Airline reviews
Pros: "I liked almost everything. And according to me, it does not make a difference if we rate things good or excellent at a certain point in time. As long as it is good, it can be excellent. I mean including crew. People have good days and bad days. I am sure the crew can say the same about passengers."
Cons: "What could have been better is: - the email that the airline generates and senda to people a couple of days prior to flight directs you to a site where you are supposed to fill in the blanks. About Covid. The thing is that you cannot submit it unless you as a passenger fill out an Austrian address. The electronic form does not have the option to rule out staying in Austria and indicating that you are transiting in Vienna. I had to fill that form out (at the Address in Austria section) with sentences like “not applicable” “transitting” and also had to google the Vienna Airport address for the zip code so it could be submitted. The form forced me to fool the it. Not cool. Frustrating."

Pros: "Austrian Airlines is the best! Crew, food, drinks, entertainment, and plugins were all provided, and it was all very nice (and delicious food!)."
Cons: "Nothing! Love Austrian Airlines!"
Pros: "The entertainment system was good and the crew excellent. The person in front of me did not put their seat back which made my trip more comfortable. Loading and unloading was orderly and efficient."
Cons: "Food could have been better"
Cons: "lastminute.com was completely unhelpful in assisting with any changes to my itinerary. They repeatedly provided me with incorrect information that sent me on a wild goose chase."
Cons: "Don’t tell passengers they can make a transfer flight supposed to leave in 20 minutes because the first flight was late, and then have the plane leave without the passengers who sprinted through the airport after having to go through customs and security again."
Cons: "40 minutes waiting clearance for boarding and then for departure, for a flight 45 minutes in duration..."
Pros: "Seat was very comfortable and lots of leg room. Food was good."
Cons: "Seat spacing is small, to the point that it's impossible to remain in the seat few hours without physical pain in your body"
Pros: "entrance with classical music! staff was friendly. probably in top 5 flights"
Cons: "nothing"
Pros: "The staff were nice, the flight was on time. The meal was good."
Cons: "There was no pillow on board and the flight was overnight."
Pros: "Crew super!! Entertainment very good"
Cons: "Plane excellent condition and super clean. Take off and landing on time"
Pros: "I enjoying having an aisle seat plus two empty seats next to me. I appreciated that you are conserving plastic cups. Keep up the conservation!"
Cons: "All of our luggage was lost and did not arrive in Prague"
Cons: "Tv screen didn’t work very well. ( picture was fine but the function buttons were terrible)."
Pros: "Very friendly, helpful and communicative crew."
Cons: "Only complaint: the touch screen on the seat back was oddly unresponsive and this made it a bit difficult to interface with the various in-flight entertainment options; the streaming music in particular."
Pros: "The bus was one of the most comfortable international flights I have ever been on."
Cons: "Somehow, our luggage never made it to Rome, despite a nearly four hour layover in Munich. Disappointing."
Pros: "Great crew. I love Lufthansa. I just wish there was more room for my legs."
Cons: "More leg room!"

Cons: "FOOD WAS DISGUSTING !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"
Pros: "Amazing service, the crew the seat was comfortable, the meals exceed my expectations, the movie selection, everything was awesome."
Cons: "Can't think of anything.."
The biggest problem was getting our bags in Montreal. It took 1 hour. The flight itself was good.
The flight was delayed. They assigned us a direct flight instead, We are very happy with the changes!
My flight was delayed, cancelled and delayed again. I lost one complete day in Japan, a very needed vacation. My schedule / itinerary in Japan is now all screwed up. It will take more time and cost to resolve this. So, am I happy with Air Canada; NO!
Ground staff were aggressive in insistence that I must my gate check my carry-on bag which easily fit in their sizer. Others were not being forced to. I was called to the desk pre-flight to inspect my bag. Because I had a cheap ticket? Not sure. They let me off when they learned I had a cpap machine in it. In the end there was plenty of overhead space.
Cons: "I was made to pay for my carry on because of weight. I didn’t understand that when I booked. I am also certain that many other carry ones were more than 12 kilos."
Pros: "Nothing. Crew unfriendly. In AC You should pay for everything, including the seat or you are in risk to no board because the oversell"
Cons: "Everything in all the process. The airplane is the worst"
Cons: "Seats next to bathroom row 30 - not good. Delayed 2 hours before departure"
Pros: "Staff polite and provided fast service."
Cons: "Boarding was hazy and let room for loosing the plane."
Pros: "The flight was running late due to technical difficulties but they did take good care of us. Even the rescheduling of the connecting flight was easy."
Pros: "got an upgrade to Business Class but on those small flight - meh"
Cons: "The recline didn't work nor did the sound on my TV."
