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.

Not good, the seat was broken and the middle seat table was not lowering, no option on the food, despite the business class wasn’t full. In the menu offered they had fish or chicken, no chicken available when was my turn (seating in raw 2!)

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

Krakow airport is very disorganized. nice seats. friendly crew. long legs had screens. short leg did not

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

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

Smooth flight, excellent crew and good food. Not enough space; sitting are too small.

No WiFi and ok comfort in business class. Home safe I guess that’s all that really matters.

Crew was excellent. Business class was poor on the short flight and mediocre at best on the international flight.

Very poor. Seats like economy class, food unbeatable, no charging, no entertainment, no WiFi, boarding by bus - no justification for calling and pricing this as business class

Boarding was delayed for an unknown reason for more than an hour. While the airplane was at the gate, the boarding time was moved by 10-20 minutes every 15 minutes. No entertainment on the plane.

The flight itself was pleasant and on time. Crew was very good. However, breakfast food was barely acceptable. Unfortunately this satisfies the recent industry standards. I asked for a sandwich with ham (another choice was cheese), but received a sandwich with roast beef.

During the flight, the fleas biting me in the plane.

We were delayed three hours from Montenegro to Vienna on our outbound flight and then rebooked an extra leg on our trip to the US. Our bags, which Austrian made us check in in Montenegro even though the flight was barely half full, didn't find us for ten days. Then, when we asked for compensation for the delay we were given the runaround that the flight originated outside of the EU. Next time we fly Turkish Air.

My Austrian Air flight from Montenegro to Vienna was delayed by three hours because their plane de-icer was broken and they had to wait for the sun to come up before the ice could melt. This meant we missed our United flight altogether. So I can't speak about United, but I was not impressed by Austrian Air. They made us check in two carry on bags for a 60% full flight, and the bags didn't find us in the US for ten days. The re-routing they arranged included an extra leg, a midnight taxi ride across New Jersey and New York, and a five hour sleep in a hotel. Not impressed.

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.

Great! They got my vegetarian meal right, flight was comfortable, they helped store my heavy luggage. Pleasant crew and flight staff.

My layover in Vienna was supposed to be 35 minutes but because my flight was canceled I had to wait in the airport for an additional 8 hours.

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

The flight was delayed for 30 minutes with no apparent reason. There is no entertainment at all, and no USB or electric outlets for charging your phone or tablet.

Despite the booked seats in front of the land we were moved to the back of the plane even first like 8 lines were totally without pasangers. When I tried to sit on empty seat flight attendant asked me to go to my dedicated seat in the fully crowded back of the plane. She was not able to explain why. Food was very poor on flight LAX - VIE.

We had a wonderful experience overall. The only issue was check-in our luggage at the Split Airport counter. It was very confusing because we needed to pay for baggage.

Austrian Airlines help and service was fine, but Kayak misled us into believing we had purchased a Business Class ticket. In fact, the tickets were only upgraded Coach Class tickets with luggage restrictions that belonged to the Coach Class. Very disappointed! Paid over $$$$ 9K for the two tickets. Very disappointing!

I ordered Hindu meal and expecting a vegetarian food. Instead I got Chicken. Also entertainment system was so bad and slow I was never able to use it

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.

I paid extra for more comfort, didn't get any better than any other seat, tv didn't work on both seats, it'd

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!

It was as good as a flight in economy can be.

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

This experience was a complete disaster. At first the flight was delayed. No reason given why the flight was delayed. Once transported to the plane (by bus) and waiting on the tarmac, the flight was canceled. The next flight was 6 hours later and that flight was also delayed. Horrible experience and lack of communication from the airline.

Boarding and flight update was fantastic as I experienced about a 10-15 delayed for both flights. The food served onboard was great; the service of the flight attendants was excellent.

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.

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
