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).

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.

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

Austrian airline they cancel my fight , and the couldn’t give me flight , they said only available flight 4th and after , I sacked for refund, even from you KYAK , and tell now no any refund , because what happened I lost more money because I have to stay in hotel and then I buy new ticket

Everything could be better.Call center is so bad.You can't fix anything with them.

waited standing in security corral for an hour with no updates

Crew attendants attention to the travelers. Good food. I always fly with Turkish Airlines

The sleeper seats, the staff, and the food was truly delicious. I loved the mocktail options.

Great food, and lots of it. They made us come to the gate two hours before the flight and you were stuck in the enclosure until you boarded with no bathroom or food or drink. My seat in business class was very claustrophobic, I could barely get into it and a large board blocked the window and made it even more claustrophobic

Cabin was kept very hot and it was uncomfortable. Entertainment system did not work at my seat. Crew and service is fantastic

The crew on this flight provided exceptional business class service to me.

The airport staff never announced that boarding has started. Both at iad or Islamabad or Istanbul.

The airline could improve its business class seats and privacy in line with its competitors.

The seats have to be one of the worst when it comes to comfort and you have to scramble around to out your handbag in the overhead. The food is still awful. Definitely will not travel on Turkish again and wouldn’t recommend it to anyone for sure.

Worst boarding experience, flight extremely delayed causing super tight connect and deplaning was a disaster as ppl were pushing and shoving to get off. Then after flying over 8 hours had to get off a job to next flight. Limited beverage service in Business class (water or white wine) no food. The plane was very cold (temperature) so uncomfortable

- delayed because video screens not working - delayed getting a gate at DCA Just continued bad experience IAH to DCA.

The business class service was very good. The crew was helpful and the food was enjoyable. Boarding was well organized.

Entertainment was great. Seats were good. They did not have my pre-ordered hot food product available but did comp me something cold in place of the item.

No water or beverage was provided. I had to ask for water. The sole flight attendant had more interest in selling the credit card. In addition when we got to Dulles the plane and gate were misaligned and it took at least 15 minutes to get off the plane.

Flight was delayed almost an hour because the cleaning crew broke one of the bathroom doors.

When we boarded we were treated with care and it never stopped. Got towels before breakfast and after snacks was a lovely touch!

The flight crew was the worst I've experienced. If they worked for me, I would fire them immediately. They never smiled, they seemed angry and avoided passengers as much as possible. The food was not edible, and my luggage was lost. I will never fly United again!!!

Fought with Lufthansa was poor, seats are uncomfortable, food was bad and luggage did not arrive to IA

Awful!!!. I do not recommend United. The flight staff are unhappy and don't attempt to make the passengers feel comfortable or welcome. The food is not edible, and the seats are miserable. My expensive luggage was destroyed, and the ticket prices are too much for the experience.

Economy plus on a long flight with Lufthansa was wonderful. Service starts with a pillow, blanket, slippers and care package waiting on your seat. An it just gets better from there.

The Linate Milano flight was delayed. Landed at Frankfort at 12:10. Then took the bus on the tarmac and the bus ride was about 20 minutes due to the airport traffic. Got off bus went to passport control, used the kiosk scanned passport, took photo and finger prints and proceeded to wait in line. I asked the attendant that I had a connecting flight at 12:50 his respond was you have to ask the other travelers in line to let you go ahead. There should be a better system. Passed passport control and the gate was at Z69 to the other end of airport. Ran there out breath, I was last person to board due to a mechanical:electrical issue plane took off 2 hours later. Lufthansa need to a better job with international connecting flight. A 1-15 minutes is not enough considering the doors typically close 15 minutes prior to take off. So the window is reduced to 1 hour with all you have to go through with a slight delay it is not enough time. The crew on the flight was excellent and received exceptional customer service.

Horrible. Would not assist w hotel or new flights when Catania leg canceled

The entertainment system was not working, they tried restarting it couple of times but it did not fix it. We were told to contact Lufthansa costumer service after the flight for some kind of reimbursement. When costumer service was contacted I was told no reimbursement for entertainment system malfunction per policy.

I was never able to use this flight. I booked my flight through KAYAK, using cheapfaresflights, and the agency did not book the ticket correctly. When I went to check in for my flight in Rome, my details had changed. My name was incorrect , and the itinerary was not what I had paid for. I was unable to board the flight and I had to purchase a second ticket at considerable expense. Unfortunately, no one at KAYAK or Cheapfaresflights was able to help me. They both shifted the blame on United Airlines, United Airlines was able to provide me a full detail that the error occurred on the travel agencies side. I consider this fraud and will pursue it further.

Cancelled 90 min AFTER Departure! We had to deplane and wait another hour plus for the flight to be shown as cancelled for the customer service team. There were many many angry customers.

Bulkhead seats should not be an extra charge. They are extremely uncomfortable. And we missed our connecting flight due to slow luggage retreaval.

Lufthansa flight LH04414 from Munich to Washington DC, was fine. Efficient and safe!

Bumpy ride, not Lufthansa‘s fault. Crew managed a situation over a back rest to far down well. It was two iles behind me. The person putting the seat down, against the other person’s knees, was quite rude and belligerent and needed to be told in a no nonsense matter to stopp. Male flight attendant did good job.

Had a few open seats and could use it for a great rest ful journey
