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!

We had a 1 1/2 hour delay before we left Denver. When we arrive to Frankfort, they didn’t announce that people with connecting flights to exit the plane first. My next flight was already boarding when we we taxiing in to the gate. I waited another 10 minutes to get off the plane. I had to run to catch my next flight. I mean run! I made it with one minute to spare, but my luggage did not. My luggage came two hours later on a different flight.

The flight was cancelled due to tech problem with the plane
