very nice blankets and comfortable seats. great service. Great flights.

great experience just at the end, we got in early and there wasn't anyone at the gate for 30 min so we had to just sit on the tarmac

Generally Good. Outbound flight was marred by a continuously s creaming baby. Fortunately the flight was only 90 mins long it would be nice if people traveling with small childres could be centered in one part of the plane. Also, you need to adapt your servey to include a "not applicable " option for things like food and entertainment, which are not offered on shorter flights. I fily Alaska by choice as given all the cirumstances, I fel\el you do a good job.

I was seating in 26A and the children in 27A and B were kicking me non-stop. They kicked me for hours nonstop and the parents refused to get off their phones or correct them. I kindly asked multiple times and got screamed at by the mom that her son is disabled. I told her I get it, but that I matter too and she is responsible for her child. He then kicked me so hard my drink spilled. Not one crew member or other passenger said or did a thing. It was so horrible.

My very first, first class flight! Loved the comfortable seats, foot rest and beverages. Did not have food due to short flight. Crew was very friendly!

Birding was slow. extremely slow; please do experiments on efficient plane boarding experiences; especially regarding passengers that pass their seat number…

This flight was all good. It was packed, but it took off on time and there were no problems. It would have been nice if they'd checked our bags for free, as they sometimes do.

Pretty smooth ride!… a little tight in the back and would’ve loved to had a movie screen… couldn’t beat the price to the West Coast!

I like not much people. Could tell the kids to be quiet.

I liked everything except, I left a brand new Switch 2 on the plane and talking to anybody about it is nearly impossible. I had to fill out a form and hope they get back to me in the next 2 weeks. I really hope they contact me. I saved for that thing for over a year and my son is heart broken.

Some crew were unfriendly or in some cases just straight up rude.

Booked through Kayak Business, had a seat in middle and towards back due to booking rate, not comfortable.

Was great in general, try to respect time and excuses when slight changes have been made, appreciated!

A long delay. Don't travel late in the day.

Super friendly with lots of drink options an entertainment. Friendly crew.

Standard flight with a drinks and a snack- overall very quick flight. The flight attendants were very strict, bordered on rude.

Outstanding service, efficient & friendly crew, flight was safe, comfortable & on time

United Airline crews were very friendly and very attentive. 12 hours flight was gone like in a shorter one.

Delayed - weather wasn't bad at either end. Also sat on tarmac in ORD.

Food was surprisingly delicious. Space in the seat is horrible when the seating front is reclined. Movie offerings were terrible. Crew was friendly and helpful.
