Fantastic. The only thing - out of my six luggage one was lost in Copenhagen, however it was delivered Home 3 Days later so all great..

Since our earlier flight was delayed, we missed this flight and were rerouted on Lufthansa 2 days later.

really nothing ...uncomfortable seating, cramped ....no better than a US short hopper flight.. never again

Feels like economy sits are getting smaller especially while eating food

Terrible customer service. The flight attendants were rude. We experienced significant turbulence for a large portion of the flight and there was very little check in from the flight deck. The space was extremely limited to the point where it felt like torture. Never again

I have paid for extra legroom on my flight. My seat was broken and did not recline. The crew could not fix it and refused to provide me with another seat

It was a fairly old plane in which you couldn't buy an internet connection.

The staff were great, the food was good. I just hate being crammed in a tuna can for 10 hours cause I can’t afford a better seat.

Baggage was mis-handled; food and grocery items in the baggage were damaged.

It was a good flight. Everyone was professional and the flight was smooth.
