Nice business class service for shot flight. Especially when the free WiFi works

I liked bumping up to Business for less than full price. Also the option to choose your own meal online. In retrospect I would have gone with the standard meal option, but c'st la vie. Overall pretty standard flight, got good views of Greece as the sun rose. That's about it.

It was a short flight (2hours) so the tiny, tiny seats were somewhat tolerable. People with long legs had their knees up to the chair in front of them, quite uncomfortable. I was pleasantly surprised they served a small meal which was quite good. Staff were all great.

Boarding in BCN was really poorly managed. No communication from airline staff and no signs as to what groups line up where. It was just guessing. There were delays that were also not communicated so everybody was standing in line for almost an hour.

they were good. they coordinated pick up of luaggage at final destination. The had text updates on phone with gate/dep.time etc.

I love flying with Aegean. Crew is always polite and empathetic. Boardi

The flight was good. There was free WiFi which was fantastic. The crew was a bit rude and short tempered. The landing was super smooth

Flight was late leaving which made connecting in Athen very hard. Baggage took an hour to come out. Come on… for such a small plane. Need to step up your game Aegean!

The flight was delayed for no reason by 30 min making my connection very hard to get.

Flight had delays as always. It has been very disappointing as the last 4 times I’ve travelled with Aegean we always had delays.
