Pros: "Food and drinks!"
Cons: "Nothing, it was great"
Read more about Aegean Airlines
Pros: "Food and drinks!"
Cons: "Nothing, it was great"
Cons: "There is no free beverage service, let alone snacks or meals. Some tickets do not allow you to pre-book a meal and there is no way to buy a hot meal even in a 12-hour flight.leg room is a bit small and carry on restrictions are getting lower all the time."
Pros: "The crew"
Cons: "The kosher food"
Pros: "Crew was amazing—efficient and kind. Loved the seat space"
Cons: "Nothing. All good"
Pros: "The best landing of a commercial aircraft I have ever experienced in my 74 years and in half a century of flying across the globe, took place in arriving at the Madrid airport with this Aegean Airlines flight. I had to ask the airline hostesses the names of the pilot, and they were two pilots flying"
Pros: "Food was amazing"
Pros: "Good on business class was amazing and the staff was always ready to help with any questions."
Cons: "Flight was delayed twice and because of that the airplane was not as clean as it should of been"
Pros: "Organized"
Pros: "Ground crew and cabin crew were very helpful and efficient"
Pros: "I did not make this connection due to delayed first flight and the most poorly organized and staffed airport!!!"
Cons: "Getting reimbursed!"
Pros: "Aegean is a fine airline overall"
Cons: "I had a carry-on bag, no problem on the flight from Madrid to Athens; but on the return trip they weighed the bags of some passengers, and when mine was over the limit -- which, however, was not indicated in the baggage restrictions -- they charged me 60 euros and I had to check it right there."
Pros: "The crew was nice, friendly and helpful."
Cons: "There wasn't an autobus ready to take us from the main terminal in Athens to the plane on the runway."
Cons: "Boarding could have been handled a bit better. We were told our suitcases could not be carried on as they were too big, but we saw other passengers with luggage just as big but they got to carry it on. They didn't charge us for checking the bag which made the issue less irritating."
Pros: "Crew was helpful and polite"
Cons: "Apparently Aegean has stopped offering candy before take off. That's a pity as this was a nice (and presumably low cost) way of differentiating from other Star Alliance airlines. Food was mediocre and there was no in flight entertainment."
Cons: "Horrible food"
Pros: "We didn’t crash."
Cons: "Everything else."
Pros: "Seats and the leg room"
Cons: "Vegetarian food"
Pros: "Great crew"
Pros: "The food, crew was nice and polite."
Cons: "Didn't have any entertainment"
Cons: "Again the airport. Its not the airlines fault, but to have ONe set of toilets in a whole airport wing is unacceptable."
Pros: "Nothing."
Cons: "I'm a photographer on a 3 week trip. I have luggage. Unless you take the ferry, there are limited airline options to Cyclades. Aegean really doesn't want you if you have luggage. Felt like I was being scolded. True, I'm trying to be frugal and avoid a big investment in shock-proof luggage and/or checked baggage fees, but as long as it fits under my seat, what's the big deal? I'm sure I easily weigh at least 70 pounds less than the person sitting next to me, so the extra 4 kg in a backpack that I (female) can personally carry shouldn't be an issue. Then, there's no jetway. You leave the gate to board a bus that takes you to a plane on the tarmac where you must climb a rather large flight of metal stairs. Reverse direction, It takes quite some time and a few crew members to assist those with disabilities to deplane. All the time the rest of the passengers are waiting in the bus to get to their connections. Would only ever fly this airline again if it was the only option to get where I want to go."
Cons: "I arrived just before the hour an hour before departure for a 6am flight, which is in line with their 60 minute policy to find the counter closed. I spent another 25 minutes running around the airport trying to find someone to assist including a ticket agent to adjust my flight. Only to be told I couldn't get a flight out until the next day and I had to pay more for my original ticket for it. I contacted customer service and their response was a simple copy and paste of the rules which I was well aware of (apparently I should have really been there 90 mins before and not 60 according to the site). I only booked with the airline because it offered an 8 hour layover in Athens...a chance to see a bonus city. There are plenty of other airlines with more flexible and consistent policies. I have traveled the world on many airlines and have never had an early check in counter close or to have to chase down a representative to get service."
Pros: "Seats. Food"
Pros: "The employees were very helpful and friendly. Food was not worse than what one can expect of an airline (about as “good” as a US airline’s, which is not a high standard to beat). The plane seemed recent and clean."
Cons: "The major problem was the lack of detail on their luggage policy. I am sure they can show the text clearly warning me about the fees for bringing a piece of luggage per person, but I missed it. Therefore, they charged me $35 per person for their registered bag. That’s probably how they “beat” their competitors’ prices. If you include the fees in your calculation, this might still be a good option, but make sure that you read the fine print, or be prepared to pay as “extra” what many airlines offer as basic."
Pros: "This flight was great."
Cons: "See above"
Pros: "Accurate times"
Cons: "Night travelling"
Pros: "Amazing Crew"
Pros: "No surprises. Routine flight."
Pros: "The crew"
Cons: "The changes in gates"
Pros: "We were given a meal"
Cons: "The meal wasn't very good"
Cons: "I did not understand flight attendants in english because of their bad pronunciation and I did not know what their saying all flight."
Cons: "I had round trip flight with Aegean airline from Santorini to Athen and Athen to Santorini, Both flights had DELAYED FOR ONE HOUR!!! My gateleg table was broken on Athen to Santorini flight so I ate my lunch in a hard way!!!!! On the way back after one delayed finally we arrived at Athen airport and I had two more flight to caught. when I got my luggage do the next flight I realized literally my luggage was destroyed!!!!"
Cons: "Procedures for handling sick elderly passenger. One crew member should take initiative and deal with sick person and handle calling for a doctor on board ."
Cons: "1 hour delayed"
Pros: "Very bad"
Cons: "All the team"
Pros: "Friendly staff, clean airplane"
Cons: "No entertainment"
Pros: "I love airlines where you can drink wine with your food."
Cons: "Everything was good."
Pros: "Clean, smooth, on time"
Cons: "Food was not interesting"
Cons: "They charge me on my two flight about 100 euros for my bags that's the worst , never had that and this is my first and last time I used them"
Pros: "Quick smooth and efficient with two exits at landing."
Cons: "I hated that I and 10 ither passengers were told to RUN! i had left London, so my attite was heavy, and here i am running through the airport. It was exhausting. Why should we have to run when the intial connection was 45 mins. Because one plane with the SAME airline is running late and gives us 6 minute's to get to the gate, that should not be any fault of the passengers. Radio the other flight and have them hold. I got an email that the gate changed TWICE. the airline employee did not get that memo at all. So we were raced to the wrong gate even AFTER, I mentioned the gate change. A real frustrating experience all together."
Cons: "Was perfect"
Pros: "Great service nice food comfortable flight"
Cons: "Nothing :))"
Pros: "The flight was great. The staff was nice. Everything was great!"
Cons: "I didn't realize that we could of brought on our bags for free."
Cons: "The staff in Athens airport, at the ticket desks, were disinterested, and actually rude. Bad impression."
Pros: "I was surprised about the food, it was exellent."
Cons: "The ticket didnt specify the type of economy class so we had to pay for extra baggage"
Pros: "The flight crew were very friendly and gorgeous!! And short flights!!"
Cons: "The boarding process was a little unorganized."
Pros: "Nothing!!! I wait for 21 hours in the airport for a 45 minutes flight!!!!!!!!!"
Cons: "We lost a day and all the expenses such as tours, hotels, etc. that we payed before and nothing was covered by the airline, we were just offered to get our money back from the flight but they never gave us a solution. Some of the people in AEGEAN airlines were extremely rude and had no empathy for us, it was an awful day!!! because we had no sleep cause we where there at 2 am in the morning cause the flight was at 5:15 and we did that because we wanted to be for the whole day in santorini so you can imagine how frustrating and upset we were, they just gave us a snak for 6.50 Euro and 10 hours later We literalaly had to figth for our Food, We will apriciate if youu can do something about it or get us a refound, we where 3 people: ana Marrufo, Estefani Escoffie and pamela Ramayo"
