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.

Excellent flight. The crew was exceptionally attentive and organized. Attention to details is unmatched.

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.

They had me unpack a handbag 2 lbs overweight into another handbag 8 lbs underweight for a Bible.

One thing I really liked about Austrian Airlines was that the flight attendants were very kind, and the in-flight entertainment offered many choices. One thing that could be improved is the meal service, since only a vegetarian option was offered — it would be better to have at least two choices

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.

My seat number was changed unilaterally after confirmed online checkin from widow to aisle. This applies to the Istanbul-Port louis flight. Seat was also changed for the Antalya-Istanbul flight but this was because of aircraft change, I was informed. That flight was delayed because of a technical problem with the original aircraft.

flight was full and folks coming from Dubai all wear this strong perfume (OUD) which is annoying. Also, not sure why but these fools all stand up and get ready to bail once the plane stops. they seem to all run for the door which is funny AF. Plane was a 2 4 2 configuration and kind of an older plane with USB connection. Food wasn't that great either. Not sure i'd take this airline again since i have no plans on going to Istanbul again. Emirates is definitely better if you want to go from US to DXB,

So boarding is a little slow when you fly 787 but on the 777 the business class had its own entrance. The entertainment can be a little bit more up to date Other than that it was a great experience food and service was great

I paid $150 to upgrade to this seat. My exit row seat had ample leg room BUT the collapsable table was broken so my food tray and drinks slid over to my lap, the screen malfunctioned.

it was a terrible experience. after 4 hours at the gate the flight was cancelled. the airline offered to rebook the flight for 26 hours later. Our team was travelling for an international competition. They missed the competition because the airline delayed them for over 30 hours. We already left the airport but the next morning we received an email stating that we were rebooked for a flight which was another 24 hours later after the already rebooked flight. We bought a ticket on Kayak. The reservation was delivered with a logo Airfareassist. I used Kayak services for over 20 years and assumed that I was dealing with a legitimate organization. Once the flight was postponed for over 40 hours, I learned that Airfareassist is a 3rd party agency whom kayak routes business to without notifying me, the customer. While I was entitled for a full refund, which was confirmed by the airline, Airfareassist only offered a partial refund and kept the difference. Kayak has failed to do a due diligence on the 3rd parties they do business with. As a result I will never do business with kayak again and am filing a complaint with the BBB and the Secretary of Transportation. This is a pure fraud and its unacceptable.

Everything was so smooth. It could be just a better temperature in the plane; it was a little cold.

The staff at IST airport could have been more helpful. Too much wasted time and the plane from IST to KHI was just horrible. The plane was not clean and smelled bad!

Boarded via bus instead of the air bridge Had to wait 10mins in the bus at the tarmac before we were allow to go up

Staff friendly. Business class but issue with flat bed. Incoming Turkish flight delayed. Made connection due to fast buggy but luggage did not make it. Confusion at Delhi airport

I loved and appreciated the agent at the check in counter in Amman. He was very professional and helpful. I believe his name was Lawrence. All I saw from him were smiles after smiles after smile. Very kind and professional. Overall trip was comfortable and pleasant.

This flight with a lot empty place , and I have more room, feeling comfortable.

Flight was good, breakfast could be much better. We had come from a domestic flight on the same aircraft and the domestic flight was much better regarding service compared to this international flight.

I accidentally touched a cabin steward as she passed by and she reacted harshly yelling in a loud voice “don’t touch me”. It was embarrassing and uncalled for. I would characterize a few of the cabin crew as pretentious and aloof. Not at all what is expected. That was the first leg of our trip from Montreal to Munich. The second leg from Munich to Nice was more in keeping with the service I expected.

The staff could not have been any friendlier. Lots of usb ports on our aircraft.

It was crazy, boarded over a hour late from scheduled departure. Then when arrived in BNA issued with getting off the plane…over 1/2 hour. Not looking forward to flying Air Canada, ever again.

Great flight. Only complaint is it took over an hour for my luggage to get to the carousel on the return to LAX That was irritating

The service to/from the airport/plane (wheelchair assistance for my mother in law) was exceptional. The staff was super friendly and courteous. The staff on the plane was also very nice. The food quality could have been better (mashed chicken sandwich).

The flight was great. I like it when airline capitalism give you information. For someone with flight jitters it really helps. And this captain was very cheery and reassuring. I had trouble understanding the head flight attendant because she spoke very fast. But overall staff were very helpful and kind.

1 hour late No hot drinks No restroom in the back of the plane

I did the posting for 45 years. I just retired. I’m the only seat in the plane but didn’t have any phone. It has to be mine so imagine seeing 13 hours on the flat seat with a belt that didn’t close all the rest was OK.

The service and food was excellent. The remote control for entertainment did not function properly.

All was good, except my USB charging did not work, so my phone got drained and I could not charge it. Same happened to my neighbour.

A bit more space? Not practical, I know. I felt squished in but part of that could have been the man sitting next to me.

I purposely bought a seat upstairs and your airline moved it to a random aisle seat. The only good part about this being an older plane was that the seats weren’t so tight that I couldn’t relax at all. Still will never fly Lufthansa again.

The plane (Mitsubishi CRJ) felt old, creaking and not very new. The crew was okay. Hot water provision was broken so hot beverages could't be served.

Not bad. We had preboarding tickets but the preboarding was badly managed. We lined up behind all the parents with little kids etc and when we got to the front of the line the attendant deliberately turned away from us and ignored us until I asked to be allowed to go to the gate. She started telling us that we had to wait until I told her we had preboarding then she let us through.

The crew was fantastic. They were always there when we needed them. No wifi on an 11 hour flight was a bummer. The entertainment onboard was boring.

Everything well done and customer oriented There entertainment system is difficult to navigate

They delayed my flight from Toronto Pearson for one hour and Frankfurt to Abuja for 2HRS, So sad

The aircraft was old, there was no charging sockets, and the seats were narrow and uncomfortable even though I had exit row premium seats.

Decrepit planes, poor business class layout designed to maximize revenue, no decent movie selection.

The leg from Portland to Heathrow was great for a business class ticket. The BA leg from Heathrow to Lisbon was terrible. Basically coach seating with an empty seat between you and next passenger. Absolutely no leg room. Should not have been charged for business class and it was a 3 hour flight.

Both flights Heathrow and to SFO were delayed significantly. Walking up outside steps to aircraft with suitcase was a challenge and I am a healthy 63 year old!

They need to improve their service at the airport. Rather than a bus, they need to park the plane at a station like normal airlines to so passengers can just walk out of the plane into the airport and catch their next flight

Horrible experience. They broke the handle of my checked in suitcase and then refused pay for damages

The plane was known to be late in advance of takeoff. My guess is that it was known to be late at 11am or 5 hours before scheduled takeoff time. We were late to leave and with a wheelchair and the a cart, we only made it to gate. We raced! Inside plane, all was great

We spent twice as long on the runway waiting to take off as we did in the air.

I got stuffed on both flights into terrible seats. Second flight the seat didn’t even recline and fit s tall person, that’s very uncomfortable.

Boarding market okay just because of the delay we had, but not related to the crew in any way…

The calls for our boarding group weren't heard/clear.
