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

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.

Had to cancel and rebook, KLM connection was cancelled prior to departure, ended up flying to Munich on non-Delta carrier.

The crew were unprofessional with a racist element. I was physically abused as well from one of the crew members

They forgot to serve food and the crew was very unfriendly. Never experienced such a bad KLM flight. Usually fly from Toronto. New York was different.

Over 1 Hr delay. No APU so no AC on ground. Plane was hot during boarding and then they closed the doors over 20 minutes before engine start so interior of plane was steamy hot and stuffy. Could have been helped by opening doors until ready to depart.

My flight was delayed by 6 hours then I missed BOTH of my connecting flights, I then had to stay in the AIRPORT at JFK because soooooo many people also suffered from missing flights and there was no hotels available. I would like to be compensated for this experience! I had to stay in the airport for over 16 hours!

Cabin crew were excellent, very proffesional, polite and friendly, in flight snack was underwhelming, a packet of cheese biscuits, im sure KLM could run to a sandwich!

Overall very positive. Boarding was quick and organized. Cabin was clean and seats were reasonably comfortable. Cabin crew was excellent and the meals provided were also of good quality

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

Pre-boarding seemed tom happen at the same time as Business Class - I thought the idea was to allow people who needed extra time to board without interference from other boarding types, but I guess that's how they do it at LAX.

The good: we liked fast boarding, the departure and arrival on-time. The not-so-good: The crew should learn from their sister-company Swiss with whom we took the flight to the US. Austrian onboard personnel need to smile more and provide a better service. Food was okay, there was the usual issue with “no more chicken” by the time they reach row X 😕. We did not understand why the crew collected trash so randomly and inadequately. We missed the free internet for messaging which was privided by Swiss as well. Hope this feedback helps.

They should be kind to the people Food is always plain pasta bread is from the fridge they don't even warm up Seat is so uncomfortable body hurts

I am very satisfied for choosing that Airlines! It was my first time but the everything went smoothly! Thank you!

This is truly the worst travel experience of my life. The UK ETA program had a technical failure, and I was stuck in limbo for 24 hours, unable to board my flight and unable to navigate anything in my itinerary. I had to rebook an entirely new flight and I’m now out doubled the money. Unconscionable.

OK, would prefer some meat for dinner, not just pasta although was tasty. There was only one dish, no choices

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

It was a great experience. The aircraft is a bit dated but other than that it was great.

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.

The flight was late. We accommodated other missed flights, and the plane was full of people, without space to store carry-on luggage. They lost our checked luggage for the entire flight and delivered it after two days.

First Flight got delayed had to get rebook for another plane ride to connect the next day the process was not helpful at all had to figure the whole processs myself poor service plane was small and customer service was horrible will not fly this airline again

Overall it was good. Food was bad. I ordered gluten free vegetarian meal. But I got gluten free chicken for my long flight from Seattle to Istanbul. I don’t eat any kind of meat. Second meal I got eggplant with meat which I couldn’t eat. I don’t understand why we can’t get gluten free vegetarian meal for a 12 hour flight. I eat the bread and that was it.

Bough tickets with luggage, but made me pay at Airport as well

A great airline, no complaints at all. My experience with Cheap Tickets was very disappointing however. Two hours after purchasing the flight they called to tell me that the ticket price had gone up. I’ve never heard of such a thing. That is called false advertising; I will never use this ticketing service again and will warn all friends to never use it.

The food served was frozen salad and hummus. The hot meal was fine. Crew was doing bare minimum

I enjoy flying with Turkish Airlines and such good hospitality among the crew memebers

I did not like the quality of the food and there was no snacks offered between meals.

A little bit more comfort. It’s tight space around the seats. But all else is great and a smooth flight!

Total chaos with baggage check in…..rude staff in Seattle. And faulty seating/entertainment systems. Unable to log in to WiFi desperate being a member. Kept on getting errors. Never again. Definitely not what’s expected from a Star Alliance member airline.

As far as I remember I've selected and payed 65$ for a seat on the aisle. The seat selection got lost and the location was bad.

Premium economy was worth it. Great seats and good food.

Flight be on time would be a good start. Then train your flight attendants to be attentive and friendly. This time they completely forgot my row for the measly snack! United, do better!

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

Very comfortable seating and the Flight staff were very attentive. The premium economy section that I was seated in was very clean, updated, and well appointed. I would highly recommend flying United Airlines as this experience was better than the Japan Airlines business class that I flew several months ago.

United needs to step up their game. Delayed flight leaving Seattle, San Francisco. Older aircraft, not very comfortable.

Had to cancel first flight because Airporter Bus took over 3 hrs to get to airport which resulted in an extra $378 dollar fare . Is there anyway I can be reimbursed for initial fare since it was not my fault? Sent from my iPhone EJ Ledet

Delayed by 2.5hrs any longer and they would’ve had to honour their own policy for breaking their own rules and regs. Not cool, especially when I have an infant child that needs to stay on a routine and they get schedules.

They had three choices for snacks - but you could only have one - and they ran out of the dark chocolate before they made it all the way down the aisle... Packed flight - limited service.

They opened my checked bag and even though my lock was tsa approved, they loose my lock and left my bag just like that. Incompetent people, very upset about it. I’ll try to avoid traveling with united

We fly to Ecuador frequently. Checking in is usually a hassle because most United agents take some time before they can verify that my passport doesn't require a visa to Ecuador. This time the process was even longer due to the cyber attack. But she was really nice to us. So glad we brought plenty of snacks to supplement the 3 flights from SEA to GYE.

The new buisness class pods are 100% worth it. Loved it.

The flight was cancelled, so why are you asking me how the flight was?

It would have been nice if my luggage had made it onto my connecting flight as well. Now I have to wait for my luggage to be delivered and that might take a while, which certainly put a damper on the entire experience.

Biggest gripes were that the seats were extra narrow as the 4-in-the-middle taper down. As with most flight, too little leg room hurts my aging hips. Also changing the flight time to 3 hours earlier meant that we had a terribly long lay-over in one of the world's most boring airports

German crew were very kind. Food was okay but can be better, especially bread was not good, Garbage collection was very poor.

Great! Great staff, great food, great flight :) Keep up the good work!!!

It was good. Nice entertainment selection to keep me busy for the timeframe I wasn't sleeping. Professional, courteous and attentive crew.

They lost my bags and I didn't get them for 4 days after. This also happened to about 30 other people on my flight from fra to MAA (I know bc we were all filing claims in line together from the same flight.)

Flight took off arrive Frankfurt fine ... and then the Pilot parked the plane for 20 minutes while waiting for a steps vehicle to arrive so we all could deplane. This caused us to miss our Naples flight by 6 minutes while running to the next gate.. We are aware of 3 others who also miss their flight. Lufthansa Support said "why miss your flight, your flight arrived on time?" We explained, they provided another flight many hrs later, no meal voucher because our "flight was ontime".

They help we received from the check in crew and boarding cr
