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Aegan Airlines compensates for its outdated business-class seats with excellent food and onboard crew service.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

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.

Agean Airlines are the best!!! Kind and pretty personnel willing to help you any time! Kind with the kids and smiley faces! And the only airlines to serve food and drink for free! Yes! This is GREEK HOSPITALITY!! Great job!!

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

Θα πρέπει να υπάρχει εστίαση στη γρήγορη και εύκολη επιβίβαση/αποβίβαση

Excellent service from LOT!!! The entire experience was smooth and comfortable. The staff were friendly, professional, and very helpful throughout the journey. Everything was well organized, and the service was excellent from start to finish. I would definitely fly with LOT again and highly recommend it!

Amazing crew, delicious food and drink selection. 12hr felt more like a 4hrs. Comfortable beds. Can’t wait for the new business class cabin

Every time I fly LOT, I swear I will never do it again. And changing planes in Warsaw is a horror. Not even remotely organized. I can only feel sorry for the staff who have to put up with it.

Boarding was a madhouse. Airport staff was completely disinterested in communicating about the delays. Never again.

The seats are very narrow. Communication regarding bids for better seating could be better

Although I was flying in business class, the feeling, comfort and in general the whole experience was like flying in a low cost airline. Boarding by. Us, no priority to business class passengers. The plane was very old and looked poor and rely old. Seats do not recline. Space between rows very small. No separation between business class and economy. No separate toilet for business class passengers. Of course no entertainment, no WiFi and no charging. Very bad experience

Flight was delayed for a hour from Warsaw, not sure why. When we landed in Chicago, plane was still on the runway for about half a hour. Took a while to get off.

Very courteous staff. Abnoxious passenger in front of me who reclined her seat all the way without warning and without considering the person behind her. My flight ORD-WAW was so much more pleasant because of the courtesy of the passenger in front of me.

I would like to be able to choose the seat before the flight without paying extra money. Family members should not to be separated from each other.

The flight was very bad, the food and the staff was very rude. My last time with them

Booked economy. Seat felt like it was a bit more roomy than my last trans Atlantic flights. I had a nice person sitting next to me. Everything was as good as it could be considering you are 35,000 feet up in the air and in a metal container. Beers, wine, food were all readily available. Plenty of movies and shows to watch. Friendly flight staff

Most of the crew members were rude, flight arrived late and we missed our connecting flight, they damaged my friends suitcase so badly that two wheels had been destroyed.

Very limited legroom in a 10 hour flight.very old plane.

Accessibility serious problems in Viena airport making it seriousely difficult in in-between gates and boarding travel. Pretens of breakfast and service care in the economy pathetic.

We have travelled on 13 December with Austrian Airlines from Yangon through Bangkok and Vienna to Varna. The first flight operated by Thai Airlines was nice and comfortable. I wouldn’t say the same thing about the next two flights which were operated directly by the Austrian Airlines. During our flight from Bangkok to Vienna:  > The service was very poor – serving of food and drinks was disorganized, late and not combined, the stewards were walking back and forth without doing anything substantial for the passengers. Even the morning breakfast was very late with a cup of coffee almost while landing (after a reminding).  > The food itself was OK-ish but for a 12-hour flight, there were no snacks/bites in between dinner and breakfast as it is with the other airlines.  > The cutlery was wooden, most probably recycling, but very unpleasant to eat with.  > The stewards were not rude but not friendly and/or helpful  > And also, half of the passengers had travel sets, others did not. The flight from Vienna to Varna was another surprise: firstly, the flight was late and secondly, they were serving only water free, even the coffee was paid, so were the snacks, but we had to pay to reserve seats. The whole experience is as if it was a low-cost airline. All in all, I wouldn’t recommend using the services of Austrian Airlines: the ticket prizes are quite the same as of the other carriers flying to this destination and you would have much pleasant time.

They lost our luggage and there has been no news for 5 days. I called their office and they said they can’t help us, we don’t do anything about it.

No delays, helpful staff, well organised. The check in and boarding procedures ran smoothly. The only thing that put me off is that the meal had spicy peppers in. I would have appreciated at least a warning (if i couldn't have a choice) so as to simply not eat them because they were too spicy.

From all the segments I flew it was the only one I did not get the option to choose ni seat, I did not get the quality of seat I had paid for. Crew was nice, airplane was clean, but no food, only water and a small courtesy chocolate. Everything else you had to pay for.

Very efficient and profesional .One of the best. I had 20 minutes between 2 flights and still made it amazing.

Original Flight was cancelled Then Baggage was lost on rebooked flight

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 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.

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.

Flight never showed up and there was no one at the airport to help .

We had something like 4 or 5 gate changes, plus a 30 minute delay. The cabin crew as somewhat more brusque than usual. Basically no food on the plane, but that's OK for a flight of this duration.

Not good because in this cancelled and then rebooked flight BA put me and my husband in both middle seats when we were originally seated together in original flight and i was in aisle. I hate sitting in the middle. BA food needs to be better. It was just ok. Thanks though to screw and everyone one for safe flight

Crew members were thorough in checking seatbelts and whatnot which makes me feel cared for because passenger safety is a main concern.

I was sent an email that said my card payment was not verified. When I spoke to an agent , he said my card was not verified and the flight I thought I had to booked was no longer available so I booked another flight on another airline(United). Later I got flight updates , etc., concerning my supposed first flight. So if I was charged for this flight on British Airways/American airlines, I need a refund.

The crew made it a great flight. They were friendly and attentive. They made me want to fly British Airways again.

BA has not been handling priority luggage with any special priority. This time our luggage was distinctly very slow to arrive, well after the first half of items to arrive. Business class flights cost a lot and it would be nice to have that reflected in the speed of baggage handling! (I note that this has worsened in our long experience of BA.) On a different note, we spent 2.5 hours on the plane after landing because of an airport mishap at Boston Logan. The pilot provided reasonably frequent update but more could have been done to ensure passenger comfort, such as more beverage and maybe snack services.

I purchased premier economy seats but I was seated one row off and was sitting in economy my bottle of water and cookie did not compare to the menus handed OP it in premier.

I understand and don't want food on a short trip, but tea and coffe (at least 1 cup) should be free. Nevertheless there was water available and the crew was nice.

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.
