the guy in front of me put his seat back immediately...and then left it back including thru landing and taxiing to the runway. attendants did not check/ask him to put it up for landing.

The airplane was an old airplane, seats were very uncomfortable and very little space, they changed my seat and that was no option to get back into my seat even when I was traveling a senior who required assistance.

This is not a low cost airline. Stop acting like o e.

Aeromexico crew made me check my hand luggage in the door of the plane. As soon as I reach Mexico City, I notice that my luggage was opened and 8 games of Nintendo Switch were stolen (700 dllrs value aprox) (the console was there) but the games were stolen. I am very dissapointed of Aeromexico and all the crew. Instead of being a good trip, It was a sad trip

Ok. But we arrived to a remote terminal which meant that a bus had to take us to the terminal building

Old aircraft the audio of the entertainment dosent work Dirty seats

Terrible. The flight arrives 2 hr later, no AC. One of the worst flights ever

Boarding - It is unclear where the line for the group are given the signs. A solution would be a diagonal arrow pointing to the lane in which the lane for boarding of a given zone should form. As it is now, you are guessing which side of the pole the "zone 3" sign is telling you to form the line. Inflight Entertainment - The Spanish subtitles function didn't work for movie watching (in fact, all subtitles didn't work), so was difficult to follow along and I watched the movie in silence without words.

An hour-long wait to check in, 90 minutes for luggage to come out, lost luggage, chaotic operations

Atraso de dos horas y media con vuelos sobre vendidos

Good overall. Cannot fault the airlines. I have had better entertainment systems before ie ice in Emirates but it was not too bad. Food was decent and staff were friendly.

I did not fly by vergin atlantic from bangalore to vasco da gama

Your flight delayed at Heathrow n I almost missed my mother funeral.you idiots. I had to waste 10 hours in different airports. Thank your stars I'm not suing you.

Miami airport needs more thorough signage. It was a long walk from my transport point to the check in desk,

Flight took off an hour late. Had to stay on the tarmac for half an hour after landing. Both annoying.

We had an unfortunate experience where we had to leave the aircraft after boarding, shortly before the scheduled takeoff time, and re-board. The reason given was that a passenger felt ill and had to cancel their plans and therefor their luggage had to be found and removed.

We’ve used VA before many times the experience is always been good they have lovely staff and the food is always delicious.

Everything about the flight was amazing from check in to boarding entertainment was okay food we didn’t try.

Seats were old and dirty, for a long haul flight you expect to be able to recline and for the av to work properly. Choice for vegans was fruit….

The Virgin Atlantic crew was very good. However, the equipment was OK, the seats were OK, but her bags did not arrive with me. Two bags showed up a day later and I’m still waiting for my third back.

Crew was great and responsive. Entertainment quit working with about 4 hours remaining on the flight. My seat cushion was broken.

Not very good , the stewardess were unfriendly and they don't like to be bothered. Cos was a night flight and they need to sleep.

British Airways staff are very polite and willing to help.

On time arrivals and departures. Gate boarding notices could be better if displayed on monitor.

American Airlines Suck. AA did not deliver us to the airport we paid for to Tulum. Instead, we were flown into Cancun and had to take a shuttle to Tulum. Instead of arriving at 4 PM, we arrived at 11:30 PM - not to mention that our initial booked flight was due into Tulum at noon. The latter flight was canceled and rebooked (to the 4 PM arrival). We lost a day of vacation. Oh, I forgot that AA provided a lunch voucher for $12. Noting, the least expensive item on the menu at the airport restaurant was green beans for $9.99. The return flight from Tulum was delayed two or three times for no reason other than that it was NOT related to the weather. We arrived late for our connecting flight from DFW to STL. Luckily, the connecting flight was delayed. We hurried through Customs and ran through the airport to make our flight to STL (or we would have missed that flight).

2/29/2025: Tulum to DFW. Delay as usual with no explanation from AA. Three friends and I had a connecting flight from DFW to STL. We would have missed the latter without the delayed connecting flight, dashing through customs, and running through the airport. Did I mention our trip to Tulum on American was rerouted to Cancun and shuttle from Cancun to Tulum, arriving at our resort destination at midnight vs the 4 PM scheduled arrival? AA provided a lunch voucher for $12.00. The least expensive menu item was $9.99 for green beans. I will avoid traveling with AA as much as possible.

The drinks selection could be improved some. I like the fact that I can pick my seat and get upgraded fairly ofter.

This particular flight wasn't very full at the back, so there were three seats available for spreading out and getting relatively comfortable

Lack of communication with customers through the delays and poor audio during boarding. No assistance to serve a number of customers with limited time between connecting flights. Lack of empathy from staff. Rebooked on a flight that seemed solely for purposes of taking those that missed their connection the night before. The hostess at the gate arrived late and never expressed any form of compassion or friendliness toward passengers. Just get them on board, so I can go in with my life. Will never fly AA again.

It was good overall but the prices of snacks are ridiculous.

From my experience, I see there is room for a greater mixture of cultures, for example, a mix of the nationality of cabin crews, food, music, food, etc.

on time quick service but food so so and seats very small. no leg room. I think passengers should not be bringing so large carry on suitcases and should have free check in. Then boarding and unloading would be faster

Bug wouldn't let me upgrade my 17 year old son to an exit row preferred seat even though conditions clearly stipulated 16 years minimum. Luckily no one else took the seat so a supervisor was able to force quit my son at the gate. Could have been a real problem had we been separated but all is well that ended well.

After nearly nine years without traveling, my son and I decided to take our first flight, and we chose Air Canada and I’m so glad we did! From start to finish, our experience was nothing short of amazing. The flight itself was smooth, comfortable, and truly enjoyable. The staff were warm, professional, and went above and beyond to make us feel at ease. But what really stood out for me was the luggage tracking feature. Knowing that my bag was scanned onto the same flight I was on gave me such peace of mind. It’s little details like this that make all the difference, especially after not traveling for so long. This trip was incredibly special for us, and Air Canada made it even more memorable. Thank you for such a fantastic experience I wouldn’t hesitate to fly with you again!

Missed flight to Kamloops with Air Canada. They did not hold the plane when I was delayed in security. Could not provide another flight for THREE DAYS. Provided hotel, however I had my husband come to get me. This needs to be compensated.

The main issue i had with this flight is the crew kept the plane super warm. A number of passengers i saw were sweating and fanning themselves. When we asked if they could lower the temperature, all we got was some crass dismissal from the head flight attendant the she couldn't feel the heat cause she was going through menopause...?!

My flight from Mexico City to Boston would have been fine, had I taken it, but because the final leg of the trip from Toronto to Boston was cancelled, I decided to fly on another carrier out of Mexico City that offered me a non, stop-direct route. Prior to this, I received several emails and text messages from Air Canada in regards to their Toronto to Boston flight being cancelled and about a similiar flights that departed much later that evening or the following day from Toronto to Boston. I would have hoped that Air Canada would have offered to seat on AeroMexico, but they did not. I flew on AeroMexico from Mexico City to Boston (direct) and enjoyed a wonderful flight. I replied to texts Air Canada's about my situation, but got no response. I have asked to be considered for a partial refund from Air Canada for the missed portion of my flight that I took with AeroMexico. I have yet to hear back.

On time, comfort, service. No breakfast available as per menu, the chicken wrap I got instead was poor and poorly presented (in Saran wrap, as if made at home by the pilot)

I arrived for my flight and was told I was now on standby as my assigned seat when I purchased my ticket was just deemed unusable 15 mins ago. My parents had to wait and hour and a half at the airport to see if I’d get in the plane. Finally when all passengers had boarded the plane I was finally told they did have another seat for me. When I boarded I saw someone else sitting in my originally assigned seat. It was in the emergency exit row and has extra leg room. I have sat in this row many times and am able to help in an emergency so no reason for me to have been kicked out of this seat. The new seat I was assigned had no padding and was extremely uncomfortable. Upon landing my back was very sore and I will probably need to see a massage therapist to help ease the tension. There was no tv or way to charge my phone on the plane. Worst flight I’ve taken in a while by far.

Put first the requirement visible of the eta visa for no have problem in the airport at last time hour. Thak you.

Boarding was delayed and we had to get on buses to plane so group # didn't matter. No food or drinks served gratis. Seats were small, knees smashed into the seat ahead, didn't recline. Crew was excellent though.

The flight from Seattle was delayed, which made me miss my connection to Florence. I was re-booked NINE HOURS LATER!!! That’s basically a vacation day lost. British Airways needs to partner with other airlines when possible to get a more realistic travel time, if delays occur. I realize there aren’t many flights to Florence from London, so I would book differently were I to return. The actual flight from Seattle was very comfortable and the crew was great, no faults there. I enjoy British Airways, this was an anomaly.

Our original booking with Kayak -our first experience -was exactly what we wanted and worked well. Updates were friendly and reassuring as were the contacts with UnderPricer so a big win-win. We learned a lot on your reliability and will definitely put you on our organisational list for the future.

The crew could not have been more helpful, my meal was excellent, I slept peacefully until right before landing, and the BA lounge was a godsend. The only negative I encountered was the coffee both on the plane and in the lounge. Not to my taste but that’s a personal preference.

Plane and seats ok. Dinners going and coming back were not fantastic. Breakfast from Seattle to London fine with bagel, cheese and fried egg. Second meal on London to Seattle not my favorite of kind of pizza sauce in a pastry. Came with water about three different times on each of my long flights. Staff on all very friendly and helpful.

I don’t understand why a reputable airline like BA would delegate their London flights to AA. Makes no sense to me, as most domestic carriers do such a poor job these days. Terminal 3 at LHR is a total dump

We ordered kids meals - which were not kid friendly at all! (the breakfast that is - scrambled eggs on a bed of spinach and asparagus?)

Uncomfortable seats. Crazy seat assignments separating families when they could easily have put them together. Good communication from pilot about arrival time after delay in departure. Toilet ran out of water in sink. Snack box poor for flight of this length.

The bed in Club class was not very comfortable, everything else was good.

Cancelled flight minutes before boarding. Rescheduled flight was two days later
