Checking in took very long for whatever reason. Flight comfort these days is always poor so… Crew was great thought!

Checking in took very long for whatever reason. Flight comfort these days is always poor so… Crew was great thought!

Bags lost no more to say, bad communication and no urgency to get it back to the hotel by the airline properly the worst airline I have used.

The customer service rep on chat refused carrying golf set at no charge that is customary for LOT and others. I wanted yo carry just ONE club not even full set! Web check in was nightmare. Most horrible lounge at warsaw. To call it business class is a BIG exaggeration. Rude staff warsaw to nyc. Seats uncomfortable and not flat as is now customary. Bad content and entertainment system.

It was was okay but the seat was stiff and hard to sit on it!!

Seats were so uncomfortable, my butt hurts so much, I wish they have more cushions,it really was horrible, Except that, Stewarts were polite food was decent

Plane is super outdated, seats not that comfortable for business class. Lounge also out dated. They need to catch up to 2024. Don’t think I’d ever fly again.

Everything was good, flight was smooth and on time Like service

Boarding was impossible to navigate. Had mobility issues and a business class ticket, but still boarded almost at the end of the queue because there was absolutely no organization or assistance.

Aircraft was new. Food so so, especially vegetarian was very disappointing.

LOT told me on my first flight that I had missed boarding my second flight and told us to go to a service desk to reschedule. We then were told our flight was still boarding and that we had to run through the Warsaw airport to catch it which is just a long long runway airport. The workers at the airport were not helpful at all and you have to go through two passport checkpoints. I have asthma and was almost dead when I got on the plane and no one helped or gave us water or even acknowledged us. The flight was fine - the crew members are not friendly so it’s a very functional flight at best. Also my bag didn’t make it to my final destination.

Five star experience all around except for my seat, which was broken. It would only go down 70%.Of the way. It defeats the purpose of buying a business class ticket if you don’t actually get to lay flat..

I love this airline.God bless CAO and the whole staff of this company

Great staff, efficient and knowledgeable. Very helpful with others and considerate towards those with children

WiFi would have been nice and some more powerful usb ports, available ports could not keep my phone’s charge much less charge the phone.

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.

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.

Friendly staff, always good food , as comfortable as it can be in economy

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

It was fine, definitely older planes with no charging or anything. There’s no entertainment set up on board, but it is nice that they allow you to access the in flight entertainment from your phone without having to pay for the Wi-Fi and they do offer free texting.

I liked that the flight was nonstop from ORD to CIU for $200 round trip.

The schedule to Moline changed 5 times. The gate changed 6 times. That is a pathetic way to run an airline. No wonder that no one in our company flies on United Express to or from Moline. Changes happen most of the time. I learned my lesson on this trip…never again!

All flight attendants could benefit by taking an international flight on Qantas Airline. Qantas attendants are much more hospitable in every way. Much superior than and attendants on any US airline.

While the staff was pleasant and helpful, the following observations are for your awareness. There was some delay on the tarmac on take off and landing. The paid lunch/food offerings were limited. Entertainment was only available on WiFi at a cost.

The first flight was better in terms of the aircraft.

So far so good but food and entertainment are not available for this flight

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.

Overall poor for me I paid extra for seats with leg room and my regional flights exit row seats have less leg room then the others that's money that could have been saved and on my final flight home the flights air was not operating it was unbearably hot in the cabin I will be contacting United and filing a DOT complaint

It was my first time with United Airlines and I would say it was very good experience and best of all the flights were on time. Will definitely fly with United Airlines next time.

Everything was very good, except that the plane was an hour and a half late

I liked everything: the work of the flight attendants, the work of the crew, the frequency on the plane and in the toilet.

The check in process at Istanbul airport caused my family a great deal of stress and disappointment due to the following factors: 1) WE HAD TO PAY US$330 for check on bags, despite holding Economy tickets that Turkish airlines website clearly states that flights from Istanbul to Miami had a 2 checked bags allowance. 2) Airport staff not only lacked empathy for senior travelers (75 yrs old and 71 yrs old), but were also rude as well. The supervisor at check it offered "if you don't pay for the bags, you can just remain and sleep at the airport for however long you wish. What a terrible way to treat customers !!! 3) We were bumped from agent to agent to agent FIVE times, showing everyone the communication we received telling us we had the 2 bags entitlement. Two elderly people lugging 4 suitcase around and around the Turkish terminal. Again, what a sad way to treat customers !!! 4) We need a case opened to get a refund for the amount we paid. Something is amiss, screams unethical, and sounds unscrupulous......At First , we were told we must pay for 4 bags. All of a sudden, it became 2 bags, and finally all 4 bags were checked on with payments demanded for 2. Why did it vary from agent to agent???? 5) OVERALL, A TERRIBLE AND SUSPICIOUSLLY UNSCRUPULOUS EXPERIENCE FLYING WITH TURKISH AIRLINES. WE ARE TERRIBLY DISAPPOINTED AND SAD THAT OUR VISIT TO A BEAUTIFUL CITY ENDED IN SUCH A HORRIBLE EXPERIENCE

I recently flew with Turkish Airlines, and I can confidently say it was one of the best travel experiences I’ve ever had. From the moment I boarded, the crew was incredibly attentive, warm, and professional. They went above and beyond to ensure everyone was comfortable and well taken care of throughout the flight. The highlight, however, was the food! I’ve flown with many airlines, but Turkish Airlines sets the bar incredibly high when it comes to in-flight dining. Every meal was fresh, flavorful, and beautifully presented. The variety of dishes, even on a long-haul flight, was impressive. It felt like dining at a high-end restaurant at 35,000 feet! The seats were comfortable, the entertainment options were great, and the overall atmosphere made the journey enjoyable. Turkish Airlines truly excels in combining luxury and hospitality. I wouldn’t hesitate to fly with them again—highly recommend!

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

In this long haul flight, flight attendants never stopped moving and giving excellent service. Very impressive. Very comfortable seats and excellent food

In sharp contrast to the modern glitzy airport, boarding facilities were primitive. Passengers had to board buses and walk up steep stairs in bitter cold with carry-on baggages. I found no reason why aerobridge was not provided.

Service and food were decent, seats are a bit too narrow. Leg room is normal. Bathroom should be cleaned more frequently. WiFi is cumbersome and should be simplified.

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.

The boarding system was all bogus - employees at the boarding gate were not sound like proffesional or may be possibly rational

I got an email in the morning of the flight 1/7, from Kayak, that I was rebooked from UA 906 to LH 430. Nobody at Lufthansa ot United knew about this. I went to both counters. at the airport. Also, Cheap Flights, who I booked the ticket through, did not know. I ended up staying on the United flight. But this was very disturbing, since I got a very late notice that I was rebooked to an earlier flight, I hurried to the airport to find out after a lot of inquiring that this was a mistake. Not a good Kayak experience.

After living in Europe for five years and flying with Lufthansa and KLM airlines, I’ve realized that United Airlines is now a budget carrier. The flight attendant are not friendly. The seats are not comfortable. And everything comes at a cost. I will be flying with KLM and Skyteam like Delta to the US going forward no doubt. United Airlines is not what it once was:

Delayed take off but I think they waited for passengers.

I had to fly United where the flight crew was atrocious
