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Aegan Airlines compensates for its outdated business-class seats with excellent food and onboard crew service.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

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.

Every one was attentive, the food was really very good . All and all was an excellent experience .

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.

They blocked me from checking in online and they charged me lots of money

Everything was good with Tap Air Portugal. It was Logan Airport that was a problem. The fuel system was down and delayed my 10:40 boarding. I wasn't able to board my flight until 2:00 am...after that my flights were great.

Seats had no charging ports. Our plane was rerouted to Boston and we were landed on the tarmac with no food or water for 3 hours (illegal). We then waited in the airport for 3 hours while staff had no information regarding where our bags were or when we were going to get them.

Very poor communications during flight. Our flight was diverted with no communication. We waited for hours in the terminal for word on how we would get to Newark No chargers on the plane Won’t be flying them again

This is a terrible airline. Never again. We got diverted for weather and are sitting on the tarmac now for hours. No updates. No water. No food. This is insane.

Not have my bag forced to be checked when I had a carry on included on my ticket. Staff was very rude to me for asking why they were doing this. I was told there was no more room for carry ons but there was plenty of space in the overhead compartments

There were no delays. I almost lost my connection because of the new EES system

It was a game of hurry up and wait. As advised we arrived at the terminal e hours prior to boarding. We waited about 45 minutes before anyone showed up at the check-in terminal. When someone does arrive she rearranges the line and we think we are going to be checked in. Nope. She leaves and we wait another 15 min. before anyone else shows up. One person got behind her computer and about 15 min later started to check the first person in . Then one more person arrives spends 10-15 behind the desk and then she starts checking in someone. Two more staff arrive and another 10 min or so they are ready to begin checking in people. We have a 11:50 international flight and it is 9:45. And then on of the agents, closes her desk and leaves. And every leg of our flight was delayed; we waited at terminals, we waited to take off, we waited to deplane. After arriving in Porto within 10min of our connection schwduled to take off, we were told to go to the last bus. We waited on the bus (until all the other busses had left) and then we waited another 10 min or so for one of the ground controllers who wanted a ride with us but was busy with a woman who needed the handicap van. He did not help her to the van, but was standing with her and talking with hher. We were rushed through border control and told not to wait for the rest of our party only to get on the plane and then have to wait another 45 min before we were cleared for take off. The waits were not 10 or 20 minutes, they were 35-55 minute waits each time. Miraculously, we made it back only 2 1/2 hours later than we we were originally scheduled. Given the nonchalance and seaming disinterest from many of the staff, I was expecting that we would not get on until much later than that.

The crew was excellent. What I did not enjoy was the food. I have taken many international flights and this was on the low end. Otherwise the trip was fine.

Seats were the most uncomfortable seats i ever experienced on a flight to Europe from Boston. It was a waist of money in buying premium seats for top dollars. I want my money back for what i paid extra for my seats. Awful conditions!
