Cabin crew were absolutely fantastic. Couldn’t have been more helpful to me and my twins and family. Great crew!!!

Highlights were the food and wonderful staff. Airplanes were exceptionally clean.

Aegan Airlines compensates for its outdated business-class seats with excellent food and onboard crew service. Launge was also excellent.

On every Aegean flight it seems, they ask people to check in carry on luggage. That seems to happen less often with other airlines for some reason. The food is very basic for a full service airline. We do not need a meal with trays, but something of higher quality (even just higher quality pies) would be better. The cabin crew was very nice and professional, though.

Seats that recline. Ice for soft drinks. No charge for did drinks. Wifi.

Internet not working during the flight - what a big miss!

Aegean Airlines was great! Great spirit, very helpful and efficient. Overall Aegean Airlines was a great experience.

The crew was awesome. There was a school group of about 60 14 year-olds. The food is standard greek fare, Baklava was pre-packaged like it would normally be sold in a vending machine, and it was the highlight of the meal. Plane was in great shape, and seating was like a any A319 you would experience at a national-level carrier (i.e. not like Ryan Air). Like many European airports, they bused us to the plane, so the process of boarding groups is useless, and not well understood by infrequent travelers.

Lovely experience with Aegean. The crew felt with some extremely rude customers with professionalism and poise. The flight went off without a hitch and even landed early!

Got boarded on the plane on time and held there without moving for 2h to avoid paying delay fees. typical Aegean airlines. They should have left us on the gate and do the boarding when we are ready to go.

Nothing! They canceled our flight to Greece the morning we were supposed to leave and offered us another one 5 days later (for a 9 day trip). They said it was an “operational decision”! Yeah a 777 that was 2/3rds empty, so they probably sent it to the Middle East to make a fortune getting people out of there!!

They sat my 2 year old in the seat behind me, separate from myself and my 5 year-old daughter. When I asked them to fix it they told me to speak to the gate agent in London. When I asked in London they told me to talk to the cabin crew. Then a “Supervisor” stuck us in row 39 at the back of the plane when we were originally sitting in row 25/26. They ran out of food which was gross anyway, and the entertain didn’t work the first hour of the flight. Overall terrible experience.

Last minute charge for 1 checked luggage before boarding which wasn’t mentioned when we bought the tickets months ago. It was an unexpected surprise. We had no choice but to pay to board. Most airlines allow your first luggage free.

Our luggage arrived 2 days late when we reached Santorini. We were without cloths and toiletries for two days and didn't had time or means to go and shop everything at reasonable cost. Even though, we filed the report immediately at the airport, there was very less communication to us about when we would expected our luggage and even when it arrived there, they didn't had staff to deliver luggage to our hotel, so we had to go to airport to pick it up, which is very difficult and annoying to do in foreign country where you don't have you own vehicle and you don't have time because your tour is packed with activities. They could have tried to expedite the process and kept us informed and deliver the luggage at our hotel. Also, should have given us compensation for it.

the airline check in attendant made me check my carry on bag which was VERY small and contained medicine for both of my parents stating it was a full flight. Upon boarding there were several open seats and available compartments where my bag would have fit. DO NOT SELL tickets inclusive of a carry-on with the intention of REQUIRING people to check it.

Absolutely the worst airline. Can’t find anything positive to say. We were in business which is the same as most airlines coach

When checking our bags we were told our bags would go through our final destination. This did not happen. When boarding, after group 3 it was a free for all, everyone boards. When served lunch, I asked for anything without dairy, I was given popcorn and gummy snacks. She said she would come back with more options, she never did. Also, when traveling through London, they don’t tell you your gate number until 1 hour before flight leaves, causing everyone to run to their gate.

Horrible. The Athens to London flight was horrible. At some point there was a long piece of toilet paper on the corridor floor for 30min, crew were stepping over it. Only picked up when they rolled out the garbage cart. Not a pleasant site. The whole experience reminded me of easy jet. Not worth the price.

One particular crew member wasn't helpful in the cabin .

More than 3 hours delayed. And they knew about it the night before already. I had a laugh when the captain said - don’t take out your frustration on the staff. Before take off Business class seats had very little space. My knees were digging into the seat in front
