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.

The temperature on the flight was unbearably hot and they were unable to serve waters and did t make any adjustments. This impacted us both when leaving, we pushed away from the gate but didn’t taxi for takeoff for awhile then arrived ‘early’ yet were stuck in the plane for longer than we should have been.

Terrible - the flight was delayed taking off after boarding. Then the flight circled lga before landing. Significant delay

I booked a round trip with Delta, and each of the four segments was sold off to three other airlines. All four were late or cancelled, so I had to troubleshoot with three different airlines, NOT Delta. In fact, even though I had paid money to Delta, they could not help or troubleshoot anything. Not nice.

The crew performed the absolute minimum. The plane ran out of toilet paper and there was 2 hours of flight left of an 8 hours international flight. The food was a average

The actual flight was smooth and we arrived earlier than expected which was great. The flight attendants gave unclear instructions and were rude. They seemed overwhelmed or flustered for the flight. Inflight service was delayed and unsure why.

Everything went smooth from check in, thru TSA, then boarding, and a smooth flight to ATL.

There were weather issues in the area apparently; however, that was not obvious from what we saw outside of LaGuardia. We were delayed leaving (which I understand); however, once we were on the plane we didn't leave for a long time. It may have been two hours?? - all I know is that we sat there for a long time with no information as to why we were not taking off. Finally, after 45 minutes to an hour (maybe?), the pilot gave us an update that no planes were able to go in the our flight path direction (or something like that) due to weather. There was nothing additional added. What does this mean? Why is this? What are the options? When will you give us another update? There were no updates for maybe another 30-45 minutes. There was no explanation as to why we couldn't be rerouted to avoid the weather. We had no information at all. We just sat on the plane (for about 2 hours) with very limited information. All I would have wanted is an explanation as to what was going on. Tell me there is bad weather coming our way. Tell me they are working to reroute us around it (which is what they did). Tell me SOMETHING.

Crew and support were very good; lounge was very good. Seat was narrow and very close to other passengers; lie flat is more complicated and exposed to the aisleways.

My 4pm flight did not leave until about 10pm. I did not enjoy this experience.

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!!

Airplane is not very clean, food quality and taste was not good. Lufthansa used to be good but nowadays went down. Overall experience is just okay, wouldn't fly again, prefer Turkish airlines.

I missed the flight due to maintenance issues. This is the second flight I’ve missed in four days because United allows such little time between layovers. Very disappointing

My return flight to Honolulu (UA 1170) was on a 777-200. I’d forgotten the weird seating arrangement in first-class (2-2-2); I was in 1B, so I faced the passenger in 1C. Unfortunately, there was a problem with the flight computer, so we left LA an hour late (6:05pm). The meal I chose was Korean BBQ Glazed short rib. It was served with a nice salad and fried rice. This meal was better than breakfast on the outgoing leg. All in all, a decent flying experience. Ratings: 777: 3.75, food: 3.5, service: 5 (out of 5).

Food was not Good Nuts came very wet & not tasting Good Main course I asked for Steak they got me Chicken because they don’t have more !!!!

It cancelled and we were unable to catch our connecting international flights.

We couldn’t take the direct flight back home in Florida because the flight in Palermo was delayed flor long time and keep us inside the cabin without moving the plane. The plane from Munich to Orlando was still there when we arrived to the gate but they said it was late for us to board the plane. We rushed the most to get there. It was a bad experience and got back exhausted and with pain in all muy body. We are seniors 72 and for us was very bad

Terrible service - they don’t want to be there and bad food. Entertainment system in economy from the 2000s

I did bought anything… I don’t understand how this book appears to me . Ridiculous

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.
