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.

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!

When a flight has a delay of about an hour it is customary to announce the passengers

Plane from Skiathos was 40mins late and we arrived at Athens in a completely different terminal to the departure gate. Myself and my daughter had to run for over 15mins to get to the gate at the far end terminal and we made the flight by 3 mins. The distance from arrival and departure should have been explained, so very stress full of r myself and daughter.

The weight and balance of the aircraft was wrong. It took the ground staff 2 hours to find a forklift to reposition a large heavy crate from the back cargo hold to the front cargo hold. I watched this from my seat. The pilots told us we would be 20 minutes then another 10 minutes delayed waiting on the tower to release us.

There was a departure delay of at least one hour. We also waited in line for 40 minutes and then in the bus for 20 minutes.

It was a short flight so food and entertainment wasn’t necessary

The flight went well, but boarding via a shirtless bus was unpleasant

My flight was supposed to leave at 8:35 and arrive at 9:35. The plane took off at 9:20 and we arrived after 10am. Horrible experience and zero organisation.

Relatively good for a LCC, free water and a biscuit, free standard seat selection at check-in. Just be wary of legroom if you're tall, and the boarding process was very disorganised with no announcements and no queue management.

Do not check bags with Sky Express! We were flying from the Milos airport to Athens. Sky Express lost our checked bags. We were on our way to a wedding in Athens.. In fact, more than half of the flight’s passengers had their bags lost / left at the terminal. This was not a large plane (~50 people), so having left that many bags at a very very small airport where there was only one other flight (from another carrier) scheduled that day, is a ridiculously large oversight. Our bags were sent on a meandering ferry to Athens the following day, to arrive at our hotel 3 days later, but it was too late to be helpful. We had to buy outfits and toiletries, etc when we arrived for the event. We are filing a claim with Sky Express for partial reimbursement.

Never heard about them before and was surprised how organized and efficient they are.

These were tickets purchased with a stolen credit card number.
