Most aspects were good however if they assign boarding zones they ought to enforce them or why bother? My luggage from SAN-JFK-MAD was lost in NY so I without my main bag for two days upon arrival in Spain. They were helpful in tracking it and eventually delivered it to my hotel. The flub was because of a delay upon arrival in NYC. I had booked 2 1/2 hours between flights but we had to hold on the taxiway for an hour after landing while waiting for a clear gate which likely caused the baggage error.

Excellent flight, the planes were newer, they did a nice job with boarding, great service overall.

It would be nice if was given wires ear buds. Overall was a good experience was able to sleep on the plane

737-800 in first class was pretty dumpy. Seat had an uncomfortable angle, storage under the seat was blocked so even my very modest backpack didn't fit, power outlet was flaky. Weird tiny seat pockets that couldn't hold a gallon ziploc bag, emesis bag missing, etc. etc. No in-flight service due to turbulence. Crew was excellent, boarding was smooth despite a full flight.

Delta flight was on time, seats were comfortable, and crew was nice.

Bathrooms dirty sinks clogged. No one seemed to clean them. Plane very old

Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

It was terrible, if they ran flights on time it would make a big difference.

Delta seems to be improving in many areas, except they are super bad with the food available. Bring back normal food service on long flights.

The chair cushions may need an upgrade. I have been noticing they are so worn out, thin so you’d sit in a dip 😄. Other than that, all was an enjoyable trip. Thanks AA!

Cramped seats. FAA should make airlines have more legroom, for even short people complain

Flight was full, and would have preferred an aisle seat, but due to getting a late ticket ,the seat I had was adequate. The flight crew were very help full and hard working. Food and drink were excellent for the 11hr flight. Overall I was pleased with flight, and would recommend British Airways again.

Eventless. It was a good flight and good crew. Can’t complaint.

Very helpful ground crew after an earlier flight delay and being rebooked on a different flight.

British Airways staff are very polite and willing to help.

The plane was late and then sat on the runway for almost 45 minutes before taking off.

We kept being told that the flight was full and that all overhead compartments were full and therefore had to check in our hand luggage. We were some of the last people to board and noticed that there was still sufficient space in the overhead compartments. We were obliged to check in hand luggage when there was space and so had to wait at luggage retrieval which took a while to then noticed damage to our luggage - not a great experience!

Worst seats I’ve ever had !!! The seats were very narrow and uncomfortable and misaligned with the seats in front of mine leading to bottom of the seat in front of mine pressing on my legs for 15.5 hours !

This was an overnight flight. There was no meal service in first class, just a simple snack basket was offered along with beverages. There should have been some type of continental breakfast prior to arrival in PHL. As an Executive Platinum American Airlines Advantage member, I received no name recognition from the first class flight attendant. When disembarking at PHL, the flight attendants were more interested in their cell phones than saying "thank you" to the passengers as they disembarked.

The boarding process was ridiculous. The boarded groups into a walkway just before the aerobridge (about 20 mins late), whilst we watch the crew stroll casually onto the plane, running late. And then they made us line up on then aerobridge with no aircon for 10 minutes before we boarded. Staff are just as ghetto as the customers. Wouldn’t fly again

They closed the gate over 25 minutes before departure and I didn’t get to board.

No empathy for my situation, arriving at the check-in counter 5 minutes after the deadline to deposit baggage due to a very delayed incoming intercontinental flight. The attendant simply stared past my shoulder and picked up the microphone to announce a "reminder that all passengers must arrive at least one hour before the flight" before speaking to the passenger behind me. I understand that there are rules above deadlines but at least show some damn empathy. It was Christmas morning and I'd been travelling for 20 hours for goodness sake!

They no longer offer anything free to eat or drink, everything is sold, not even a bottle of water is offered for free.

I paid for Viva play and most of the time didn’t work and also I order some drinks and the price was to expensive.

The terminal and gate was never the right one announced in the Viva App, neither in screens, moved from one terminal to another

The smart/express line to check in was a mess, employees not doing the process smooth and quick, using their mobile phones, talking to their coworkers

My flight was changed 4 tienes , delaying my arrival lore than 5 hours

Everything was okay, but boarding begins late and when I was returning there was a gate change. The app never showed the change.

Flights were delayed both ways, with no communication provided by the boarding desk. Delay time kept changing and the boarding process is a pain, as it is so disorganized. Would not recommend.

Confusion over extra fees. Held up on ramp during boarding. Thin seat cushion. Minimal leg room.

The check-in is either at a kiosk that didn’t allow me to check-in because my middle name was not on the reservation or at an agent that cost $15.

Better communication about delayed flight. I am thankful for a small credit for late flight.

Liked on time, rear entry and exit from plane Dislike the use of duct tape to repair seat rests

They don’t give anything for free you have to pay for everything which it’s expected but at least give out water and a snack as a courtesy for flying with them.

The worst. Kayak sent notification at 2am and 10am regarding the delay. Then sends a notification an hour before original depart time that it will depart on time. I had to wait 8 hours at the airport. My family had to pay for lodging in Guadalajara where I was landing for pick up.

They were only able to give me a seat and not my travel companion, she had to fly on a different airline. unacceptable

My experience was good. But it seems that every time I go on Volaris the plane is always full, not sure if because the price is cheaper. And the flight attendants kept hitting my shoulder every time they walked by the aisle with their food cart. I’m 6’4” so I barely fit in the seat next to the aisle. Plus the seat was defective. I had a hard time raising the lever where I rest my left arm. I tried calling the flight attendant 3 times if she could assist me but she was too busy talking in the back with her fellow flight attendants. Finally after 20 mins she looked my way and she too struggled to fix the problem but she finally raised it so I could get out of my seat.

Stood inside the plane for more than an hour before take off

I never got an email for checking in for my flight back to Los Angeles so I got to airport extra early to sort it. they changed the gate, and so I had to run to the other end of the airport. Their app is wonky. They are not on WhatsApp and I didn’t have cell service to call for help. I think they need to up their game with communicating.

Cancelled flight after I arrived at airport after 75 min drive and parking. Next flight was 4 days in the future. Had to scramble and buy a much more expensive flight on another carrier.

I liked the turn-style feature at gate 209B at LAX. Very efficient process. The gate staff also made several, clearly directed announcements so I felt very informed.

The seats were awful, hard plastic covered in sheet vinyl. The airline tries to scam you into paying extra to get seat together when the flight wasn’t full. They were going to separate a family with young children but my wife who had a row to herself gave up her seat so the young mom could be with her young boys. I’m never giving this airline my money again.

It was a short flight so no food or entertainment….

Frontier had yet another flight cancellation. Have never made a complete round trip with this airline without at least one leg getting cancelled. Miserable flights - dirty, uncomfortable planes that apparently always have issues since I've had multiple delays and cancellations with them.

Flight was delayed 3 times, would have been nice to have received text message instead of email notifications. Frontier app wasn’t even updated accordingly, no gate number disclosed. No agent at front desk of gate to inform of delay. Very confused and left if the dark

They changed the timing , first delayed by 4 hours then went back to 40 mins late, we had to run back to airport to not miss our flight. This is ridiculous

No frills for sure. No gate announcements about flight delay, not even water to drink on the flight.

I loked walking out on the tarmac to board and no first class. I didn't like that they have no snacks or onboard wifi to bide your time.

It was a redeye flight, so every passenger just wanted to sleep, but through the entire flight, the flight crew made announcements over the loudspeaker at maximum volume every few minutes making sleep impossible. For example: it’s 2am, and the crew decides to give an extremely detailed announcement about snacks and beverages for sale. And 3am is the perfect time to wake up everyone with a lengthy announcement about how to get a coffee refill and how to take advantage of new offer from frontier for a credit card.
