My flight was delayed and my second flight missed despite a three hour connection in Düsseldorf. My luggage was lost and it took three hours to recover which was actually unfortunately very much barely possible. I needed to rebook a flight that was three times the original cost of the original flight which now I need to go back and recover from the airline. Terrible experience,

My flight was delayed and my second flight missed despite a three hour connection in Düsseldorf. My luggage was lost and it took three hours to recover which was actually unfortunately very much barely possible. I needed to rebook a flight that was three times the original cost of the original flight which now I need to go back and recover from the airline. Terrible experience,

Easy checkin, fast luggage drop off, quick boarding, early take off and arrival. The perfect flight! Thanks

Nice to have reclining seats for a change and great to have internet access

Tivat airport really needs to up its game W Eurowings needs to provide support at luggage collection

Delay after delay: no information besides what my Kayak app provided was provided about the delays. The plane was at the gate. Also, the gate, 100A, was incredibly warm, and the sun was beaming in. Boarding was disorganized with no groups announced.

Kayak - EDreams - Eurowings need to define clearer the hand luggage terms. I asked for add. hang luggage got charged by Eurowings for having add. hand luggage that was not included in my booking. I travel alot! I know the size dimensions never paid twice for hand luggage and cannot chase Edreams or put Eurowings in the wrong. Also there was severe delays on this flight. Issue getting bus on arrival and missed connections. Unfortunate will not use Eurowings

We checked in 4 luggage and only got 3 back & lost our 4th luggage. Our flight was from berlin sept 22. We arrived Copenhagen but only received 3 luggage. Missing 1 still 24 hrs after our arrival and our Cruise will be leaving tomorrow 9/24/2023. This is the second time that our luggage gets lost/delayed in Copenhagen

No food on plane.. flights scheduled 55 min..everything is very expensive on aeroport

Filthy plane, obviously not cleaned properly between flights, food crumbles in seat and carpet

Smallest seat I have ever seen. And they had a label with more Legroom but in fact where really tiny.
