Bulgaria Air should stop using buses for boarding if possible. It is very inconvenient and delays the departure

Easy check in. Hot snack with wine if desired. Then chocolate, tea or coffee. Altogether excellent.

Seats are quite small, but due to the plane being empty we were aloud to switch seats to have more room

The water was handed out as we were entering the plane, instead of when we are set down and our hands are free of luggage. There was absolutely no food offered from Sofia to London, except a low quality chocolate, which was not delicious. The flight between London and Miami was ok, as far as service and food, but it was absolutely freezing, throughout the whole aircraft, especially in the back seats, I had to cover my head with a scarf, besides using the blanket and still I was feeling extremely uncomfortable. The passengers seating around me shared the same opinion. We did ask for something to be done about it. The gentleman did try to adjust it, but the effect last very short time, and towards the end of the flight it was extremely cold and blowing strong again ….

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 flight was full. The young man in the seat in front of me had reclined and I asked him to put the seat up just a bit because it was encroaching my space quite a lot. Turned out he couldn't because the mechanism was broken. The choice was all the way up or all the way down, no in-between.

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.

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.
