Airline reviews

Lufthansa was great. Crew on board excellent. Frankfort passport control horrible it took about two hours to get through. After waiting in line for hours there was a discussion with the passenger in front of me that was taking forever. The couple behind me had a connecting flight to Turkey in 30 minutes and asked border control officer of her situation and the control officer told the couple in a nasty tone if you don’t like it you can go to another line which would have surely made her miss the flight. Border patrol officers were not helpful. Finally made it through I had to exit and reentry for security check for my connecting flight which Lufthansa changed gates and I had to run to get to A60. Which it seemed 2 kilometers to get to but I made it. If i fid not have 2.5 hrs layover i would have missed my connecting flight to Milan. Not sure if I will fly through Frankfort in the future.

When our flight was canceled and rebooked, my husband's meal request was not transfered. As a result, there was nothing he could eat for dinner and breakfast on the new flight, save a side salad and roll.

Very efficient and excellent service. Nice amenities and beautiful plane. Elevated meals. Boarding could have been more organized. We missed our connecting flight due to EU entry but Lufthansa was extremely quick to rebook us.

Missed it by a couple minutes and couldn’t find an alternative flight so had to spend the night in DC and after much shuffling from 1 airline to another managed to get a United to Frankfurt.

There were only 2 toilets and one of them did not work in business class. We are not allowed to cross classes so had to wait in line to use the toilets!! The entertainment touch display was finicky and did not work all the time.

The flight and crew were good. The customer experience on the ground could have been better. We had to reschedule our flight because of a delay on the previous flight. The attendants working the desk in Washington DC were not helpful. They told us to scan a QR code and that would get us rebooked. Why couldn't two people standing at their computers do this? We had to chat with someone to get everything figured out. It was extremely confusing.

good entertainment package but rather small seats for business class

The male attendant has zero personality. It seemed like he was over worked or hated his job, not once did he smile or made any contact with the people on the plane. Strictly business and call it a day!

Our flight was delayed for over an hour due to weather, and it had already been a long travel day. However, the crew was calm and compassionate, listening to every complaint with genuine concern. They got us home safely without incident, in spite of all of the obstacles. I’m grateful.

Bad! Disaster!! The LH419 was cancelled after 4 hrs on board with no AC and no toilets
