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

The plane was late (as was my flight out from Birmingham the day before)

The flight was delayed by an hour. Made the connection uncomfortably tight.

Good service … bus transfer upon arrival from plane to terminal: atrocious!!!

When we went to the lounge they told us to go into the main lounge and not the full business class section, later they told me that Lufthansa wont pay the full fee to alloq the business class passengers entry to the nicer sectikn where all the other airlines nusiness class passengers go into. Very poor arrangement.

Delayed over 2 hours. Bring your own snacks or prepare to pay. No entertainment and no plug plugs for charging.

Not what I expected for the last leg of a $5100 business class experience. Boarding was a nightmare. The flight was delayed and I had to keep checking my email to ensure I was at the right gate since the airline or the terminal had no clue until 15 mins prior to boarding. Food was gross, limited drink options.

Flights scheduled with impossible connections - Lufthansa apparently believes it takes 7mins to change terminals, go through passport control, re-clear security and walk 1.8kms…..and everything will work perfectly (which it never does at Frankfurt). No staff on hand to assist with transfers on delayed flights. No transfer guidance provided by app. No compensation offered for 6hr delay to connecting flight.

Crew were professionals. However, the plane seats are too small -essentially there is no space to move around which for so many hours is almost inhuman but certainly unacceptable. Same with the bad quality of food and the fact that you need to purchase Wi-Fi

Crew were friendly and very helpful Plane was clean and the legroom is standard. Overall a good flight, no complaints.

It was a very full flight, makes it harder for flight crew.
