Internet not working during the flight - what a big miss!

Aegean Airlines was great! Great spirit, very helpful and efficient. Overall Aegean Airlines was a great experience.

The flight was excellent but the onboard WiFi wasn’t working.

The seat was hard as a rock. Business class seats were coach seats with no one in the middle. Service and food were excellent.

The crew was awesome. There was a school group of about 60 14 year-olds. The food is standard greek fare, Baklava was pre-packaged like it would normally be sold in a vending machine, and it was the highlight of the meal. Plane was in great shape, and seating was like a any A319 you would experience at a national-level carrier (i.e. not like Ryan Air). Like many European airports, they bused us to the plane, so the process of boarding groups is useless, and not well understood by infrequent travelers.

Departing from the Parikia apport on Paros was chaos. It is a 3rd world airport, and my home has more square footage. Olympic Air has several instances where there are less than two hours between flights leaving Paros. Further, there are two airlines at the airport, so airport resources are limited. With only one check in desk for each airline, the folks who are getting on the earlier flight are the only people who are able to check in. So, don't get there too early to check in. Also, the airport waiting area, after you go through security only holds about 1/2 of a plane's worth of people. So, the security line also has the same restrictions as the check in desks. Depending upon what time you get there, two queues will extend into the entry road. If your plan departs within the hour, go up to the front of the building and check to see which flight they are checking in or running through security.

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.

Old plane, sold out on snacks, just trashy seats..broken..etc

Good flight. Only negative was the bus journey from plane to the terminal. Didn’t exit t this either BA at T5

Nothing! They canceled our flight to Greece the morning we were supposed to leave and offered us another one 5 days later (for a 9 day trip). They said it was an “operational decision”! Yeah a 777 that was 2/3rds empty, so they probably sent it to the Middle East to make a fortune getting people out of there!!

WiFi wasn’t available to economy until the end of the flight.

Boarding crew were extremely rude. At check in, I showed a medical note from a surgeon stating that I had a medical problem that caused me to end up in an emergency room. The surgeon requested that I get an upgrade so I can travel back home comfortably since I was in a lot of pain. I was alone with my daughters (9 and 14). They made a huge deal about giving me seats although there were so many empty seats in business. Finally, I paid a hefty price for it and the seats were exactly the same as in economy cabins but not as good because there was a forced tray in the middle seat that I couldnt even lift so I can lay down.

Very good staff members with sincere passion and responsibility in their job.

We were unable to check in on line with no explanation! Despite arriving at the airport 3 hours before deprture, my wife and I had no allocated seats and ended up being seated seperately. This is unacceptable! We were both ib the middle of the centre of the aircraft, despite having previously requested an aisle and seat next to it when booking and having been an Exec Club member for 25 years - so much for loyalty! The seats were extremely uncomfortable for such a long flight. I fly a lot and these were, by far, the most uncomfortable seats I've had in many years. It was all fine until we arrived at LHR where we got off the plane quickly, but then had to wait more than 45 minutes in the baggage hall for our bags to arrive, despite the fact that some luggage was already off when we got to the carousel. After 14 1/2 hours flying, this is completely unacceptable and ruined the experience for us.

Very please with the seating that the Kayak staff booked for us!

I liked the movie selection and the speed getting the luggage. I did not like the fact that for premium they did not have a personal kit with toothpaste, I travel all the time in premium economy and bussiness and althought the kit might bot be the same at least you have the smalles kit in premium economy. I did not like either that because i was in the last row of premium economy nothing made it to my seat. They run out of the food I wanted ( it is a surprise because there were only 6-7 rows. They would run out of orange jouice were thy were passing water/orange juice around, they run out of some alcohol. I am undertand running out of it but I don’t understand why mot getting kore. The service I received in row 11 was different from the service in rows 7,8…. Also the screen on my tv was broken. It did not respond to touch. So, in conclusion, if I compare my flight going to Europe with an American airline plane in premium and the one with British, British expereince was significantly much worse. This company is declining fast.

The crew on the flight were not particularly pleasant and fluid restriction was an issue. I was not allowed to fill my water bottle. Crew didn't check on passengers other than meal service.
