Other than the airline changing my aisle seat to a middle row, all else went well.

Other than the airline changing my aisle seat to a middle row, all else went well.

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.

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

Very kind Lufthansa agent somehow gave us all no charge extra business class seats and helped us get home rested and happy.

The lounge was not accessible because it was located before the passport control, and backtracking was impossible.

Flight was great. Almost miss my connecting flight due to late departure from Haneda. Had to run all through airport in Chicago to make the flight. Experience was great for 1st time flyers using ANA Airlines.

the seat has a problem. the back had a hole.

The back to back mechanical delays from Denver to San Diego and then on my return flight from Denver to Great Falls it added extra time both ways

Really old place. Not as clean as it should be, tray tables needed better cleaning. The items, trays and some other items need to b6 engineered. Anything task you or crew may do is incredibly load, seriously engineer for quiet smooth, easy. Just opening and closing the tray table is actually dangerous and can easily injure a finger. I'm sure it happens as it happened to me! First time I used United and likely will be the last!

The website check in was poor. Baggage fees were in US dollars but registered in Canadian dollars. The site would not accept my credit card. Scanning the passport was the worst. Someone from United needs to try the process. I’m not a novice with tech and I have to say this was a bad experience. Everything else was great.

Like the fact that the boarding was expedited. But the delay and chaos around the onboarding was not appreciated.

It was hot and not as comfortable as the flight to Chicago. Must have been a different plane that needs to be worked on or replaced.

Short flight, but no drink/snack service. The flights both going and coming were delayed.
