As always a terrible experience. AA stole a day from my vacation days planned to be spent with my Family. Response: delays related to weather issues.

As always a terrible experience. AA stole a day from my vacation days planned to be spent with my Family. Response: delays related to weather issues.

Even in the premium economy, I found the seats incredibly uncomfortable. I hated that booking through Kayak, it wasn't clear that it was a Level flight, not Iberia. Everything felt cheaply made and not at all worth the airfare we paid.

The flight was over two hours delayed. The aircraft was somewhat dated.

Luggage arrived damaged and protective plastic was lost. I need customer service to contact me or the number for customer service. Thanks.

Provided a good service and I will use it again. Thanks,

Boarding was not well coordinated. I asked twice at the Level check-in area about the MIA flight. At no point did they say the check-in would be at another counter. Fortunately, another passenger was equally confused and got the REAL story from the airport’s info center. Further, my minor child was tagged “SSSS” on their boarding pass. Level should have notified TSA about him being a minor. Instead, the entire family went through the SSSS process, not just our son. When his name was called out at the gate, it was announced in Spanish. No English announcement was made. The food on board was bearable. The crew was adequate, despite not being Level/Iberia crew (Level contracted out our flight to “World2Fly Airlines” - a company I have never heard of!). The onboard entertainment was very limited. They did not even offer a flight tracker option. Nor were music selections offered. Like TAP and Aer Lingus, I will think twice before booking Level ever again.

This ticket was canceled and I did not find out until it was time to check in. I believe the vendor is at fault. Cheap tickets.com I would like to elaborate on the situation to kayak. Can you give me an email address?

You get what you pay for. In general I like the service and flight attendants.

Excellent! Outstanding customer service, the best service I have received. Food was served, dinner, snacks, beverages, crew was there to greet you. 10/10

Charging $300 to be able to pick a seat next to your wife was nothing less than extortion.

The flight was an hour late leaving Heathrow. The food was mediocre. When we got to Austin, my husband’s luggage was missing. He filled out information at baggage claim. We are waiting to hear something. His name is Henry Jacob Braunig.

We arrived late to London, and consequently were 5 min. late to be allowed through security for our next flight. Even though dozens of people missed the same flight, BA did not radio ahead to hold open security for an extra 5-10 min. to allow people to get on the flight. This caused an additional 6 hour delay in London after waiting over an hour in Customer Service to get rebooked. They did not have enough staff on hand to help people in a timely manner. Not at all happy with the BA's customer care or customer service.

All service prior to the flight was terrible: online check-in not working, no customer service tel,, multiple airport scanners not working, A huge mess.

CONSTANT ERROR MESSAGE THAT THE WIFI COULD NOT BE PURCHASED DUE TO INABILITY TO CONNECT PAYMENT SYSTEM VIA SATELLITE. THIS HAPPENED IN BOTH DIRECTIONS. THE MAIN REASON I TRAVEL IN PRIORITY IS TO BE ABLE TO WORK FOR WHICH I NEED ACCESS TO INTERNET. .

They lost my luggage. Lady who was helping with it in Austin was rude. Not very helpful!

Waited 3.25 hours in plane only to have the flight cancelled.

More space, of course. a footrest! more room to walk. Movie selection was awful. Some good documentaries would help if the movies can't be better. The flight itself was great, crew was great.

Better synchronizing the boarding processes. The audio announcements, the personnel and the digital signage were not saying the same thing. All confusion.

The first class seats were unusable, mine at the end of the flight, my husband's in the middle of the flight, and the one next to me was unusable either, they had to move the person to another seat.

Last minute gate change. Didn’t put our TSA global on our trip even though we asked multiple times to confirm. Did not help with food when could not eat what was served.
