For a quick trip to athens they did a great job plane was spacious, and we boarded quickly.

it was hard to find the check in at the airport no signs food was average

Short flight. Was not told if there was a kosher option for the snack.

Lost my bagage on the first leg of our trip. Not even on the transfer but on the first flight they didnt put our bagage

The crew aboard Aegean were excellent, they picked on our son’s anxiety and immediately came to the rescue to see what they could do to make it go away.

My experience with a GNA was extremely poor. My original flight was canceled. They put me on another flight. Four hours later. They changed my seat number to the last row where I had no room at all and it cost me $120 for luggage. Additionally, I missed my ferry in Paris Athens. I had to rebook my ferry and I could not get a refund so by them canceling the trip for four hours it caused me no ferry to go to Betsy. I had to find a room that night. The only one I could find was at the Hyatt grand in Athens And I lost a night. Stay at Betsy that I had already prepaid so no my experience was awful. Additionally, they never said on any intercom that Greece was one hour ahead of Paris so that was a problem. We had no idea and when it was never communicated to us

Ove Aegean Airlines! Used them for several flights over past 4.months. never flown w them before but will certainly use in the future!!!

A thoroughly enjoyable experience in business class, which we “won” in the airlines lottery In exchange for a relatively small deposit. The breakfast served at the beginning of this three hour flight was absolutely phenomenal. I would be tempted to fly Aegean airlines on a transatlantic flight in light of this experience.

Was grateful that this flight was held for us as we were late from our prior flight.

Our connecting flight from Barcelona to Athens was late and it appeared that we would not make the connectimg flight to Telaviv. The plane ended up waiting and we made the connection. The airline redeemed itself.

First -the flight was late - more than two hours Second, not even a bottle of water at bord to give for free for this inconvenience. Three-at landing ive realised that I've lost one of my ear plug headphones and been very desperate to find it with my torch, the crew not helped at all more than that they asked to leave the plane as everyone did before me. This was the last flight from that day- extra 5 min for me with a bit of help from crew - would have bring a super review. I guess this days humanity disappeared!

I got caught using a stolen credit card number. Michelle Siziba is my name Nice to London Gatwick on 7/31/25.

Not happy with price of luggage or that we had no choice but to pay whether cabin or hold. I didn't book seats but this is unnecessary extra money along with suitcase

We accidentally purchased twice the bags we needed. Our fault, but the ticket was not clear to us, and it asked us to purchase bags at checkin. When we notified them to get credit back at the airport, they said to contact customer service. We flew the flight and then contracted customer service. They said no credits after the flight has flown. Not customer service oriented at all. They know we didn’t check that many bags and kept our money for a service they did not provide. Be aware and very careful of what you are purchasing from them because they will not make it right if there is an error.

sadly in Basel & Naples- no jetway we had to climb up and down stairs with our max size carry-on luggage, which was not fun!!!

This was our first time using them. I gave okay ratings for food and entertainment because it was minimal or not provided so I couldn't judge, but much better than most budget carriers we have ever used.

We were charged a ridiculous amount for a name spelling error on ticket which I would’ve corrected if I received pre-check info more than 1/2hr before flight. Then we were told at ticket counter that our bags were fine for boarding but then we’re charged another ridiculous amount to take in our luggage despite being told differently. Flight itself was great. Charges were unfair.

Apart from an email about re configuring passenger seating less than 24hrs before flying it was all good.

There were a lot (4 I think) of EasyJet flights leaving Agadir, we arrived two and a half ours before our flight. Very slow to get through the booking in, passport control and security!! We had booked in on line but had to Queue with others who had not to drop our bags off!,

We boarded and then sat on the tarmac for an hour….probably not E Jets fault. But the gentleman that checked us in and took our luggage was exceptionally friendly and calming for early morning/ confused passengers. As always, it’s the people that make or break an experience, right?
