When I booked my flight a month ago - I selected a seat. That seat was NOT the one I ended up with when I checked into my flight the day before. This is the second time this has occurred. So, I checked my next flight on Wednesday and Thursday and no seat was assigned. Poor, very poor customer service.

When I booked my flight a month ago - I selected a seat. That seat was NOT the one I ended up with when I checked into my flight the day before. This is the second time this has occurred. So, I checked my next flight on Wednesday and Thursday and no seat was assigned. Poor, very poor customer service.

Flight boarded from Gate 159B, the farthest gate in the LAX Bradley Terminal. While the flight operated on time, the first class cabin attendant made no recognition of my being an Advantage Executive Platinum member.

British Airways is an excellent airline. Comfort, food and airline personnel.

We changed our flight because of weather. Unfortunately we were on hold for over an hour, but since we were 5 people who all booked individually, we felt more comfortable doing it with an agent. It all worked out in the end.

American Airlines did everything they could with the high Spring Break crowd. I was frustrated to be changed from 1st class to a middle seat at the back of the plane. This has happened before, not sure booking 1st class and paying the extra actually works.

Older airplane with worn out seats. No entertainment system at all. Connecting to Wi-Fi was problematic and hit and miss.

I didn't end up taking this flight. I got up at 4am for a flight that was supposed to board at 6am - at 5:55am you delayed the flight to 10am. The airport is under construction so I switched to a later flight as I wasn't going to sit in the airport for 4 hours. They said the delay was due to the crew needing rest from a flight coming in late the night before - if that was the case then I think you should have delayed the flight much sooner so that passengers wouldn't get up so early and get to the airport to sit and wait.

I very rarely fly American and my experience today reenforces that is the correct decision. While the staff were all very courteous, our flight was first thing in the morning so there was no reason to be delayed, yet appropriate maintenance checks weren’t completed prior to our flight so we were delayed multiple times. Not a great showing, American Airlines.

Boarding is always an ordeal. Less dogs on flights. I am highly allergic to dogs and cats. Why are there so many animals these days?

I was on a small regional flight from Detroit to Philadelphia. When we landed the outside cruise needed to turn something off with the engine, which took quite a long time. Then, when they allowed us to get off the plane it was outside. They took their time, unloading all the luggage and waited till they unloaded all the luggage before they brought it over to us. It was 9 o’clock at night freezing cold out, and there was no proactive hustle to try to get people their luggage. It was really one of the worst experiences I think I’ve ever had with American until a manager came over. I don’t think they were going to even consider pulling the luggage over to the people that had been waiting outside for at least 10 minutes in the freezing cold.

Stewardess was not attentive at all asked for a bottle of water never came by 15 minutes later I asked her she said that she forgot there was only 12 people in first class and two stewardess unacceptable I ordered the fish was the last person to order. They said that they did not have any had to have a different item pasta at the inside of it because I was diabetic. Worst experience I ever had will never travel this airline again.

Very nice staff, terrible food, not very comfortable premium economy.

Boarding, crew, food and baggage handling excellent (no bags lost, yay!). However for an 8 hour flight, there were limited entertainment options. And really would have liked to have a pillow!

The crew was super friendly and helpful. The food was quite good. An overall positive experience.

Plane delayed due to weather. Plane boarded, then told to unboard due to a maintenance issue.

A more organized boarding experience and better food would have made the experience better.

Was all good.l including a sofdrink. AA improved significantly. There was no entertainment.

why can't planes be boarded from back to front?? everything was great otherwise

We flew into Barcelona and the plane was so cramped and very uncomfortable and dirty. But we flew out of Madrid and that plane was much better. Would fly Iberia again.

For what we are willing to pay for international air travel, our experience was very good. We had no problem checking in, we had very little wait time at the AA counter in Madrid, and the staff in Madrid were very helpful. The flight crew was helpful and courteous, the plane was on the newer side, and our assigned seats were together without us needing to purchase them. The flight took off on time and arrived early. Overall, it was a pleasant experience or as much as could be expected in economy for almost 10 hours.

The crew has always been great on BA. They are very friendly and accommodating. I like that they have vegetarian options already in the menu. And the free wine is a nice perk.) I noticed (both directions of my trip) minor upgrades/ replacements needed on the plane itself (touch screen didn't work with touch; bathroom light didn't go on). However, this is one of my favorite airlines.

Charging for the internet in business is penny wise pound foolish. WIn €20 lose customer goodwill

Everything was spectacular except the boarding. It was just a mob of people while all groups were called over the public address system.

The Britts are wonderful to fly with and the crew were very hospitable. Again, I really wish they had been able to retrieve my carryon bag from baggage claim before the flight so I could be in a less worrisome state of mind, but that's not on them. I completely understand. The window seats with the dimmable windows were very cool!

There was a delay for the San Francisco-London flight, but we were all informed via text and email. The staff was very friendly and nice and the food was good. I do recommend that the airline offer something without eggs or something vegan for the vegetarian meal option. A lot of Indians are lacto-vegetarian, while some could be allergic to eggs/dairy.

food options were terrible. for a 10-hour flight, there should be 2 decent meals. Also, flight attendants should come around with drinks more than just at the meals.

Smooth flight. The seats were comfortable but the reclining mechanism didn't work very well. My wife's seat required the flight attendant to push the seat forward while she pushed the button. The leg support didn't want to return to its home under the seat. I ordered the diabetic meal which was full of carbs. It was low in sugar but carbs turn into sugar so was it really diabetic? Overall the flight was pleasant, long but pleasant.

Crew were nice, food was good. Boarding was horrendous. We were driven around the airport in a bus forced to climb a long flight of very steep stairs with no adequate handrails to board the plane . In many many years of flying to the US I have never been required to do this . There was no assistance for those needing help getting up the stairs to the plane. A fellow passenger helped me. No idea how other elderly, physically limited passengers or those with young children managed . It was a full flight with crowds trying to get up the stairs. It was an accident waiting to happen.

Horrible, the plane is just old and junky...Filthy restroom, seat was as hard as rock. The food, mystery side dish, inedible..geez..just Horrible. Never flying BA again

We paid for Business Class seats, but system did not have us and they were not available.
