Very comfortable (upgraded to business class). The audio on my screen didn’t work, but I managed to play the audio through my phone while watching the screen.

Flight was late as pilot crew had to land at different airport in their previous flight. Passengers boarded and had to wait for pilots inside plane. Series of incomplete and unnecessary announcements by an annoying voice, rather than complete, informative announcements.

Breakfast was not loaded at SFO due to catering company change. Seems like a major airline at a major hub would have thought of something else or warned passengers to pick up food before boarding a 3 hour flight.

Boarding seemed to be organized bedlam. For what ever reason, preboarding took longer than 20 minutes. Made the plane 20 minutes late taking off. Luckily we arrived on time. Flight crew seemed very friendly. Only slight turbulence.

They hired a new catering company the same day of my flight. They botched the job by not delivering the right carts and after THREE HOURS waiting, the flight crew timed out (flight was 19 hours long and FAA rules state crew can’t work more than 14 hours long). So they CANCELED OUR FLIGHT!! Worst experience ever. Avoid UAL at all costs.

The personnel were professional and friendly. The Boeing 737 Max 9 is too claustrophobic and was very warm at both airport gates, and still warm in the air.

While the staff was pleasant and helpful, the following observations are for your awareness. There was some delay on the tarmac on take off and landing. The paid lunch/food offerings were limited. Entertainment was only available on WiFi at a cost.

get E+, a must for 5 hours flight if you are tall

Liked fold flat bed. Didn’t like having no window. Didn’t like poor choice of food and being served dinner very late, hours after take off of a 7:40pm flight. Servers not friendly. Food horrible in business class.

Everything is good except the dinner and breakfast. The sandwich is very delicious. Toilet is clean, I only use one of them. Flight attendants are very nice. 👍👍
