The preboarding and the gate organizing management was poor, unorganized and mismanaged. While standing in the business line I kept getting ignored and the personnel kept checking in others, right in front of me until I finally spoke up and pointed out their clear signs of ignoring me while patiently waiting to be checked in. Once checked in the gate the personnel kept chit-chatting and not managing which group is to board, being totally nonchalant, unorganized and behaving amateur-like . Very unprofessional and unlike the quality the Austrian Airlines brand otherwise provides. The crew on the plane are always fantastic and the best. What a shame the crew on the ground was so mediocre.

What a shame the crew on the ground was so mediocre.

Flight delayed with no explanation. Boarding was confused (proceed to plane, go back to waiting area).

Last few years I didn't not have great experience with United Airlines.

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.

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.

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.

I been flying with Austrian for few years, they never failed me.

Vienna airport is a zoo Agents directed me to the wrong gate and then the wrong line Lounge is so crowded no place to sit Not enough bathrooms anywhere On the flight they asked for medical attention While I attended to the problem they forgot my food when I got back They forgot to give me water at night Waited 1 hour for bags Agents didn’t know which Shute the bags were coming to so it was between 2 places

Food: my selection was pasta with vegetables, though it was potatoes not pasta. Breakfast was 2 rolls and some sort of spreads— not sure what they were. Worst thing was that we had to wait for over 90 minutes for our bags to show up at O’Hare

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.

Amazing crew, delicious food and drink selection. 12hr felt more like a 4hrs. Comfortable beds. Can’t wait for the new business class cabin

Flying business class saves you. Once you get out of the terminal and onto the plane, it’s fine. The traffic at the gate is a horror. No organization at all. The fact that Business class is promised early boarding is a myth.

The seat was paid for but given for some different person .

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

Flight was delayed for a hour from Warsaw, not sure why. When we landed in Chicago, plane was still on the runway for about half a hour. Took a while to get off.

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

I would like to be able to choose the seat before the flight without paying extra money. Family members should not to be separated from each other.

Flight was delayed by a hour could have been better addressed. Flight was fine with great service by the flight attendants

All good. Didn’t get the seats I booked online. Luckily, copassanger cooperated! Mistake- I failed to verify connecting flight seats details at Mumbai. Staff at Mumbai airport to be blamed equally!

Horrible service at the baggage claim. Stuck on plane for an hour due to taxing and no gate.

I really would like it if they provided at least some limited free wi-fi.

Excellent food and service on my international flight. Most notable is the food provided by Turkish even for coach passengers is very good.

Food is very turkish. No regard for other natinalities taste and preference. The entertainment can be improved- it was the same menu on 10/8/25 and 10/25/25. The boarding is the worst in the airline industry- I suggest you ask your staff to and watch how other airlines do it.

We couldn’t fly to Chicago on our booked flight. The flight was overbooked.

Took forever to board. They made announcements without the loudspeaker and since the waiting room was full of screaming kids, no one could hear what they were saying. The business class sleeper seats were designed for tall skinny people. When partially reclined there was nowhere to rest my feet because they did not reach the footrest. and when fully reclined there wasn't room at my sides for my arms. Definitely one of the worst sleeper seats I have ever had.

About an hour delay but we made it to Chicago. I feel that the smaller connecting flights are the ones that cause the delays on the bigger planes that fly international.

One of the best flights I have been on in a while.

Here's a sample answer: "Honestly, I was really impressed with Turkish Airlines, but if I had to suggest one area for improvement, it would be: - *More efficient boarding process*: I noticed that boarding took a bit longer than expected, which might be frustrating for passengers with tight connections.

Not worth pay business class and get service economy class

The flight was delayed an hour and a half while you tried to fix the plane so I missed my connecting flight in Chicago. In Chicago, it took an hour to get the luggage. Then the conveyor belt was broken where I have to transfer my flight from an international flight to the continuing flight so I had to carry a large suitcase through the airport. The elevators were broken in the airport. I paid people to carry the luggage for me up the escalators in two different areas. The person who helped me get the new flight was outstanding. The temperature in the airport in Chicago was horrible. We were all sweating. It was the day from hell. That was after two hours in a security line in Athens. I have TSA pre-checked and global entry and I still waited. Two hours in a security line. Something has got to be done to stream line this service. After I’ve been through all of that in Athens, why do I have to go through it again in Chicago. It was the worst travel experience I have had in a long time. Your bathrooms have gotten so small that you can hardly get your butt on the toilet. You’ve taken the airspace out of the inside of the top of the toilet. It really makes for a miserable experience. Also on a 4 1/2 hour flight from Chicago to Los Angeles. The only thing we’re given is a bag of pretzels. REALLY!!

1 flight cancelled Had to fly out of different city Flight at new departure city was delayed 3 hours causing us to miss connecting flights. By the time we did make it to Prague our luggage did not. Had to wait day and a half for luggage to be delivered. Customer service was not good. Agents did not arrive at gate until 5-10 minutes before boarding

Awful. Delayed flights, missed connection to Toronto. Hotel vouchers were for already booked hotels x3. Giant waste of my time

Boarding was great, and the crew were very friendly. The seats must have been a bit on the older side and you could feel some of the seat components through the padding. Also, the plugs did not work on the row's entertainment screen or charging ports. Checked bag was transferred for connecting flight, and we appreciated how early we had the connecting gate information.

Very easy ! Use the kiosk and bag drop and right to security within 10 min

Prefer not to have an almost 3 hour delay with useless communication that wasn't accurate.

Over 5 hour delay with minimal updates or ability to standby for alternative flights. During boarding and 1 hr+ wait for takeoff, seats were drenched w water from air conditioning condensation and always leftover crumbs on carpet and seats

I flew from Barcelona to Chicago on UA yesterday. The flight was on time, the pilots did a great job and the flight attendants were super nice. All of them. Also food was good, and the drinks, including wine were served a few times during our flight. I highly recommend this airline.

Boarded early, left early, arrived 40 mins early! A win win for me!

These airplanes should be illegal. The seats are two tight, it is a safety issue. Wheelchair support was ridiculously slow. We almost missed our flight.

The legroom was lacking and the entertainment system lacked adequate selection of older films. Modern films are generally not very good.

Perfect airline, super friendly, great service, tasty food. Would fly again.

Everything could have been better. What needed to be wrong with United went wrong

It was good. The seats in economy weren’t bad

Very good. Comfortable and I felt well taken care of from start to finish

We were in premium economy seats that appeared to be locked in plae, No reclining. My aching back.

I don’t understand how they charge as much as they do for such a poor experience

I wish the plane had pod seating for business class. I had a window seat (8K) and I had to climb over the person sitting on the aisle when I needed to get up. Also there is no partition between the seats for privacy when sleeping. The Asian airlines have much nicer business class seating. Their seats are wider for better comfort when sleeping.

The seat space seemed small especially when the person ahead reclined but other than that, very good.

Luggage transfer in Chicago was not performed in time. I received my luggage at my destination two days later.
