Crew was great, service was good, flight went well. Originally, the flight was advertised with WiFi… including during check in… and nada.

Aegan Airlines compensates for its outdated business-class seats with excellent food and onboard crew service.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

For a business class, it barely met the standards of a basic economy on most carriers. The seat would barely recline; no pillow or blanket unless you ask a crew member; no leg rest (at least in the 1st row). The crew was friendly and attentive, except for one male crew member who was very inconsiderate toward many business passengers who were already sleeping or trying to sleep, slamming the doors of the kitchen compartments. He did so twice till another passenger complained to him. Overall, business class is an economy experience except for the food.

Seats that recline. Ice for soft drinks. No charge for did drinks. Wifi.

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 crew aboard Aegean were excellent, they picked on our son’s anxiety and immediately came to the rescue to see what they could do to make it go away.

Flight had delays as always. It has been very disappointing as the last 4 times I’ve travelled with Aegean we always had delays.

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

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

Didn't make the connection as my primary flight was 3 hrs late, I had to basically beg to be put on a different airline to continue my trip otherwise I would have been sitting on the airport for 8 hrs

Very unprofessional treatment of customers - boardring on being unethical. Only cares about money and not the customer. If you use the swiss brand, you should deserve it - now swiss air doesn't deserve the swiss brand.

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.

The flight was generally good but was delayed departure meant a very late arrival for a connecting flight.

Delayed 30 mins Forced to check in my carry on luggage

We are glinting with united , but over all very disappointed

No fault of the crew, but the the rear lavatories were closed the entire flight. The front lavatories were blocked off for the first part of the flight by the food cart. Then some minor turbulence occurred so the fasten seatbelt sign came on for the second part of the flight. Heroic containment engaged! It was not fun.

Our connecting flight to the US only had around a 25 minute layover! And our flight from Seville to Zürich was delayed! Had our flight from Zürich to Washington DC not been delayed we would have missed our flight to the US. We didn’t even know it was delayed until sprinting from the A terminal to the E terminal. Our flight from Seville landed in Seville 10 minutes after our the door was supposed to close for our flight from Zürich to the US. Not cool! Several other Swiss air passengers were in the same position as us, which I could tell bc we were all running for our lives in your airport. We booked a flight from Seville to Washington DC and the time between connecting flights was not enough and that’s not an acceptable position to put a traveler in. Especially one who spent over $1000 on their tickets.

Crew members were good. Seats were packed and too tight .

There was no useful information given regarding the flight back to the UK from Tenerife. This despite the week publicised problems around the EES system and the delays caused to boarding. This aspect of the customer experience could have been much better.

Fast boarding, smooth takeoff and landing. plenty of space in seats. Excellent air-conditioning on a hot day. Perfect experience

Sitting on the last row in between the aisle and a massive person, all people going to the bathroom bumped into me including the flight attendants.

The best budget airline in Europe. Flight was on time, crew friendly and worked hard during flight and were able to meet our needs. Only downside (not the airline's fault), there were no rear steps.

It was transportation nothing more. I will give a positive rating over Ryanair. We missed our Ryanair flight the night before and received rude and unconcerned treatment from the Ryanair customer service. It was late. We were very tired and stressed after doing our best to get to the airport. The so called customer service ladies were completely unconcerned from the start. Aside from that, the flight to London seemed to be their opportunity for advertising. No time to relax as attendants were constantly in the aisle selling. I will never fly Ryanair again!!

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 .

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)

We accidentally purchased twice the bags we needed. Our fault, but the ticket was not clear to us, and it asked us to purchase bags at checkin. When we notified them to get credit back at the airport, they said to contact customer service. We flew the flight and then contracted customer service. They said no credits after the flight has flown. Not customer service oriented at all. They know we didn’t check that many bags and kept our money for a service they did not provide. Be aware and very careful of what you are purchasing from them because they will not make it right if there is an error.

Would have liked the plane to leave on time so I didn’t miss connection upon arrival. Some pathetic excuse as to late departure bought about by easyJet incompetence

Flight map did not work. Crew was great, food was good, plane took off on time and landed early. That's all I can ask.

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.

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.

Flights scheduled with impossible connections - Lufthansa apparently believes it takes 7mins to change terminals, go through passport control, re-clear security and walk 1.8kms…..and everything will work perfectly (which it never does at Frankfurt). No staff on hand to assist with transfers on delayed flights. No transfer guidance provided by app. No compensation offered for 6hr delay to connecting flight.

Crew were friendly and very helpful Plane was clean and the legroom is standard. Overall a good flight, no complaints.

I did not like that they failed to put my luggage on my connecting flight to Athens. I was promised it would be located and delivered within 2 days but later told there was no information on its location. This caused me to have unplanned for expenses because I then had to purchase new clothing to wear on my vacation. I did not receive my luggage until my return flight home. I will not be traveling with them again.

No internet, very narrow seats insufficient room for three passengers with encroachment.

Other than problems with checking in and uploading passport info everything was great. It would be nice to be able to manually input passport info. Often while traveling the bandwidth has problems uploading pictures

Give at least coffee or juice as it is an international flight.

Tiny, cramped seats with minimum leg room and hard armrests. Basic needs like a seat and luggage came with an additional charge. Budget airline amenities with premium airlune cost. I won't use this airline again.

Generally very good. I think their service is better than some other big names I used to travel with. Their food variety is second to none - and you can place order beforehand. Their seating design is a bit awkward for service, I'd say. Flight attendants must be tall enough - long legs and arms - to reach the window seat passenger while crossing over the isle passenger. Also appreciated the variety on entertainment.

Could have used more leg room for “business class” which is basically coach with a middle seat blocked. Crew was friendly, attentive. Zero entertainment.

Generally okay. Disappointing compared to some of their competitors. My seat hadn’t been cleaned properly which was upsetting

Seats not as comfortable as I had hoped. Food was very nice, service was fine. Entertainment options very nice. Had thought the premium economy was a more plus 2-3-2 layout but it was a 2-4-2 with seats not as wide as I had expected.

I flew four flights on British Airways within two weeks. I was unable to download the boarding pass to my phone for any of the four flights. I could check-in for my flight but the system would not give me boarding pass. I tried multiple ways and multiple times. I discovered many other passengers also had the same issue with their boarding passes. No explanation or acknowledgement by BA.

The plane was a long way from departure lounge. The plane looked tired but got us there.

Lovely big plane. Excellent take off and landing. Cabin crew were so nice. Flight in time no delays

Our flight BA638 was cancelled with very short notice. It was supposed to depart at 7:25am. We had left Chichester at 3:30am in order to make the flight, and we were notified of the cancellation while en route to LHR. We were told the cancellation was necessary because a plane had not been scheduled to be at LHR for this flight! We were rescheduled to BA636. This flight was supposed to depart at 11:00am but didn't actually take off until ~12:30pm. Consequently we arrived in Athens several hours late, missing out on half a day of our sightseeing time. We had booked transport with MyTransfers to pick us up at the Athens airport and drive us to our Hotel Adonis. I was unable to get a refund for this service because our flight was so delayed. They required 24 hour notice of pick up time changes. I instead had to pay for a taxi at the airport. I have tried to fill out a request for compensation online but have been unsuccessful. How can I get help for filing a claim?

It was ok but not at a business class standard No entertainment system available which is poor for a 3+ hour journey Food was ok and service was good though

Late boarding with inconsistent excuses. Bulk head seats were very small and uncomfortable. 1 tiny candy bar and a water were only food provisions. Food for purchase was unavailable.
