My flight was delayed so bad i missed u it so i just said never mind

Seats could be more comfortable, food was plentiful and good.

It was great. All the crew were professional and nice.

My original flight was cancelled and that affected my trip and my plans and I got no compensation and customer service was hard to reach as well

Compared to our Lufthansa flight out, it was pretty poor. Check-in was a nightmare trying to figure out if it was Lufthansa or United, the Kayak link kept sending us to a dead link with United. Then figuring out which code was United was a mess - it took way too long. On the flight, the seats were uncomfortable, they were out of all wines but red when the flight started, then out of red after the first beverage. The flight attendant said they never get restocked before they turn around to the US, so it happens all the time. The food was so bad we threw it away. For a long flight, it was pretty terrible.

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

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.

the seat was not padded at all - uncomfortable after a 3 hour flight

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.

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.

Better seats, allow us to upgrade, terrible website, poor telephone service, better equipment

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 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

I got to the airport and the airline told me i did not have a flight. I never got a confirmation email yet I did get charged. Please refund my money asap

Was charged for ticket, unable to check in online, made the line to speak to someone at the counter but was told I did not show up in the system as having a ticket to fly - even though I have the email with confirmation and credit card was charged. I could not purchase another ticket at the counter, only online which was not working. Ended up buying a flight on another airline at the airport. Called customer service to claim the cost of the original ticket, was told I showed up in their system as having a ticket but did not check-in or show up to board the flight. Currently pending review for refund via their customer service team, they were very nice and helpful over the phone despite the many glitches.

Do not book with this airline. Flights delayed over 3 hours and no explanation. They keep changing your itinerary every hour.

Awful. Not water, or chargers or space under the seats, the plane was very old and poor maintenance, seats really dirty, sticky, seats pockets with wires pinching your knees. Connection with no announcements, plane departed 1.30 hour earlier for an extra stop to refueling in Trinidad & Tobago. Even that we had a 3 hrs delay, seated in the plane in the runway.

Really bad. Uncommunicated stop in Trinidad & Tobago for refueling. Extra stop added 3 hours of discomfort without allowing off the seat. Not even water, or chargers or boarding groups.

Staff were unfriendly and rude. Was stuck on runway for 2 hours after arrival in Boston.

Horrible service. No communication from the crew as to why a 6 hour delay then cancellation

We waited in an overcrowded bus for over a half hour. It was uncomfortable. It would have been better to have waited in the terminal in a line

The food for sale on board has opportunity for improvement.

The Arajet person who greeted us initially was unhelpful & rude about the mandatory migration form which has to be completed digitally but the systems don’t work properly. The boarding gate was changed twice and initial boarding was delayed. Once on board we we had to wait an hour and a half before take off. It was hot and there was very little room for tall-ish people to fit their knees in. The crew were pleasant but working in a poor situation. The plane was delayed because we were waiting for people from a delayed interconnecting flight. Arajet must have known that before we were asked to board. Better information, decisions & communication were needed.
