There was a little turbulence taking off and landing but mostly it was too late for me to make my connecting flight to Greensboro. Everything else was excellent.

The seats were very nice in premium economy. The service was good. The flight was slightly bumpy. Would have appreciated more updates from the pilots.

Airline tickets are not cheap. You expect reliable competent service. Thanks to canceled flights and botched transfers we arrived at our destination two days late. This is not acceptable

Over 2.5 hour maintenance delay on first morning flight with no acknowledgement, compensation or even gesture of good will. Aircraft had overnighted at airport so issue should have been addressed prior to boarding. Over 3.5 hours before first slow and deliberate beverage service.

Referencing ANA'S service to Japan and the return on UA, the pillow was awful, the crew was not very attentive, and the food was bizarre and tasted okay. Whoever's idea it was to make vegetable tempera in a steam capsule should probably revisit that. Since it was the vegetarian option, it was my only choice.

Crew were welcoming, accommodating and they worked hard to find places for all carry on.

Broken tray table. Erratic service. Premium economy is more economy than premium- other airlines treat PE much better. No lounge access.

Our flight from Nice to Newark ran an hour late, and the food was mediocre, but it was fine. The problem was that we were scheduled to have a 4.5-hour layover in Newark, but then our flight to RDU was almost four hours late, finally departing at almost 11:30 p.m. We understand that flight delays were caused by weather problems in the East. However, there were at least two times, when were told that we would begin boarding in just a few minutes, only to have the flight delayed another 1.0-1.5 hours. This meant that we would leave a restaurant or the United Club, go to the gate, only to learn that there would be another major delay. Poor planning and/or communication.

It was good, although we could not get our preferred seats, we did enjoy the whole experience from Costa Rica. I still don't understand why our luggage is not the first to come out at the band.

I love United was disappointed we had a two hour delay, however the Pilot did say safety first.

Flight was delayed 5 hours. Initial reason for delay was 'maintenance' - which makes sense. Then, the additional 2 hours continued to say it was maintenance - when I know EWR had a 2 hour delay. AA did not say that. Additionally, when boarding, there was only one agent at the counter for a long time - until another came to help. After boarding, we had to wait another 45 minutes due to 'no catering'. So while we waited for catering, AA continued to board additional passengers - which seemed odd - and raised questions about what really was going on. I sat in First Class. During the flight, the flight crew allowed a significant number of non-First Class passengers to use the front bathroom - which created a very crowded environment in First Class which was uncomfortable. This also delayed First Class passengers from using the bathroom. Overall, horrible experience.

Returned home with a blood clot from flight homes and the uncomfortable aircraft I was on.

Seat was VERY uncomfortable. Flight was delayed and then boarded slowly. The crew was super helpful with boarding and supporting maximizing the luggage in the overhead.

Absolutely terrible. Would never fly American again. 2 deplaned incidents and delayed by close to 24 hours. $12 meal voucher for first class passengers was an insult to the injury. Pathetic.

Delayed, no updates, had a rewards number but was not working

Newark airport grounded inbound flight and only announced when the flight was about to start taxing.

I'm not a valued flyer so I'm always in the last group to board...that sucks, always

My flight got delayed for almost 4hrs and then it thankfully went to only 2hrs. Then we were told that there were no space for carry on bags and I had to get it checked... well I counted at least 8 spaces that weren't used and I was one of the few left that actually had one. There was definitely enough space and either the crew can't count or just genuinely are so lazy they don't want to do their jobs correctly and make sure that there ACTUALLY is no space.

Boarding can be more efficiently done by having the back row passengers board first. This way, the other people do the have to wait for front row passengers to load their luggage in the overhead cabins. Food is simply pathetic for the price I paid. Cleanliness is simply poor; my seat was full of crumps.

My morning PHX to NY flight was canceled. Not a cloud in the sky. No wind. No weather across the country. My guess is they canceled the flight because they didn’t have enough people or a mechanical issue. Either way really bad. I checked it at midnight and the 830a flight was on time so I was very surprised when I woke up to see the flight canceled and I’ve been rebooked on a flight… An hour earlier than my originally scheduled one. Of course I missed this earlier flight because AA texted at 4 AM when I was sleeping. I was re routed to Miami, boarded a plane, sat in the heat for 40 minutes, then boarded because of mechanical issues and had to wait another hour before finally getting to New York Ironically, the 430 Phoenix to New York flight landed at the same time I did… I could’ve been sitting at the pool all day vs jumping through hoops. never ever will I again fly American Airlines. No offer of a free drink, maybe a few points on my advantage account nothing… As if nothing happened and they did not inconvenienced me at all. I’m so sick of the dumb crackers that they give us on these flights. It’s really like a budget Airlines these days. A far fall for s once mighty company.

Boarding was easy. Provided drinks and snacks. Good aircraft and staff

The comfortability was very good. Except, when entering the craft the the first steward never greeted us upon entering the airplane. He spoke too fast where his words were all jumbled and difficult to understand.

WiFi was not eorkig (again) And the plane was from 1990 with the screens which were.not touch and most didn’t even work and if lucky could tune in tv

Except for the 28 minute delay leaving and the earlier reschedule to a later takeoff time the flight was good.

My encounter with the entertainment services provided on board was moderate; the functionality of the Wi-Fi connection was either sluggish or nonoperational, while the display screens were antiquated and suffered from poor visibility. On the positive side, the cabin exuded a sense of expansiveness, and the crew exhibited amiable and accommodating behavior throughout the journey.

My experience with JetBlue was fantastic! The service was top-notch, the flight was smooth, and the staff were friendly and helpful. I would definitely fly with them again.

Great crew. Smooth flight that was on time. Boarding is a disaster as usual. Bought more room seat and was Grouo A. The flight was packed by the time I got on. TVs did not work as usual

There was only internet service for the last hour. Other than that is was a great flight. Good Crew and landed a head of time.

Best Thing flight took less time than programmed, quick entry and exit. Recommended!

No entertainment, no WiFi, not great seats. Crew was good.

Horrible experience with Avianca, they delayed their flight and when we arrived to NYC, AVIANCA took 1 hr y 30 mins to park the airplane and all passenger get off the plane, it made me lost all my trains to get back home and I came back to my place at 3 am instead of 12 am. On the top of that their plane seat are so uncomfortable and is not enough space and killed my legs and knees, Avianca used to be good when it was a Colombian company, now after Brasilian company bought them, their service quality is bad and their flights are delayed and oversold.

I handed in my suitcase in perfect condition at SAL Airport. And in MIA Airport I received it with one corner broken and the wheels bent.

I like the crew members they're very friendly. Clean plane. The flight was on time. I dont like the comfort my car seat its better that the plane seats. They charge for everything. This airline was very good. Now it's a low cost airline

Avianca is not what it used to be. So disappointing

why did we have to go through security mid flight

A few years ago long flights 6 hours or so used to have video screens and they offered ear phones. The food cart used to come and drinks. Now absolutely nothing. Avianca is as bad as Spirit Airlines. Avianca will now be my last choice when booking my next flight.

Same experience, very poor food, drinks or entertainment while flying. There are some products offered to buy but only using debit or credit cards . No friendly for seniors or people without cards.

Poor In food , poor in entertainment , passengers don’t get for free not even water

It’s very nice, the only thing is that we have to purchase food.

Old planes rude workers no tvs seats don’t go back and overpriced

A 630departure flight Delayed 6hours! They changed my gate, I moved to the new gate. Had our flight on the screen for 12noon departure. I go get above to eat, check screen again and the flight was gone, no notice no announcement, nothing!! They sent my bag on the flight I wasn’t on, got it back to me 3days later. Thank goodness they did refund my money but I will NEVER fly them again.

Plane and crew on board were fine. Everything else was terrible.

Disaster. They lied every step of the way. We ended up being delayed due to crew and then allegedly abandoned the flight because of a curfew at LGA. No rebooking to LGA at any reasonable time. No hotel. No meal vouchers. Had to sleep in the airport and fly to Newark instead. Will never fly Frontier again.

My first flight was delayed 5 hours. The 2nd flight was canceled til the next day and the never even tried to compensate for it. Worse I was delayed again on the flight the rebooked me on.

I guess you get what you pay for. The seats are very uncomfortable and very little space. The snacks were pricey.

Would be great if Frontier can Assign Seats together under one PNR

They cancelled the flight and did nothing. I should be compensated for my uber rides to and from airport. Not a good service by frontier or kayak.

food not having to pay for it, reclining seat would be nice, more leg room, HEAT!!!!!!!

Very easy with the app to board and staff skills

Flight was changed (according to Frontier, by Kayak) without my notification. And all flights were delayed by at least an hour and a half. Uncomfortable plane. Bad service. Will never fly Frontier again.
