Every one was attentive, the food was really very good . All and all was an excellent experience .

There was no enterteinment onboard. Food was good, and service too.

It was a short flight. It did leave about 15 minutes late but other than that everything went well!! There was no food service or entertainment so can’t comment on any of that.

Not good, the seat was broken and the middle seat table was not lowering, no option on the food, despite the business class wasn’t full. In the menu offered they had fish or chicken, no chicken available when was my turn (seating in raw 2!)

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

Moved me away from my family and refused to fix it.

I noticed the crew was so much nicer and friendlier. It would be nice if British Airways would serve soft drinks during the flight

Must have had an elderly tour on the trip. Plane boarded via tarmac and had both front and tail stairway access. We waited about ten minutes at the rear entrance while elderly folks entered the forward access and walked all the way back to last rows of the aircraft! We could not access the row until every one of them finally reached the final rows. There should have been an agent directing folks Forward and Aft based on seat row. It was comical.

The airport experience at check-in, just to drop a bag, was horrible. The were two agents working, two watching. We stood in line for just short of one hour. I asked the agent if this were normal and he said, "Well, yes. Just two computer terminals." No apologies. BA needs to fix this ASAP. Meanwhile, I've moved BA to the very bottom of my booking list.

Good shuttle to Europe. Face check boarding needs overhaul. 2 stations for 200 people and still with passport check. Why have both? Why is this now slower than 5 years ago?

Tickets get checked 4 separate times by different staff, would save time if only the person at the entrance and the person who scans the tickets checks them!

I have always been pleased with their service. Would not change a thing

Both flights Heathrow and to SFO were delayed significantly. Walking up outside steps to aircraft with suitcase was a challenge and I am a healthy 63 year old!

Why don't they board from the back of the plane to the front. We have to move by all the people and their luggage to get to the seats.

Seating and food was the worst we have experienced in 35 years of traveling for both personal and busines .
