Ove Aegean Airlines! Used them for several flights over past 4.months. never flown w them before but will certainly use in the future!!!

A thoroughly enjoyable experience in business class, which we “won” in the airlines lottery In exchange for a relatively small deposit. The breakfast served at the beginning of this three hour flight was absolutely phenomenal. I would be tempted to fly Aegean airlines on a transatlantic flight in light of this experience.

Was grateful that this flight was held for us as we were late from our prior flight.

Our connecting flight from Barcelona to Athens was late and it appeared that we would not make the connectimg flight to Telaviv. The plane ended up waiting and we made the connection. The airline redeemed itself.

Lovely experience with Aegean. The crew felt with some extremely rude customers with professionalism and poise. The flight went off without a hitch and even landed early!

When a flight has a delay of about an hour it is customary to announce the passengers

Nice business class service for shot flight. Especially when the free WiFi works

I liked bumping up to Business for less than full price. Also the option to choose your own meal online. In retrospect I would have gone with the standard meal option, but c'st la vie. Overall pretty standard flight, got good views of Greece as the sun rose. That's about it.

It was a short flight (2hours) so the tiny, tiny seats were somewhat tolerable. People with long legs had their knees up to the chair in front of them, quite uncomfortable. I was pleasantly surprised they served a small meal which was quite good. Staff were all great.

Boarding in BCN was really poorly managed. No communication from airline staff and no signs as to what groups line up where. It was just guessing. There were delays that were also not communicated so everybody was standing in line for almost an hour.

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.

Seriously, every airline needs to improve their boarding procedures. Even though Sky Express boarded the furtheredt seats from the door first, it was still disappointing that it took so long to board.

Cannot take it dur to the delayed first flight. Staff at the desk very unfriendly.
