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

Short flight. Was not told if there was a kosher option for the snack.

Lost my bagage on the first leg of our trip. Not even on the transfer but on the first flight they didnt put our bagage

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.

My experience with a GNA was extremely poor. My original flight was canceled. They put me on another flight. Four hours later. They changed my seat number to the last row where I had no room at all and it cost me $120 for luggage. Additionally, I missed my ferry in Paris Athens. I had to rebook my ferry and I could not get a refund so by them canceling the trip for four hours it caused me no ferry to go to Betsy. I had to find a room that night. The only one I could find was at the Hyatt grand in Athens And I lost a night. Stay at Betsy that I had already prepaid so no my experience was awful. Additionally, they never said on any intercom that Greece was one hour ahead of Paris so that was a problem. We had no idea and when it was never communicated to us

Ove Aegean Airlines! Used them for several flights over past 4.months. never flown w them before but will certainly use in the future!!!

A thoroughly enjoyable experience in business class, which we “won” in the airlines lottery In exchange for a relatively small deposit. The breakfast served at the beginning of this three hour flight was absolutely phenomenal. I would be tempted to fly Aegean airlines on a transatlantic flight in light of this experience.

Was grateful that this flight was held for us as we were late from our prior flight.

Our connecting flight from Barcelona to Athens was late and it appeared that we would not make the connectimg flight to Telaviv. The plane ended up waiting and we made the connection. The airline redeemed itself.

Lovely experience with Aegean. The crew felt with some extremely rude customers with professionalism and poise. The flight went off without a hitch and even landed early!

Flight was late and has 12 hours transit time instead of 1.3 hours.

Comment for Lufthansa is just perfect, similar to my first flight comment.

Flights were extremely delayed, then canceled, our baggage was lost due to this and the service reps at the counter couldn’t be bothered to help us put in a missing luggage claim.

It was my first experience in business class. It was everything I expected and more. Service was impeccable, food was delicious and I felt rested once I arrived to London

No Wi-Fi or food unless you pay an expensive fee.

I remember flying with Lufthansa many years ago, and it used to be an amazing airline with more technologically savvy and roomy planes, but unfortunately that isn’t the case anymore. The space between the seats is much smaller, which is ok for short flights, but definitely not for across the Atlantic flights. Not sure if I’ll opt for Lufthansa the next time, maybe just if necessary.

Flight took off late. Flew business class. Lunch choice was chicken or vegetarian gruel. Chicken was gone by the time the flight attendant got to me. Got the salad, rolls, and desert. Skipped the vegetarian gruel. Almost broke a tooth on the roll. Suspect at it was least three days old...bird food. Wheelchair service (for spouse) at ATH was outstanding. Wheelchair service at FRA was mediocre as usual/expected.

My first two flights were late. I missed my last flight. The next flight was not until the next day Seating on large plane was uncomfortable. In the center row, there are posts that do not allow you to spread your legs. The entertainment center did not respond well. . Food was okay. Though there was much confusion about where the special meals that. People ordered(not me) went

Leg room was ok 1 flight attendant threw headphones at us. Very rude Overbooked flight thank goodness I got a seat Bathrooms smelled and urine all over the floor

No assistance as requested. Very late take off. Very hard landing And again , no assistance after landing

Terrible service especially for premium economy. Much more comfortable seats on other providers

Friendly hosts/hostesses; dinner was of acceptable, but mediocre standard

Very caring crew on board. Didn’t have dinner as I was sleeping. Was seating in the emergency row so I had comfortable leg room

Had a nice little suite although I couldn’t close the door (but I didn’t ask anyone to help). 5K is a nice seat and very private (you look in on first class). Enjoyable flight and nice crew.

Crew was excellent. And no surprise that the seats aren’t comfortable at all. But that is every airline.

Although the crew were great and the good nice, I might as well have been on Ryanair for the amount of space I had. Not good enough BA. I’d rather pay more and not feel like a human sardine.

Love the A380 - loads of room. Headphone socket on my seat didn’t work. Sounds like a trivial issue? Well when flying long-haul the in-flight entertainment is what keeps you going so when it doesn’t work it’s a disaster. Pay attention to the details please BA. Spoiled what was otherwise an excellent flight with the usual brilliant crew.

Crew were fantastic can’t fault them at all. Couldn’t do enough for us

Crying baby the ENTIRE flight. Not your fault, but I paid 2700 for a premium economy ticket and it wasn't worth it. should have just stuck with coach. flight attendants very mediocre - minimal effort. Plane didn't seem very clean. Didn't have any cleansing wipes - most airlines give you this when you board. Flat screen scrolling didn't work. Toiletry case a joke - why bother at all?

I was told to be there to check in three hours before my flight and the counter only opened up two hours before. Apparently that is standard. So that was an hour I could have spent walking around Larnaca that was wasted. But besides that it was great
