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 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.

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.

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

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

2 hours delay on the plane causing is to miss our connection

Overall great experience, flight was good and crew was focused on safety and comfort

Issue with boarding, group of passengers on a religious trip coming back to NYC kept trying to change seats, even standing when the plane was pushing back. Crew/Pilot kept very good composure, some passengers got aggravated and started venting out loud but this group created a serious security risk. Crew/Pilot should've been more stringent and called in security or remove them from the flight.

I have flown over 2million miles. Great flight but bizarre boarding process. They must have paged half the passengers to the desk for documentation check before boarding anyone. Overall great value.

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.

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

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

Once again very friendly helpful staff A short flight but not only on time actually a bit early

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

Horrible trip. Plane was late , so late . the flight conditions were very uncomfortable.

I was in the premier economy and enjoyed the room and the comfort. Although I will say that it would take a real expert to make the location of the place to plug in headsets and chargers more difficult. With all of the room available it makes no sense to bury those connections and to make it so difficult to use them. The couple in front of me needed to use the cell phone light in order to see where to plug in a charger. The seats are comfortable and the food was good.

Short flight. Bare bones and kinda seeming like an older plane. But got me there on time and that's what counts. Perfectly fine flight all the way from start to finish.

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.

I love this airline.God bless CAO and the whole staff of this company

Great staff, efficient and knowledgeable. Very helpful with others and considerate towards those with children

WiFi would have been nice and some more powerful usb ports, available ports could not keep my phone’s charge much less charge the phone.

We didn’t fly into Neuark , because it departed without us . We ran to a closed gate , and no staff to assist, then to a customer service center that was also closed, then briskly walked (20mins) to another customer center and got a ticket , waited 2 hours , got a flight to JFK instead, because of the time delay we Ran to catch our train home , and again our luggage arrived 3 days later delivery time at 3:45 in the MORNING!!!! Crazy!!!!!! Took a few days to shake off this disappointment of your service. You’re an embarrassment to customer service .

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.

Austrian was not the issue. Kayak was terrible The flight was canceled. Frustrating but it can happen. The worst was Kayak's customer support around re-booking. I have chatted with a bot, than with a person who insisted the flight was still on as originally booked. while chatting i went on Austrian web page and told the kayak chat lady that the flight is shown as cancelled. She said she will escalate this and that someone will contact me within the hour. When I have asked her to give me the details of the flight she sees, She gave me the general A to B and return B to A. Totally unhelpful. After two hours I contacted them again, They were still saying the original flight is as scheduled and when I explained again I was told I will be contacted within 2-6 hours. NO ONE CONTACTED ME EVER SINCE! I have than contacted Austrian directly and was rebooked on a difficult flight. Kayak continued to send me irrelevant updates about my original flight. Terrible customer service at time of need.

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.

As always, Lufthansa checked my carry-on luggage, even though I was in front of the line. No other airline in the world does this. It's so annoying and unnecessary. There was enough space for it in the overhead bin. It's a TUMI Continental Carry-On. If you have the chance, rather fly easyJet or Condor on this route.

Someone sat in my seat and this made boarding protracted and unpleasant. The stewardesses kept saying, “it is important that everyone be seated — or we will be further delayed,” but for a long time they did not tell me where to sit. At the end of the flight a baby screamed loudly for several minutes and it took ninety minutes (!) to get through EU passport and customs. We had to stand the whole time in a an overheated room. The seat on the plane was narrow. These things are not all Lufthansa’s fault but they made for a somewhat unpleasant trip.

Everything about the flight was excellent except for the fact that we had to wait one hour on the tar app and then I had to race to catch my connecting flight with the next stop

The flight on time, flawless check in and boarding process, the crew was very friendly.

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.

My experience on this flight was good. The seat I had had a lot of leg room, but it was so close to the aisle that the flight attendants kept bumping into my visual monitor connected to my seat to watch tv.

It was fine, but it cost me twice as much to return to Boston as it took me to get to Heathrow from Boston two weeks prior. I flew on Jet Blue over and it was half the cost of British Air.

Staff and comfort were great but first choice meal was unavailable even in row 21.

My only issue with my flight to Jersey was that the Gate wasn't announced until shortly before boarding, otherwise all went well even with how busy Heathrow was. I appreciate British Airways staff's politeness, hospitality and positive energy.

Cabin crew was very good. No wifi and no doors to the suites

Very timly. Great service !!! Pick up after meals can be swifter.

Straightforward boarding process. Pilot kept us informed during the flight, especially highlighting the fact that we would experience "significant braking" when we landed on the short runway in Florence. The flight attendants were pleasant. My chief complaint is that I was stuffed into a seat in the rear of the aircraft (row 29?). The seat pitch was soooo tight that my knees were hard against the seat in front of me as soon as I sat down. One inch more room would have made a difference. Thankfully it was not a super long flight, but it was quite uncomfortable and I had to work out the kinks in my knees once I deplaned. Is it really necessary to have the rows this close together??

Would not let me board with my fragile guitar so had to check it in. Who knows what the icicles did to it. Not happy. Had to run to catch my connection in Heathrow. After a bus and a train? Was asked by a guy in the middle seat to change my window seat with his girlfriend's middle seat further up in the plane and I was insulted. What nerve! The food was unhealthy and the seat was cramped. Could not wait to exit.

need more US friendly food options. Directions on getting to the next gate were terrible - resulted in long walks to the terminal and then finding I couldn;t enter there and had long walk back, then train to security then train back to where I started in the first place

We never made this flight due to the flight from Barcelona being delayed, which I have reviewed in a separate review. But I can tell you that the Delta Airlines flight that did get us home, I am extremely happy with them and their crew. The only one person that I would praise within the entire part of BA is the girl I spoke to in the call center in India. Who completely understood, was dedicated to a resolution and was a complete realist in the situation. Unlike some of the people who don’t care about the human element and stick you on a flight whenever. She got us home.
