I wanted to give them a five‑star rating across the board, but they lost my luggage, and that really affected the experience.
8.0 ExcellentNikola, Oct 2026
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 got a fortunate upgrade to First Class. The trip was outstanding in every regard, with a particular shout-out to the crew, who were outstanding.
Only the dishtray thing. The leg room was reasonable but the trays sitting too long and space small no space with food plastci cover and utensil wrappers. It got cluttered fast. Perhaps provide tiny trash bags?..
Boarding was very slow and unorganized. As a result we were delayed for 25 minutes crew is not friendly. food , entertainment and service was mediocre I bought in flight internet and paid $42.61 it did not eben worked after 10 minutes and no one helped I would like a refund on that please
Excellent excellent flight! I’m sure it helped that the turbulence and the weather cooperated, but the staff was wonderful. The legroom was perfect and my husband is 6‘1“ and he felt perfectly fine. Best flight I’ve taken in a long time.
The transfer was awful, everyone was running to catch the flight, there was no information on the process. We git to the gate and the boarding was late and had to stay in different lines but there was no guidance. The flight was late and uncomfortable, probably one of the worst flights I have been on. The luggage was sent to a different terminal and still did not make back to us.
The awful part was the customs delays at ZRH. The good part is the flight was delayed long enough to accommodate. The flight itself was fairly comfortable.
It was on time and we arrived safely—that's a good thing. Other than that, my son's seatback storage pocket was ripped and couldn't hold anything, and his footrest was stuck so he couldn't use it. You pay extra money for allegedly more comfort, but the plane was old and the seats were broken. No drinks were offered in the beginning like in other premium economy settings, no hot towels. It was really basic and nothing more than economy other than three times the price. Very disapointed. My food tray was VERY dirty—I couldn't even eat anything after seeing that. I will try to avoid SWISS in my future travels
Slow boarding, late departure and arrival. Very good crew and free messaging over WiFi but outdated electronics and seats
Overall good solid airline but got “burn” with my check in the “free” laugage that weighed 8 kg.
The service was impeccable both ways. I’m very happy to have had the opportunity to fly Swiss Air.
I couldn’t give an honest evaluation, because the Houston airport has a problem and I was stand up for several hours and after a long trip from Munich I feel really very tired
It was very good. the food was varied and tasty, the movie was the same, maybe I would recommend changing the movie selection every month because my flight to Amsterdam was in September and I came back from Munich en October they are flights so long and we need something to see. But however I liked flying with United
A couple flight attendants in business class had bad attitudes and provided poor service. They did provide drinks or refill drinks. They talked to certain passengers for long periods of time and ignored others.
I especially enjoyed having a lightly packed flight which enabled me and my wife to occupy a three seat area with nobody in the middle seat.
Fantastic experience once again flying with United! There was great communication from the cockpit and one of the flight attendants went out of her way to get my two little kids some special treats which elevated our travel experience coming home.
The business class service was very good. The crew was helpful and the food was enjoyable. Boarding was well organized.
1) United economy seats barely recline. 2) I have yet to get United WiFi to work, after numerous flights.
Flight attendants need to know their plane. Seated in first row yesterday. The seat had about a 1 inch recline that was not adjustable. I don't appreciate being awakened to raise a seat that can't go any further forward and such a small recline is either irrelevant or the plane needs to be repaired. Not the way to treat any customer and especially the ones who have paid that level of money for the seats.
The experience was good overall; however, my United Airlines Mileage Plus Account didn't reflect my flights to Houston from Newark. In essence, my mileage rewards points do not reflect my actual travel. This should be corrected.
Delayed - leaving, delayed getting to the gate at destination. What should have been a very easy flight and experience was not.
Inflight food quality is definitely declining. Only one hot food was served and rest of were boxed meals. That’s not how was done before. Better to fly Asia or Qatar carriers for better service.
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.
Loved the towel at the end. Service was frequent and perfect.
Horrible. Would not assist w hotel or new flights when Catania leg canceled
They left a little late, contributing to our missed flight.
Absolutely horrible. We missed both of our connecting flights from Frankfort due to the new border control lines. Lufthansa had us running and walking around the airport trying to rebook. They were not prepared to offer us a hotel room for the night, but finally relented when I said I was done with Lufthansa, most were not so lucky. I also put put of the blame in Kayak. You need to update which connecting flights you are offering to allow for more time to deal with the mess that is border control in the EU.
Cheapflights did not forward the payment for seat assignments, and my partner and I were separated and given center (B and E) seats. Will be requesting a refund.
Good communication via the app regarding the delayed departure. Uncomfortable seat for tall passengers. Could not straighten my legs.
roomiest flight in economy I've taken in years. Excellent experience!
