American airlines suck they delay the flights all the time made me sleep in an airport because my flight was delayed and I miss my connecting flight

There's nothing I liked about it. For first off I scheduled this trip two weeks in advance then they delayed my flight which messed up my whole trip. So I scheduled it for the following weekend thinking there won't be a delay and guess what as soon as I got to the airport we said in the airplane on the tarmac for an hour and a half. Not only was it delayed I missed my connecting flight meaning I had to stay the night at Dallas-Fort Worth airport sleeping on the floor. I will tell you this I will never fly American airlines ever again I have had nothing but horrible experience with them and I just throw money at them

The stewardess hit me with the food kart twice on the head and didn't say I'm sorry once. The same stewardess gave me a warm Apple Juice with No ice. The Flight was delayed for Departure 6 times, starting from 2:36pm, finally taking off 7:50pm. I was late picking up my child from the sitter by 3 hours.

Our bags took a long time to get unloaded once we landed.

My flight was delayed for several hours. Sitting at gate 16 for several hours, I got a text from Kayak the gate changed to 9 before it was announced. Very bad communication at each gate from American Airlines employees. I received 10 notifications of delay from Kayak. My vacation started off horrible! I will write to American Airlines corporate office also.

My Internet did not work for Outlook email or basically anything. I paid for one hour of in-flight usage and it was terrible. I spent a lot of time on different sites and browsers with no luck and a lot of frustration. Other than that, the flight was on time, crew was nice, service was fine. Seat was OK even though I paid for the extra 6 inches. I cannot imagine how tight the seats in the back must be.

Delayed flight that lead to a missed connection and a 5-hour trip became a 12-hour flight 🙄

No issues. They did change our gate FOUR times in about 30 minutes which was mildly annoying but the flight was fine.

Great flight. No issues at all. I still think boarding could be more efficient but otherwise, a good experience.

Crew should be nicer and emphatic with customers. Same cookies as the past 20 years. Seat are ok and the plane was clean though it was delayed.

The seating has become ridiculous… like a contest to see how narrow and short they can be made- forcing anyone over 5’1 to pay more to not be twisting oneself into a pretzel. Really insane- would have thought BA was better than this. Frankly- it cancels out a lot of the positive aspects.

flight was delayed from BWI to London - missed my connecting flight & then connecting flight (also British Air) was delayed - food is awful, TV & movie selection is great

Super tight economy class. My knees were hitting the back of seat in front of me (I'm only 5'6"). My small backpack (sized according to their required dimensions) would not fit under the seat in front of me because there is a box (is that the life jacket?) in the way. Over all, extremely uncomfortable. I forgive the tasteless food, but the tight seating was torture

First time on BA but will fly with them from now on! Everything about the flight was superb!!!

Didn’t fly with them as someone had cancelled my flight

Some how my flight was canceled, neither BA or Justfly.com accepted responsibility. I only found out about this the day before when I tried to check in. I had to book another flight which due to the time ( day before) cost me $300 more. I was still receiving notifications about the flight even when I was on another flight from you. So no my flight to London was not good.

Online check-in 24 hours in advance something seems not so easy to check in to pick seats and to print a boarding pass

I like the crew, very welcoming. Food can be better. The seat arms don’t go up so. I could use the empty seat next to mine to relax better. 3hrs delay 😠

Very crowded, no real explanation of food "chicken or pasta?" After dinner no drinks service. Plane was clean, but little help with finding soaces fir luggage to get into overhead bins. Many passengers putting 2 bags, hats, duty free in overhead bins so no space for roll ons

Only for BA because we had to get to Edinburgh at a certain time. Baggage lost, late boarding with only one person checking, again, our passports and boarding passes until the despatch controller had to step in to get us away. Will never fly BA again.
