Aegan Airlines compensates for its outdated business-class seats with excellent food and onboard crew service.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

For a business class, it barely met the standards of a basic economy on most carriers. The seat would barely recline; no pillow or blanket unless you ask a crew member; no leg rest (at least in the 1st row). The crew was friendly and attentive, except for one male crew member who was very inconsiderate toward many business passengers who were already sleeping or trying to sleep, slamming the doors of the kitchen compartments. He did so twice till another passenger complained to him. Overall, business class is an economy experience except for the food.

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

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.

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.

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

Take off was almost an hour late Baggage arrival was 45 minutes late this added 2 unnecessary hours to the trip

Basic charter flight, ok for 2.5 hours. Cabin crew could have a better attitude.

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.

It was a short flight so food and entertainment wasn’t necessary

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.
