I wanted to give them a five‑star rating across the board, but they lost my luggage, and that really affected the experience.

I wanted to give them a five‑star rating across the board, but they lost my luggage, and that really affected the experience.

The flight itself was fine, food was expired and gross, staff were mostly amazing! KLM messed up rebooking for our first two flights that got cancelled and we almost didn’t make it to Amsterdam for an additional two days

I think I previously submitted my feedback about flight lead Katherine in a different field by mistake. Please see those comments. Comments for Hyd to AMS are it was good. The flight lead and service met expectations for satisfactory high quality service but the flight lead did not stand out as exceptional as did the leads on the other two flights so I don’t remember anything specific one way or the other besides the fact I was satisfied.

Flight lead was a gentleman with silver hair and he went out of his way to shake hands and interact with each passenger seated in business class. A medical emergency took place during our flight and he handled it with perfect poise and professionalism. He was gracious and confidently competent. Just what you want from a leader,

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

Seats were nice and comfy. Crew was polite and attentive. Business class is awesome and worth the money.

It was operated by Delta. Boarding took a long time. How difficult can it be? Overall decent trip. Liked the Salt Lake City airport. Better option than Chicago for transfers.

I need it a wheelchair which was provided right away was a great experience whit Austrian Airlines .

Hospitality and service of the staff were excellent. Food was good. The seat was not as comfortable as the other Airlines that I have experience with.

I was in the premier economy and enjoyed the room and the comfort. Although I will say that it would take a real expert to make the location of the place to plug in headsets and chargers more difficult. With all of the room available it makes no sense to bury those connections and to make it so difficult to use them. The couple in front of me needed to use the cell phone light in order to see where to plug in a charger. The seats are comfortable and the food was good.

No way to add a bag without getting in line at the counter, which took at least half an hour. No WiFi.

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.

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.

Excellent hard product, excellent staffs. Lousy app and website that can’t be trusted. App says I have to change my flight due to operational issues. Message was cryptic and misinformation. Have to contact my own travel agent to make sure flight wasn’t cancelled despite Turkish Airlines app and website both denied checking in. Went to airport and had no issues checking in and boarding passes issued.Frustrating and anxiety ridden 24 hours before flight time.

The crew was amazing and the food was really good too

Excellent service. Friendly and attentive flight attendants, can lay back in business class and be pretty comfortable, and delicious food. Flight on time departing and arriving.

I will say the same as my previous comment. Great job over all! From 1-10, ten be the best… I will give 9!

Very hot cabin made long flight uncomfortable, even in business class! Food was great. Istanbul business lounge had great food but too few bathrooms and seating . They also need more electric outlets for charging devices. Appreciate the ability to go through fast track lines w business class

The seats were extremely small. Boarding was not communicated correctly. It wasn’t a pleasant trip.

Loved the food. No wheelchair was provided in Sofia even though wheelchair assistance was confirmed by Turkish Airlines

Boarding experience was a mess- both to and from Istanbul airport. No one knew anything. They asked everyone to line up according to their sit numbers- it was unbelievable. Business class had a separate line, but it was hard to find- I had to go through all that mess before finding it. Would not recommend

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

It was a good experience. With the long layover they provided the TourIstanbul option to have the free sightseeing bus tour - that was a great option to pass the time. Airport at Istanbul is very comfortable and convenient. Flight was comfortable.

Check in went smoothly. Flight attendant who was assigned my area barely paid any attention to me! She acted as though she was extremely busy and flustered. Maybe she was new?! I told her to change the language on my screen, she said she’d come back to help me but never did so I was able to solve the problem on my own. She came back and said she’d made adjustments on her end. Highly doubt it because I found the setting to change the language! Also, I noticed everyone was eating before we landed so I pushed my help button and she never came so I got up to find her to ask her if I can have breakfast. She said they are not serving breakfast but I can have a sandwich. Yes, that was her response as I saw everyone eating breakfast!!!

Please stop those idiotic and unrelenting announcements, commercials and stupid credit card drivel. All together about 15 minutes of stupidness that annoys each passenger.

I missed my flight and had to buy new tickets Rome- Boston

My service dog and I were asked to deplane just before they closed the door - clearly very last minute they couldn’t find the documentation that I have filled out many many times before that is for flying service animals. I purposely purchase 3seats (a whole row) since he is large and not all passengers want to sit next to a dog on a cross country flight. The plane departed with my husband on it!!! They made me fill out a hard copy of the same form and had to reschedule me on a later flight where they could find 3 seats together!! I’ve done this so many times before - clearly the error was on their part in a technology glitch - but really people - do better!! Very traumatic - and my husband had to wait for us when he landed ….so bad. Poor pup was confused and tired.

Super friendly with lots of drink options an entertainment. Friendly crew.

Short flight, crew and staff very efficient. Over all good flight experience.

I like flying first class, and United has a nice one

United airlines has the best customer experience from booking to arrival. I always fly United airlines. The mileage program is excellent

Inoperable monitor left no entertainment for 9 hours. The crew was not helpful. Food was awful.

I was not aware that I have to pay for the checked bag on the return flight. It was included in the price when I bought the ticket

how cold Sofia - Munich (first leg of an overseas trip Sofia to Boston, with transfer in Munich) not have any in-flight free snack and drink and one has to purchase those separately - at very overpriced prices at that, despite the high price of the ticket itself! I will will Ryan Air or Wizz Air and pay low-budget ticket if I wanted a zero frills flight. This is not acceptable. Coffee/tea and a mini sandwich or snack should be served on the 1st leg of an international trip with the airline.

No food available for purchase on a 2:30h flight around lunchtime… Lufthansa hand luggage policy and behaviour makes you feel you’re on Ryanair but paid three times as much

Food was terrible. Bamboo utensils are just not working out. A lot of plastic waste. Pillows and blankets were not good, a lot of static electricity. Crew did their job well.

Original Lufthansa flights were canceled and the alternative route that was offered required cab transfer in New York from JFK to Newark at my own expense. Who can refund these $218?

flight was packed, had to check my carryon bag, tiny snack bag offered, but we arrived on time and thats what counts

Expect Business Class seating to be 2 passengers per 3 coach seats, with center blocked. This is typical for flights within Europe on most airlines. Service was excellent!

They gave us chocolates twice (for whoever would like an extra chocolate - kids did!). I asked for an extra water, and I was given one. Crew was very friendly!

My mother is 87 years old and has knee problems. I have reserved a wheelchair indicating that she is immobile. For her it is very difficult to walk short distances. On arrival in Frankfurt, I was called via my mother's phone, by the female employee who had my mother in a wheelchair. She asked me how many and what color suitcases she has, which I explained. I was very surprised when 15 minutes later my mother walked out with her cane and balancing with great difficulties assisted by a young couple who were pushing her suitcase. Where was the wheelchair and the airport employee? I find this to be a disrespectful and abusive behavior of elderly people. It also raises the question of professional misconduct of the airport personnel in Frankfurt i.e. the female employee who abandoned an 87 year old immobile person by the luggage lane. I would like to inquire about the details i.e. name of that employee.

Crew was nicer to some people than others for no apparent reason. I had to get an older lady’s attention because she was too busy talking to passengers.

The flight was wonderful, especially the special assistance from airplane to airplane!
