The only issue was a short window to make my connecting flight, and nobody to assist me in finding my way to the next gate.

The only issue was a short window to make my connecting flight, and nobody to assist me in finding my way to the next gate.

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

Flight was late, boarding totally chaotic, seat uncomfortable, food good, attendants and pilots good.

Priority transfer bag left behind in Amsterdam causing extreme difficulty and inconvenience on arrival destination Athens

We had issues with upgrading our seats. The flight itself was fine.

So terrible. They would not rebook me for a flight until 2 days. I had to spend so much money to get my own flight. They were rude and not helpful.

Flight was delayed for 4 hours and they misplaced my luggage too. Appalling.

I was pleasantly surprised with the whole experience. Thank you

There were multiple delays and the food was poor. Better food.

Liked being hydrated. Carryon weight was limited for cold weather clothes that are heavy... could test to improve if possible.

Thank you to the cordial crew and good hydration throughout the flight, food was good too. Carry ons usually weight by themselves so it does reduce option for cold weather clothes that are heavy, so carryon weight is tight.

United Airlines flights serviced by Swiss Airlines provide for zero communication with Swiss Airlines almost impossible to contact Swiss airlines to make seat selection, upgrades or changes. I won’t do that again if it can be helped.

We were very impressed with Swiss Air. The service was exceptional. Unfortunately, we had a baby behind us that screamed for hours. , It was a nightmare, though I completely understand that it was not Swiss Airs fault.

The two meals were plentiful and excellent. The drinks were continuous. Thanks, Crew very polite; however a bit "hazard" at the end as they were rushing us off; to prepare for the cleaning team and next flight. Baggage from Berlin was delayed; however through the apps etc; they kept me aware and informed.(.did receive my baggage about 36 hours after my flight arrival). Good experience; thank you.

Horrible flight attendant in back of economy that screamed at me, have already reported to United. Horrible food - for Gluten free, why would you assume the person is vegetarian? I was served some kind of horrible curry bean paste and multiple cold rolls and soggy vegetables with no seasoning... um no!

I was at the airport on time , I checked in my luggage . The plane was delayed and the gate was change. The flight board did not give information . I did not get chance to fly. I am going to make a claim for it

Our flight from Frankfurt to Newark was diverted to Boston. Lufthansa just dumped an entire 747 plane full of passengers in Boston with no support. No help with hotels, and telling us we would have to find our own way back to Newark or to our final destination. What a complete mess. The Lufthansa agent at the Boston airport would not help, nor would any Lufthansa agent via phone. Soooo angry!!!

Never flown with LH before so all in all wasba good experience. Also good to know that approx 24hrs prior the flight opens up for being able to organise the seating free.

It was a short flight, no real service (which is okay). Very bumpy because of weather.

I'm Canaadian. I hate Air Canada. I used to give them a pass on their international service. No longer, They suck across the board now! Old planes, exhausted staff bad food and shitty entertainment. Your seats need reupholstered! Start with that...

Good experience. Food was great and passengers helped rearrange seats so our family could be seated together

Great flight. Left on time, not very crowded. Quiet and the right temperature.

No eye patches , socks given out for overnight flight! The snack on the short haul was a cube of chocolate! The seat was uncomfortable for a long haul - not enough cushioning!

I paid a lot of money for seat selection and was miserable for flight duration

The trip itself was good. I have given only good as rating, because my first flight has been cancelled by a different airline and that caused disruption in my trip. I spent over ten hours in Luton airport and that caused me high tiredness, sickness, because of the very early initial trip. easyJet staff has been professional and friendly.

Very pleasant crew, working hard on a full plane. Delay by a broken seat. However crew made back 60% of the delay.

Delayed and then further delayed with no announcement made so that all the passengers (who were standing in the jetty) could hear. We stood there for well over 20 minutes. We were further delayed through weather but no one explained that to us until the pilot made an announcement when finally on board

easyJet need to ensure that whether pre-booking seats or not children aren’t split from their parents the crew spent the majority of boarding asking passengers to move to accommodate two families. Surely the system identifies minors on a booking !!!!! It was all very frustrating to watch and caused delays which I’m sure cost easyJet more in the long run rather that automatically allocating families with minors seats together automatically.

As you would expect from a budget airline Left and arrived on time, no frills, not even a glass of water offered But you get what you pay for

I had an emergency escape seat. The attendant gave the extrA briefing to my side of the aisle but didnt direct it at all to the other where my wife was sitting

Boarding great. Didn’t eat or drink so can not comment.

Total jobs worths over carry on bags, charged £96 extra for bags that were clearly hand luggage

3 hours delayed Don’t understand why when you have paid for ‘speedy boarding’ they call you forward to then make you stand fir another 20 minutes in a confined space before boarding the plane.

The pilot did everything possible to make up the 35 minute delay. His communications were honest, prompt and positive throughout.

We were told to check our bags at the last minute, and the communication was poor.

Lost our luggage in Heathrow. Showed up 3 days into a 7 day vacation. Very inconvenient and disappointing!!

My luggage never arrived to Zurich. They can't confirm when it will arrive

Late again. 3 out of 4 late. One cancelled flight and one lost bag.

Charged an extra 65 pounds for overweight suitcase, Not told how much overweight but had no choice but to pay the price. Compare to Delta Airlines where I flew internationally a few days before with this suitcase and no extra charge by Delta. Comfort was horrible. I am just under 6 feet tall, and good that the flight was only 1 1/2 hours, because my knees were in the seat back in front of me the whole flight. I felt that my knees were part way up to my chest. No reason to have the seats that close. I will say to the positive was the flight crew, very friendly and efficient.

The flight was delayed as they were waiting on catering. Catering. Was eventually delivered but they still had no food. No meals for us in business class - just a bag of nuts.

Our luggage is missing. We are at the Hotel Gran Via in Barcelona

my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.

The flight was on time and the crew very professional. Everything went as expected and I will use BA again for this trip.

We paid to have overhead carry-on baggage. When we got to the gate we were told that our carry on bags would need to be checked and go below because the flight was full. Notably we were nowhere near the last people to board and about 30 other passengers also had to check their carry-on bags. Other than that the flight was fine.
