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.

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.

Flight was delayed. Can happen. But the info on the website and app said that flight was cancelled which was not the case.

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.

Both legs on the way were smaller planes, each had a mechanical issue causing a delay

Delta exceeded my expectations! I am beyond satisfied. Thank you!

Flight was on time! That's the most important thing for me.

Delayed flight. Dirty seats, dirty seat belts with food stuck on it from previous passengers maybe. No one cleaned the seats or flight.

The flight was delayed and knowing I was going to miss my connection, nothing was done proactively to try and get me rebooked. It was an act of congress to do so. This is not on the crew, but on the experience itself

No headphones, forced to sit in another seat that I did not book, had to check my carry on when I boarded the plane I saw backpacks and other non carry on items stuffed in the carry on holder! Horrible experience Wi-Fi did not work either

Sat in the tarmac at O’Hare for 65 minutes. This is a regular occurrence for delta at O’Hare

Delta is getting worst by the minute. Where this was at one point my only go to airline, it has become like a budget airline

All was fine. Small plane so no food or entertainment.

Lady Pilot was perfect in every way wheels up to wheels down communication, professionalism, excellent on time departure and on time arrival, excellent communication! Fantastic job with Superb attitude!!

Great Brasilia aircraft - not a Boeing 757 like the next part of the flight. Flight from MCI to IAD was great, on-time, comfortable, did I mention that? The flight from IAD to EDI was painful. One of the reasons I won't fly United again? Boeing 757, with a seat pitch and material that was horrendous. Worst aircraft ever, made worse by United sardine-can tight seating. Oh, and the connection window, 45 minutes, really? At IAD, in different concourses? What idiot came up with that flight scenario? Happily, (for me and my travel insurance people) the flight was late (reminiscent of American Airlines). The crew was professional and courteous.

Crew was great. Seats are cramped and uncomfortable and I’m a small person.

Awful. Delay after delay. And then again on the tarmac.

WiFi was slow as compared to trip down. Maybe because it was a night flight and more people were using it?

Excellent except for the 2 screaming kids who wouldn’t stop crying and screaming for the entire flight but what are you going to do? The flight was early- good experience

Kept changing the takeoff time and the moved it up so arrived when boarding had already started. Then sat waiting to taxi in for a long time

great starting with the business Class that's was Amazing . thank you United Airlines and brussels Airlines

My email and credit card were used fraudulently for this trip, so no, I did not take this flight.

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.
