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

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.

The flight was an hour late leaving Heathrow. The food was mediocre. When we got to Austin, my husband’s luggage was missing. He filled out information at baggage claim. We are waiting to hear something. His name is Henry Jacob Braunig.

Only for BA because we had to get to Edinburgh at a certain time. Baggage lost, late boarding with only one person checking, again, our passports and boarding passes until the despatch controller had to step in to get us away. Will never fly BA again.

We arrived late to London, and consequently were 5 min. late to be allowed through security for our next flight. Even though dozens of people missed the same flight, BA did not radio ahead to hold open security for an extra 5-10 min. to allow people to get on the flight. This caused an additional 6 hour delay in London after waiting over an hour in Customer Service to get rebooked. They did not have enough staff on hand to help people in a timely manner. Not at all happy with the BA's customer care or customer service.

All service prior to the flight was terrible: online check-in not working, no customer service tel,, multiple airport scanners not working, A huge mess.

CONSTANT ERROR MESSAGE THAT THE WIFI COULD NOT BE PURCHASED DUE TO INABILITY TO CONNECT PAYMENT SYSTEM VIA SATELLITE. THIS HAPPENED IN BOTH DIRECTIONS. THE MAIN REASON I TRAVEL IN PRIORITY IS TO BE ABLE TO WORK FOR WHICH I NEED ACCESS TO INTERNET. .

They lost my luggage. Lady who was helping with it in Austin was rude. Not very helpful!

Waited 3.25 hours in plane only to have the flight cancelled.

The business class seat was an uncomfortable conversion of a main cabin seat well below the quality of even the budget carriers in the US. I would have never paid for business class if would have known I get the same seat as main cabin. BA has gone down hill significantly in this class of service.

More space, of course. a footrest! more room to walk. Movie selection was awful. Some good documentaries would help if the movies can't be better. The flight itself was great, crew was great.

I had a great experience on this flight! The crew was extremely helpful and attentive. Seats are very comfortable and the in flight entertainment was excellent.
