Not so good. I paid for a preference economic seat, and I couldn’t incline it back because it was blocked. They explained me that because is the last before emergency exit. The company new that but it was not explained in the seat selection

It was on time. Snacks could have been provided for free.

Tirana was crazy check in and getting bussed to another gate. Both Germany stops were intensive customs but organized, but that wasn't the airlines problem. The crews were fabulous on the planes. The announcements were not easy to understand in English, slurred speech. Customs inthe US were fast. We waited for luggage, three later arriving planes had their luggage and left before us

Business class old style from 10 years ago. Ok for short flights but nor for 12 hours journey. The passenger near the window have to jump over the passenger seat aisle side or wake him up to upright the seat. That’s not the business class that you expect on long night flight. Seats are not so confortable. And believe it or not no wifi!

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.

Business class is not worth it. Not comfortable and old plane with no privacy or enough space unless you on the single seats

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 .

A bellow average experience. A delayed flight , no staff to assist , running and panic to connecting flight , 2 hour wait for customer service. No luggage when we arrived , luggage delivered 3 days after at 3:45 AM !!!! Much stress and anxiety from this experience. Please repair your Brand .

My luggage was lost and I did not receive any compensation

Pleasant up to Vienna. Afterward (Vienna- Zagreb) was an horrific experience

Everything is good except the dinner and breakfast. The sandwich is very delicious. Toilet is clean, I only use one of them. Flight attendants are very nice. 👍👍

A bit rush for transit. Food and entertainment are not available

Boarding was a little difficult. The gate area at O'Hare was very small and crowded due to multiple gates in the area. Could not hear the intercom, so had to rely on signage to see when my group was boarding and the signage was blocked by passengers standing in the gate. Flight was great and we arrived in Montreal on time.

Multiple delays and not straight answer from the United team

For economy, it was very good. Staff was great, they even let some of us change seats for more leg room... Put an empty seat between us which was fantastic for a 12hr flight. Onboard entertainment was excellent, I think over 200 choices of movies/tv/etc The bad was the barely/nonfunctional wifi that cost either $16.99 or 1700 miles (full flight). It was atrocious... Definitely the worst of the last 3 long haul major airlines I was on the last few months.

Stewardess spilled orange juice on my clothes/seat no help no apology just threw napkins at me to clean the mess up. Not Happy.

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

Electric plugs didn't work. Entertainment system wasn't working

All was good except for the seats, not very comfy.

2.5 hour delay sitting in the plane on the tarmac, you tell me how the experience was

I hope these comments will find their way to AC customer experience team. Me and my spouse 50 years of aged coming back from 7 days perfect vacation... While boarding in FLL flight AC1621, one of the boarding agents (tall aged african american) man literelly yeld at my wife during the picture talking process. MAM ! STEP !! BACK !!! We are not illegal immegrants beying deported, nor are we in the millitary. We are customers returning home. This was unacceptable. While boarding in YYZ flight AC1154, one of the boarding agents (tall aged caucasian) man criticied with several complesant remarks my passport condition saying that I could not travel intl with it due to stain, decoloration, and BLOOD. My passport does not have blood on it! Yes it might be in less than perfect condition, but their are ways to talk to customer that does not imply not allow a boarding agent to be angry fathery like, or a custom agent looking at a suspicious individual. Both experience were less than acceptable for might I remind you a paying CUSTOMER returning home.

Short flight so no food or entertainment. Good landing at SFO and on time. We were told no carryon luggage yet lots of people were puting bags in overhead compartments. The rules need to be made more clear. I was on the first leg of an international flight and this is the first time I could not have carryon luggage.

This flight didn't happen for me because of overbooking.

My flight was overbooked and they would not let me board. I had to book another flight and pay the full amount of that flight. I did not get any help at all from Air Canada or United Airlines.

Comfortable seats and movies entertainment available. Better experience than the flight from Toronto to Denver.

Poor air traffic controller staffing led to a 50%reduction on flights so we got to wait 4 hrs for our flight! Very disorganized at the gate Poor communication with customers

It was delayed by almost 90 minutes and that messed up our plans but it was beyond UA’s control that is what we heard

Terrible experience, flight was delayed both ways. Limited compensation for the 5+ hour delay. Will not be flying Air Canada Rouge, and don’t recommend you do either.

The row of seats were so cramped it was difficult to get in and out of your seat. I even upgraded. A long flight and sad accommodations 😵‍💫 the shorter flight was very comfortable and the seating was spacious

I bought a ticket and paid for for our luggage but I had to pay for my luggage again. I’m so disappointed! We had a 30 min delay and because of that we missed our connecting flight and were told that we would be on the next flight (9am flight ) but we were landed we were booked at 12pm flight. I had a little baby w me, it was very stressful. I begged to leave at 10 am at least. I was emailed that we get a voucher but they didn’t work when we were at a breakfast store. I’ve been always happy w Lufthansa but this time was awful.

Good service … bus transfer upon arrival from plane to terminal: atrocious!!!

helpful and friendly. The Lufthanza people I dealt with before my holiday were so unhelpful by comparison.

We had a 1 1/2 hour delay before we left Denver. When we arrive to Frankfort, they didn’t announce that people with connecting flights to exit the plane first. My next flight was already boarding when we we taxiing in to the gate. I waited another 10 minutes to get off the plane. I had to run to catch my next flight. I mean run! I made it with one minute to spare, but my luggage did not. My luggage came two hours later on a different flight.

My flight was late from US to Frankfurt so I missed my connecting flight flight and I had to wait for long to catch the next flight which was very tiring. Otherwise everyone was very nice.

It would have been nice if my luggage had made it onto my connecting flight as well. Now I have to wait for my luggage to be delivered and that might take a while, which certainly put a damper on the entire experience.

Crew was not happy. Very uncomfortable seats. When person leans back in front of you the screen is too close to me. Food was awful.

They lost my luggage and despite all follow ups through emails and phone calls they don’t give me an update

Everything went really well. Snacks could be better and there was no tea/coffee service after dinner. Crew was helpful and friendly.
