Crew was friendly and helpful on a very full airplane. They did their best to check on connections to let us know if we were going to miss our flights or not.

Flight was delayed nearly an hour causing a very tight connection in Calgary.

Boarding in Frankfurt was pretty good as all zones had their own gates- somethinh I am missing at YYZ.

Legroom is getting tighter and tighter in the Economy class and meals are getting smaller and smaller as the trays are apperaing bigger and bigger...

Decent service.

I paid 100$ for my seat, for more leg room. It happened that the seat next to me was unoccupied. I thought it would give me an opportunity to stretch out a bit to sleep on the Atlantic crossing. Another passenger's tv didn't work so one of the stewardess told him he could sit next to me. He got more leg room for free. I was cramped and could not sleep because of muscle spasm. The Legal age made it more comfortable but it is not worth 100$

One flight attendant in particular was outstanding, Eva. Because of her, I would definitely consider Lufthansa for our next trip to Europe!! She mot definitely went above and beyond in her service and professionalism.

The crew on The flight was efficient and friendly.

The flight was so crammed. I understand there's the possibility of flying on a fully booked flight but if it took an hour to load the passengers how quickly can you realistically get 400 passengers out? Plus it prevents everyone from having an overhead cubby. You need to reconfigure the flying experiwnce.

On time, clean and comfortable

The only challenge for me was they couldn't take my form of payment on the plane for some food so I was out of luck. I had a Mastercard debit from the states. It is also a loss of revenue for you guys as well. They couldn't take the apple pay from the passenger next to me either. I know it's a lot of systems to update
