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

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.

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

Leaving at 7 when scheduled to leave at 4:20 - you tell me. Understood there was a ground stop. Then having to "reboot" the plane because of a lighting strike, also understood. But basically the flight was a "clusterf#$%".

No drink service but there was no N/A as an option to choose. Seats were extremely tight. I am under 5.5 and I bumped my knees have no idea how taller people could manage.

My flight from Honolulu (UA 1221) was on a very old 757, no video monitors anywhere. If you wanted to watch a movie, you needed to do so using the United app on one’s phone. WiFi was $8 for Mileage Plus members; I demurred, choosing to spend my time reading a novel using the Kindle app on my Samsung S26. The meal was okay … Breakfast on any domestic airline is so-so as a rule and this one was no exception. The best part of the meal was the fruit plate and the warm croissant. The highlight: The flight left on time and arrived early.

Flight delayed, last seat on the plane, no arrival Gate available due to the plane departing late
