Everything was good. But from Frankfurt to Seattle in airplane entertainment system didn't work good.

Flight was cancelled due to maintenance issues. It was a nightmare to get an alternate flight back home.

Service and food were excellent. Incredibly friendly and competent staff. Flight was delayed over and hour and I had to run between terminals to get my connecting flight.

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.

I ordered Hindu meal and expecting a vegetarian food. Instead I got Chicken. Also entertainment system was so bad and slow I was never able to use it

I liked crew, always smiling and provided the best services.

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.

Layover time was not sufficient as the gate was too far, I had to literally run and was out of my breath. This was main drawback. The crew was wonderful and so is their service. I loved interacting with them.

They didn’t have my special meal I requested. It seemed like they just put a sticker on a veg meal for me. I had a little bit of it but it didn’t taste good and I got sick from eating it by the time I boarded my Frankfurt to NY flight

What could have been better was holding the flight when our ORD to FRA flight was a bit late. We sat at FRA for 7 hours. It takes time to go through passport control and to get to a gate at that very large airport. We went as fast possible to our gate but were too late. Cityline is a good provider other wise.
