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

Loved the courtesy and punctuality. Very professional and most importantly on time.

Great! They got my vegetarian meal right, flight was comfortable, they helped store my heavy luggage. Pleasant crew and flight staff.

I did wish they would give us the entire little bottle Bailey's instead of just have 1/2 bottle at a time

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.

My flight was canceled and even though I paid אם KAYAK you didn't even answer me and obviously didn't refund my money. I will never buy a ticket through you again.

Accessibility serious problems in Viena airport making it seriousely difficult in in-between gates and boarding travel. Pretens of breakfast and service care in the economy pathetic.

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

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.

Crew was excellent. Business class was poor on the short flight and mediocre at best on the international flight.

Very poor. Seats like economy class, food unbeatable, no charging, no entertainment, no WiFi, boarding by bus - no justification for calling and pricing this as business class

Boarding was delayed for an unknown reason for more than an hour. While the airplane was at the gate, the boarding time was moved by 10-20 minutes every 15 minutes. No entertainment on the plane.

The flight itself was pleasant and on time. Crew was very good. However, breakfast food was barely acceptable. Unfortunately this satisfies the recent industry standards. I asked for a sandwich with ham (another choice was cheese), but received a sandwich with roast beef.

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

Delay rushed to the next plane and bags didn’t arrive in chicago

Agents helping disable person doesnt know connections to Poland and after 9 agents helping and 2hours ,we made it to proper terminal. Polish Dreamliner its Polish nightmare liner with so narrow seats and no room under front seat for bag and feet,in economy class.To upgrade, to higher standart cost an arm and leg ,even there are empty seats No good experience overall

The crew and flight were amazing . However , my bag’s locker got broken and no refund provided . Everything else was amazing except this bad incident that ruined my experience

This flight leg was fantastic - super comfortable and a great selection of things to watch on the TV. Staff were excellent, really above and beyond.

Flight was delayed only slightly before takeoff due to traffic control. However, the flight arrived early to ORD. Good flight. United has been very reliable for me.

Another delayed flight. When the delays exceed the duration of the flight, it’s a problem.

After boarding the plane in Chicago, the passengers were told that there was a technical problem with the plane. Passengers remained on the plane as they tried to fix the problem. After what was probably an hour passengers were told that there was a need to change planes as the problem was not solved. Passengers disembarked and boarded another plane. After taxing to the runway and waiting for takeoff, passengers were told that owing to the thunderstorm the flight was unable to take off but would try and reroute. After some time passengers were told there wasn't enough fuel for the new route and the plane had to return to the gate for additional fuel. after another log delay the flight got underway. On the plane there was food, drinks, ice or entertainment. We were a glass of water, which appeared rationed. Flight arrived about 5 hours late. The pilot was fantastic and communicated with the passengers throughout the ordeal.

Excellent all round, first time flying United. App is very helpful.

Efficient all round, very good crew. Short flight so the food, of course, was just snacks

Better WiFi. I cannot understand that in 2025, United is so behind on a technology that is now a necessity and still painfully unreliable, slow and keeps disconnecting.

Trip was great. A wild landing in Ottawa with the wind and rain, but the pilot did a great job. Always love flying United.👍

Excellent experience. Starting with the agent at the Premier bag drop who noticed I was very early for my scheduled flight and offered to rebook me on an earlier flight with my seat preference. She would not let me leave the counter until she knew that all of the changes and new boarding pass showed up on my United app. At the gate, the flight boarded quickly such that we departed early and the flight was smooth. We arrived 20 minutes early at ORD and I was able to be home in time for dinner. One of the best flights I've had.

Salina to travers city was great! But the sept 24 Tranverse city was not! Traverse city to chichago was cancelled, i went to Denver & got to Salina 6 hours later!

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

They can my date of travel and let me standard in Istanbul for three days stop over and only pay for one day in a hotel with only one breakfast for three days.

the flight was cancelled and I was rebooked twice, once 26 hours later, then another 24 hours later. In total the flight was delayed for 40 hours. Never again will I use kayak or Turkish Airlines for my travel.

Worst experience with boarding once we left the wheel chair even traveling business we had to wait with all the crowd for the bus to take us to the plane then climb the stairs with our bags When you pay extra for comfort and convenience and you don’t get any is disappointing

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.

The best airline for international travel in terms of value you get in business class (service/cost)

I liked the overall flight experience. However, Turkish officials could do a better job at guiding non-Turkish speakers to their connecting flight gates in such a huge & vast airport.

Very small and cramped aisles and seats. Food was poor but the fresh hot roll and hummus was good. No cans of soda given but they had small bottles of water. Crew was nice and pleasant and kept bathroom clean.

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

Small seat space for 13 hours flight, they charged for baggage , very bad quality of food,

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.

Food was poor quality and the screens for entertainment didn’t work properly

It was a short flight, everything was good with it.

I darted through the Frankfurt airport to make my connecting flight. I asked if it was a possibility to upgrade and the agent did. This was the kindest gesture and it made up for the previous delayed flight and distress/anxiety of anticipating that Zi was going to miss my Frankfurt-Chicago connection. I cannot express my gratitude for the upgrade.. I am 5feet 10 inches do the leg space was amazing.

I meant this flight was not good, the one from Tirana to Frankfurt was better!

I was very grateful for Lufthansa's role in organizing mobility support. The touchscreen on my seat was faulty: slow, stained (I couldn't get it clean), and glitchy. This made selecting movies extremely time consuming, and twice I had to start all over from the beginning.

The crew was the best I’ve ever encountered. Business class was spacious, immaculate, and very modern.

I wish seats were not reclinable. It's so claustrophobic when the person in front of you spends most of a nine hour flight leaned all the way back. The crew was really nice though and the dinner (red Thai curry) was pretty compelling.

Our flights were severely delayed, then canceled and we had to fly out next day with no sleep accommodation help. This led to our baggage being lost and the service reps after baggage couldn’t be bothered to help. They kept sending us to different counters when we were at the right counter to begin with. The only saving grace was the angel woman supervisor with blond hair who helped us put in a missing baggage claim.
