Very kind Lufthansa agent somehow gave us all no charge extra business class seats and helped us get home rested and happy.

The lounge was not accessible because it was located before the passport control, and backtracking was impossible.

The flight to America was freezing. The overnight flight back to the UK was boiling hot and the cabin stank of toilet or occasionally perfume, even though I was several rows back from either bathroom. Food was tiny portions. Two small pieces of tough and dry beef in random gravy with pretend mashed potato raking up most of it. Very little veg. Salad was ok. Wooden cutlery broke within minutes of using. Lots of old films for entertainment. Some new ones. Generally a bit rubbish.

Entertainment center did not work and no electric available at seat for 11 hour flight. Didn’t have access to overhead light or call button. Food was tasteless and had a high salt (27 %) of recommended daily salt intake

Our flight gor canceled and there was no one to help us but told us to scan the qr code and fill the forms on-line. Very poor service especially we are tourists traveling to Washington DC for the 1st time.

We were delayed for about an hour from taking off due to traffic control procedures at the destination airport. But once in the air, the flight went well. The crew members were great and provided cabin service despite moderate turbulence during much of the flight.

Very thoughtful flight attendant offered me water immediately since I had run to make my connection.

Plane left & arrived early- 5 Crew great. Wi fi - paid for 2, only 1 worked - so so. Waste of $. Coolie was good

The entertainment wasn’t playing in the app or online.

Boarding was terrible. My wife uses a wheel chair and she was in an incredibly hot closed metal cargo box for close to 20 minutes before getting on board

My wife has a scooter and they where supposed to send from departure to destination and had it go to connecting flight,not good.Nobody has knowledge of the scooters or the battery's.

The flight was over an hour delayed. The problem was they had the wrong aircraft at the gate, Joe in the world does that happen?

On time departure & early arrival. Made a long day much better.

Like all planes recently, entertainment is achieved by giving the patron free WiFi and letting them stream shows via the screen on a phone or tablet.

Crew and agents misguiding on tight connections, and lack of connecting crew looking for inbound planes. A very avoidable missed connection as a result.

My flight was 4 hours delayed on departure at 6a causing me to miss my connection at DCA. I had to scramble to find a seat home on a later flight and instead of an exit seat, I was in row 30 on a flight getting me home 5 hours later than planned. The AA team on the ground did a fine job. AA continues to run the airline like the passengers are cargo.

American Airlines changed are gate no fewer than four times. Walking back and forth from one concourse to another was exhausting, especially after all the flight delays.

Hydraulic leak caused the flight to be cancelled. Auto system scheduled us on a 3 am flight. Wevhsedvrebook on the app and hit schedules later in the afternoon. Our luggage per gate and ticket agent would be rescanned and put in our new flight. Did not happen. Our luggage stayed in hsv. Baggage claim in wash dc unable to help. We filed a claim. Several emails about our luggage were in conflict with one another. Called as baggage and was on hold 30 minutes. Oscar said one of 2 was out fir delivery then cancelled. About 45 minutes later both pieces were delivered. Their system is suspect

The airplane was an old model, the overhead didn’t have enough room for people’s items and made boarding and boarding disappointing and stressful. Crew allowed passengers to bring more than the permitted baggage sizes.

It was great. Smooth flight, comfortable, left on time and landed on time.
