Compared to our Lufthansa flight out, it was pretty poor. Check-in was a nightmare trying to figure out if it was Lufthansa or United, the Kayak link kept sending us to a dead link with United. Then figuring out which code was United was a mess - it took way too long. On the flight, the seats were uncomfortable, they were out of all wines but red when the flight started, then out of red after the first beverage. The flight attendant said they never get restocked before they turn around to the US, so it happens all the time. The food was so bad we threw it away. For a long flight, it was pretty terrible.

Great staff. Clean plane, but we were delayed for more than an hour due to maintenance issues and had to board another plane.

Friendly crew, but we were delayed for more than an hour and had to change planes due to maintenance issues.

I was exhausted from a long day. The flight was smooth. The first flight during my 3 week travel that took off on time.

There was a little turbulence taking off and landing but mostly it was too late for me to make my connecting flight to Greensboro. Everything else was excellent.

1 flight cancelled Had to fly out of different city Flight at new departure city was delayed 3 hours causing us to miss connecting flights. By the time we did make it to Prague our luggage did not. Had to wait day and a half for luggage to be delivered. Customer service was not good. Agents did not arrive at gate until 5-10 minutes before boarding

Short flight, crew and staff very efficient. Over all good flight experience.

Inoperable monitor left no entertainment for 9 hours. The crew was not helpful. Food was awful.

I was not aware that I have to pay for the checked bag on the return flight. It was included in the price when I bought the ticket

Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

Original Lufthansa flights were canceled and the alternative route that was offered required cab transfer in New York from JFK to Newark at my own expense. Who can refund these $218?

flight was packed, had to check my carryon bag, tiny snack bag offered, but we arrived on time and thats what counts

Expect Business Class seating to be 2 passengers per 3 coach seats, with center blocked. This is typical for flights within Europe on most airlines. Service was excellent!

They gave us chocolates twice (for whoever would like an extra chocolate - kids did!). I asked for an extra water, and I was given one. Crew was very friendly!

My mother is 87 years old and has knee problems. I have reserved a wheelchair indicating that she is immobile. For her it is very difficult to walk short distances. On arrival in Frankfurt, I was called via my mother's phone, by the female employee who had my mother in a wheelchair. She asked me how many and what color suitcases she has, which I explained. I was very surprised when 15 minutes later my mother walked out with her cane and balancing with great difficulties assisted by a young couple who were pushing her suitcase. Where was the wheelchair and the airport employee? I find this to be a disrespectful and abusive behavior of elderly people. It also raises the question of professional misconduct of the airport personnel in Frankfurt i.e. the female employee who abandoned an 87 year old immobile person by the luggage lane. I would like to inquire about the details i.e. name of that employee.

Crew was nicer to some people than others for no apparent reason. I had to get an older lady’s attention because she was too busy talking to passengers.

The flight was wonderful, especially the special assistance from airplane to airplane!

All flights cancelled with no way to reach the airline

The passenger next to me Goran Goranov (elderly man in his 70s on his way to visit his children and grandchildren in Washington, DC) dropped his neck support pillow while boarding - none of the ground crew helped him. He subsequently lost his green card somewhere on the plane or on his way to the other airplane. I hope he found it. I am worried about him. His son had requested an agent to wait for him at the gate - nobody was there when Mr. Goranov came out of the plane Sofia- Frankfurt. Other passengers had to help him get to the next gate for Washington, DC. I hope Mr. Goranov found his Green card and got safely to Washington, DC to spend time with his family during the holiday season.

J ai resté plus 5heures dans l attente du vol et je n'ai pas pu être à l'aise et le retards d'avion ça me dérange et c'était très dur journée pour moi malheureusement
