I feel the ground staff could benefit from further training to enhance the overall guest experience.

There was nothing wrong with Aegean. We were very confused about whom to contact, since we booked with Kayak, then got shoved over to Underpricer and some other agency.

Cabin crew were absolutely fantastic. Couldn’t have been more helpful to me and my twins and family. Great crew!!!

Highlights were the food and wonderful staff. Airplanes were exceptionally clean.

Aegan Airlines compensates for its outdated business-class seats with excellent food and onboard crew service. Launge was also excellent.

On every Aegean flight it seems, they ask people to check in carry on luggage. That seems to happen less often with other airlines for some reason. The food is very basic for a full service airline. We do not need a meal with trays, but something of higher quality (even just higher quality pies) would be better. The cabin crew was very nice and professional, though.

Seats that recline. Ice for soft drinks. No charge for did drinks. Wifi.

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 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.

Super helpful personnel. Airbus 320neo, new and comfortable plane. Could offer also tea and sparkling water as courtesy.

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.

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.

NO HELP FINDING PROPER CHECK-IN LINE; STAFF PERSON WE FOUND WITHIUT ANY SIGN WAS ACCOMADATING

Lounge poor. Food poor. Airline service just ok. Business class seat not comfortable.

The flight was generally comfortable. However, it was the smallest bathroom on a plane that I have ever seen.

Business class seats were harder than expected, and lie flat we're not very comfortable. Less expensive than other business class flights, and much better than flying economy. The crew was excellent, as was the food.

Boarding was slow and getting off the plane took a long time. The crew did not have enough water for the trip.

Boarding was a bit chaotic, planes were on the oldish side. Otherwise, very nice flight. Would fly them again.

food was terrible on the plane, bring your own food, its not worth eating.

Turkey slices for breakfast. What happened to eggs, bacon, and sausage? The TV shows could’ve been more comprehensive as well as the movies.

The in flight meal was absolutely delicious. One thing I noted was that the meals weren’t just prepackaged tv dinner style options but were actual prepared meals you could tell were cooked that day in a kitchen and individually packaged for the flight.

Special AVML was terrible Movie choices were quite limited Otherwise excellent
