Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

There was a loud squeaky sound the whole time we were flying.

I didn’t not like that I could not select my seat and ended up with the worse seat.

The landing was bad and the hostess came two times and i was sleeping but when she served the person that nexts to me I woke up and she didn’t even asked me if I need any drink or snacks two times!!!!

Plane was late because of a mechanical malfunction and the food listed as available was not. Flight attendants seem over worked and under paid. They just done seem happy. And that can be seen in their faces.

Waited 3 hours on a plane to de-ice due to manpower issues. Waited another hour and a half once we landed because of a gate issue. Missed my connections. Created. A total of 13 hours of delay.

Great, on time departure, friendly and accommodating crew, great leg room, Smith flight

Plane was turned around due to fog half way into the flight, Delta did not properly direct passengers to stay on same flight and instead failed to properly rebook on Alaska

Honestly, I didn’t expect that I will experience this long time wait during the check in. There was only one person who was taking care of the passengers for the economy class and it took us to wait about one hour to do our check i. As a result we barely get to the airplane as the gate was at the end of the airport. That is totally not professional where one crue is working at the registration desk with economy and 3-4 crues are helping for the business class.

Like most domestic flights in the US, you are basically on your own with this airline when it comes to food, so be sure to purchase meals and drinks ahead of time or expect to arrive starving and dehydrated (like I was).

Iberia was great. American airlines was late for no reason ans with no explanatiom or apologies. We were on the runway for at least 40 minutes before taking off once we finally boarded

Flight was 1/2 hour delayed leaving Phoenix. Otherwise it was an average flight. Flight crew on this trip was very nice.

Horrible - they lied to me about baggage & boarding, even though I specifically spoke to their agents the day before my flight about my issue. When I showed up they did not let me board and stranded me at my airport until I bought a new flight with money I did not have to spend.

Not sure why JAL partnered with American Airlines because their service is no where near similar. Flight attendants were not friendly and didn’t smile. Food was horrible…

The experience was great and much better than the flight going out. of course I was in first class but the service was excellent

Comfort of seats, ease of boarding. Food selection could be better

Food options were limited which is absolutely embarrassing for a Flight of this size The staff did not come around as much and I am not accustomed to such poor service from American Airlines Drinks I believe were limited to soda and water

Crew were attentive and friendly. Flight was smooth and early! I enjoyed the less crowded plane. Thank you!

We are gluten free, there were not any available complimentary gluten free options.

The absolute worst. Our flight from Madrid to Charlotte was delayed nearly 2hrs which cost us to miss our connecting flight. The only availability was to either separate my party of four (two being children) several other locations to reach our final destination. The other was drop us off at entirely different location we never intended on going. Thus resulting in us driving a rental 2 hrs to our original final destination. On top of that the flight from Madrid was uncomfortable and some staff were extremely rude.

Pretty fair for the price of the plane ticket. Food was poorly, but overall was a ok experience for a super long flight.

Good. Madrid to SFO was way better than ARN to Madrid. Mercifully, the seats to Madrid didn't recline. So although there was no leg room, your knees didn't get crushed

Overall was good except for the seat which, for an 8 hour intercontinental flight, was uncorfortable. For that kind of flight seats should have more space, even for economy seats.

Needed more info on connecting flight. Late flight made very short connection. Lost luggage that we still do not have!

Seats comfortable on economy plus and attendants very helpful. Food was ok. Bathrooms needed servicing.

Good food, prompt and timely flight, good on-board personnel

Thankful for 2-4-2 economy seating. Food was ok. Free beer & wine in economy was nice. Served hot dinner, mud- flight snack and pre-arrival ham sandwich. Seat with pillow & blanket. Reasonable movie options. Overall, a good experience. IBERIA APP is terrible terrible terrible.... needs to get upgraded to equivalent of TAP Airlines App. No option to bid or request an upgrade. Very disappointing.

My luggage did not get to my Miami destination/home. I am waiting for it 24 hours later.

Flight was delayed by well over an hour. Communication was terrible.

I like the team but I don't like the food you provided with money. I want free food and free water.

Wonderful service and very comfy in the bulkhead in Economy Plus! Delicious food.

It was very good. We got a late start by about an hour and a half. However I worked rather have that than crash. It was purely mechanical. They had our tickets ready when we came off the plane in London for the next leg. The only mishap was when we got to Lisbon my husbands luggage made or bit mine didn't. All was not lost because I did finally get it 2 days later. I was really pleased that they c made the effort.

The entire process was flawless and as expected flying first class. The only thing that I have a complaint on...when first boarding, the plane was EXTREMELY cold; then when we were trying to sleep, it was way too hot - just better regulating (especially trying to sleep) would have made it perfect.

Lost our luggage in Heathrow. Showed up 3 days into a 7 day vacation. Very inconvenient and disappointing!!

Lost our bags in Heathrow, We didn’t receive bags in Mallorca for 3 days, out of a 7 day cycling vacation. Really inconvenient and disappointing!

Our luggage is missing. We are at the Hotel Gran Via in Barcelona

We paid to have overhead carry-on baggage. When we got to the gate we were told that our carry on bags would need to be checked and go below because the flight was full. Notably we were nowhere near the last people to board and about 30 other passengers also had to check their carry-on bags. Other than that the flight was fine.

Crew were very friendly and helpful. They explained to us in detail the delay in our takeoff due to the storm that rolled in from Belfast and did their best to make up the time. Always great to fly BA!

Not sure if the crew were experiencing something unknown to me,but the service of passing water was non-existent.In addition,please take consideration when providing yogurt as alternative for breakfast as some of us, could be lactose intolerant.. thanks

This was an American Airlines flight. The crew were very unhappy and quite grumpy. Abrupt to the point of being rude. The food was dreadful. Indeed the breakfast was in edible. I will avoid AA at all costs in the future.
