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.

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.

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

It was a short flight. It did leave about 15 minutes late but other than that everything went well!! There was no food service or entertainment so can’t comment on any of that.

For a quick trip to athens they did a great job plane was spacious, and we boarded quickly.

it was hard to find the check in at the airport no signs food was average

Water bottles could be in more sustainable packaging than plastic bottles

Best international flight I have had in a while! Far superior accommodation, services, food and general experience compared to U.S. airline companies.

Very nice crew and great food. Easy to board just wish the flight could be shorter or seats more comfortable or more room to walk around when you get cramps in your legs from sitting so long. Crew was great and attentive and really was good food.

Horrible flight. First delay in boarding of approximately 30 minutes. While in the plane, the flight attendants huddle and we get an announcement that the crew's legal time was exceeded, that they don't have replacement crew and that they will need to cancel the flight. One would think that they would know that their time was to be exceeded BEFORE boarding. Took for ever to deplane. Then we were told that flight would not be cancelled but gave us a departure time of 21.15, which of course was not fulfilled. Arrived in Valencia, luggage took 30 minutes to arrive. Absolutely unacceptable

Well it was a 2h delay flight so that said it all. With very little if any information. Boarding took for ever with long waits at the terminal and then in the finger. To top it off and increase the delay we had to take a bus in Zurich. A trip to forget

The flight did not take place because the flight was canceled and I still have not received a refund for the flight.

At the boarding gate, passengers were offered the option of checking in their carry-on luggage, as the plane was full. However, they failed to specify that they would not be dropping it off at the exit. Instead, everyone had to wait over 30 minutes at the airport carousel, and to everyone's surprise, not even the carry-on luggage, but the checked luggage, was the first to arrive. An hour later, we finally collected our bags. Lesson learned: I will never check my carry-on luggage with Swiss Air / Helvetic Airways again.

Not good. We returned on united airlines and the food was horrible.

The seats were so close together, when the man in front of me put his seat back, the screen in front of me was 9 inches from my face. There is no way to lean forward if I needed to pick something up. It was pretty uncomfortable for a ten hour flight. I was very surprised.

The food was good. Most the staff was pleasant. The flight would be drastically improved with WiFi on a long international flight.

Boarding and disembarking were smooth. Not offering free water was cheap ... I've never encountered that before on a flight.

Boarding could be better. To get through your gate but to be stood in a corridor for 20 minutes is not great.

The plane was postponed for over 2.5 hours, which meant that all four of us missed the check in time for our ongoing trip to Melbourne. We had to buy new tickets for 4 people as we had to forfeit the ones we had. The cost was really unfair. i understand that it was snowing during the first leg of the plane for that morning. Surely the cost could have been shared by the airline and not all by us. I could have bought insurance - but you can see how much I travel. I will need to chose more trustworthy airlines.

Queuing for quite a while despite using the "speedy boarding".

Would not advise EasyJet for a 5 hour flight…small plane and hence a lot of turbulence. No inflight entertainment so struggle to pass time in cramped seats. We also fell victim to extra charge for our cabin bags, although bag dimensions were ok, but the handle was rigid and slightly fell outside their testing cage!!….never again will we fly with this airline and be party to their scams for making money!

The food and so are to expensive and old . Crew whas not very friendly . Apparently some other passenger can just Push through the waiting people to board while almost punching me and a father with a child down the stairs. Its always something with easy jet . The seats of row 26 where lose . And for a guy of my size there is absolutely no leg room at all .

Nice to fly out of Orly smaller easier to navigate airport. Being able to receive boarding pass well in advance of trip was comforting to know all travel was in order.

Liked. The check-in was pretty quick as they had 5 desks working.

Generally a good experience except for boarding in Naples on the flight back to London. We were all standing around for at least 20 minutes maybe longer as there was no seating.

Seats, WC,sizes for today's generation adults, and if technical problems arise a complimentary coffee, water nice for waiting one hours, the rest is perfect (pilot and cabin crew)

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

Efficiency of staff, and comfort and cleanliness of aircraft was all great. Maybe a hot drink without payment at that time in the morning would be good!

Insulting. Lufthansa flight from Munich to EWR had us getting our luggage when we were told in Florence that it would follow us to Indianapolis. It did not. Then very slow security in EWR caused me and three other passengers from Lufthansa flight from Munich to miss the boarding closure. Behind me were two elderly grandparents and their ten year old grandson. We were all refused entry on a plane to Indy that was still at the gate. The doors had not even closed inside the terminal yet. No apologies or compensation offered. Not even a meal voucher let alone a free hotel stay for our inconvenience. I m not sure what the other three passengers behind me did ( they were elderly with a grandson, recall), but I stated 12 hours overnight in a chilly EWR airport until next flight to Indy at 850 next morning.

The plane was late (as was my flight out from Birmingham the day before)

The flight was delayed by an hour. Made the connection uncomfortably tight.

When we went to the lounge they told us to go into the main lounge and not the full business class section, later they told me that Lufthansa wont pay the full fee to alloq the business class passengers entry to the nicer sectikn where all the other airlines nusiness class passengers go into. Very poor arrangement.

The boarding system was all bogus - employees at the boarding gate were not sound like proffesional or may be possibly rational

Delayed over 2 hours. Bring your own snacks or prepare to pay. No entertainment and no plug plugs for charging.

Pathetic service by underpriced, please call me back at the earliest

Not what I expected for the last leg of a $5100 business class experience. Boarding was a nightmare. The flight was delayed and I had to keep checking my email to ensure I was at the right gate since the airline or the terminal had no clue until 15 mins prior to boarding. Food was gross, limited drink options.

I was unable to board this flight because of visa changes that I was not alerted about and I’ve been unable to contact Kayak to obtain a refund / credit anything.

My touch screen at my seat wasn't working, the films BA advertised on the website for this flight were not available, and the plane was a little dated, food was good and the staff were good, just let down by the aircraft facilities.

Did not like the seating configuration at all with 2+3+2 in business class. Lacking total privacy and comfort

Check-in experience, for business call please provide a premium experience

Lost my luggage, ran out of food choices in business class, ground crew was completely unapologetic.

Excellent. The crew and flight were great. Checking in was easy and everyone was very helpful.

Late. And service was very slow - passengers sat for well over an hour with dirty trays etc surrounding them

Entertainment devices on A380 need to be fixed, the seats might do with updates.

I like everything about British Airways. Excellence. Perfect. Exquisite service.

The plane was dirty the food was awful and the boarding process took too long
