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.

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.

Everything was on time, even though the layover in Frankfurt was 22hrs

Missed flight. Requested assistance for my father and he did not receive it in Paris.

This flight had way more space than my international flight which is just embarrassing

It was as good as a flight in economy can be.

Horrible seats. They were just coach seats with the middle seat blocked with a dirty seat tray.

The entertainment is pretty boring. There are no new movies or TV shows from February. The food is just ok on the Atlanta to Frankfurt leg, but better on the Fra to Bengaluru leg.

I meant this flight was not good, the one from Tirana to Frankfurt was better!

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!
