This is my first time flying Aegean Air and I had a great first time experience. I will fly this airline again.

There was not any food and I didn't use the entertainment

Just ok. No much of a great travel experience. If you need point A to B they are ok.

Η πτήση εμφάνισε μεγάλη καθυστέρηση και λαμβάνοντας υπόψη το γεγονός ότι επρόκειτο για την τελευταία βραδυνή πτήση, ήταν ιδιαίτερα κουραστικό για τους επιβαίνοντες.

More leg room, great if crew could move people before flight (ie if 3 in a row, offer to move 1 or 2 to an empty 3 seat row rather than let people move themselves after takeoff

Very bad experience during the boarding, the Aegean employees were very rude, and impatient with the passengers

Θα πρέπει να υπάρχει εστίαση στη γρήγορη και εύκολη επιβίβαση/αποβίβαση

aegean took off late, which made it impossible for us to make the next flight on air canada, we all ran to the terminal, the plane was still there but the air canada folks wouldn't let us board because they said the door was already closed. they told us we had to go all the way back to aegean desk to arrange another flight.

different entrance during the boarding for gold members and business class

Our flight was canceled after we paid in full and began making further plans. we were refunded only around75% of what we paid! I strongly recommend against ordering Aegaen Airlines!

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 ….

Cons: "Staff seemed confused and would not let us seat at our assigned seats which we picked in order to accommodate our baby. Instead they put us in an even worse spot and decided to ignore the people that took out seats and left them be."
Cons: "Them actually refunding my flight when I couldn't legally travel due to COVID lockdowns."
Pros: "Nothing"
Cons: "To add food and to patk the plane at the linkway"
Pros: "It was a direct flight to my destination"
Cons: "Check-in took 1 hour and 30 mins. Single Check in desk for economy and business, long line. Flight went late by 50 mins on departure"
Cons: "I wanted to note that while screaming at gate D1 the stuff was beyond horrible. Lazy to talk, a lady who was on the screaming machine kept making nasty comments, really inappropriate addressing foreigners and people who speak Bulgarian. I found it highly disturbing, border line harassing. You can’t work customer service and be such a nasty grumpy person. Everywhere in the world that attitude won’t be allowed, or sanctions must apply. The lady who was collecting money for the checked bag was extremely rude and lazy. Almost kicked me out for not paying for my checked bag online. Excuse me? Why is she there then? The flight was fine. However, the flight attendance slipped the last 2 rows with drinks. Please make sure that the people who work at Sofia airport get some kind of basic human training. Unfortunately, they do not wish to make you feel welcomed or cared for."
Pros: "fast trip, clean plane"
Cons: "Was a bit different to get on a bus to take you to the actual plane"
Pros: "Nothing. Bulgarian Airlines is a fifth world company!"
Cons: "Everything! The flight from Sofia (after flying in a plane that looked like a bus from the 80s), was late over two hours. Bulgarian airlines lied to us in Sofia that we would be rerouted on other airlines and find out our new tickets only at transfer desks in milan. There were NO transfer desks"

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.

A coffee at 7 am in the morning would have been nice.

We hope that soon Sky Express will have the entire airplane fleet refreshed. More new airplanes to fill the gap and expand further direct flights to new airports. Crew acts responsibly and kind, which is even more important at this pandemic period.

I was going to miss my connecting flight with sky Express also and the people in the office said they couldn't help me book another flight for the next day, but that I had to wait until anthens and go their office to help me. Other people on staff were friendly though.

Cons: "I had to pay extra for baggage, I had baggage on the booking, but upon booking it was only for 8 KG, and need to purchase more, The baggage cost was almost equal to the ticket, needs to be addressed on the home page, I pick with baggage and then booked the ticket, needs to show that it is not the same baggage as other flights, comparison is wrong."
Cons: "Only allowed 15kgs even though we had booked for 23 on the way to Santorini. Not sure where this discrepancy occurred but had to pay for extra weight."
Pros: "Crew and flight attendants were highly professional. Arrived early; short boarding time. Airport was clean and easy to navigate. Good places to dine."
Cons: "The web site is difficult to navigate, including the determination of luggage pricing and seat assignments only available at check-in."
