Awful, tons of delays, I got into Chicago multiple hours late meaning I hit the very traffic I tried so desperately to avoid. Just empty apologies from American Airlines text alerts. Trash behavior from a trash airline.

Awful, tons of delays, I got into Chicago multiple hours late meaning I hit the very traffic I tried so desperately to avoid. Just empty apologies from American Airlines text alerts. Trash behavior from a trash airline.

The boarding was as always, the crew tried their best but not enough. The food was a disaster I had dietary restrictions that were half met because the company did not loaded the food for the flight. The entertainment screen was fine but content was not and also they removed the free messaging option from the flight and they charged 30 dollars for that crappy bandwidth. This flight is not worth the cost and the company is going down on quality.

As smooth as you can expect. Some issues with boarding because the previous plane took forever to deplane but overall, a good experience.

DFW-LHR Toilets not kept clean Too cramped. Aisles so narrow crew were constantly banging into people on the aisle seats. Even then, the carts used are reduced width. Other than that it was a decent flight on both legs

Excellent customer service at check in at Austin flight to DFW and excellent customer service from Karren in terminal B at DFW.

The flight itself was fine, but between the man in front of me putting his chair back, and the gentleman next to me who took up 50% of my seat, my back and neck are destroyed from the flight. I’m hoping for a better outcome flying back.

Flight boarded without pilots. Sat on plane for 3 hrs. after over an hour late boarding. Plane never took off. Had to deplane near midnight. Line for rebooking was 3 hours + long. I had to leave.

We were told there would be no food/beverage service due to turbulence. There was very little turbulence on the 2+ hour flight. I was in First Class and thought they could have done a quick service after take off as they had a quite bit of time before we would be reaching the predicted turbulent area. They could have at least passed out a quick bag of pretzels.

Very disappointed with the crew and the lack of attention given to the passengers. On a 5 hour flight they never offered a snack. One time offered a beverage and didn’t pick up the used cups until the flight was on final approach. The two flight attendants in our section mentioned that they were best friends and compared their pre flight shoes. When paying for first/business class there is a level of service that should be expected. These two spent the majority of the flight in their seats playing on their phones and laughing with each other. Very frustrating!!!

I love the Kayak has keep on updating me about flight status as it was delayed for 30mins. as well notifications to book seat and if any change on booking. Tickets were also cheap compared to British Airways online website. No hidden charges or terms n conditions. Keep it up!!!
