The pilot was late so we didn’t take off til almost 2 hours late.

No seat back entertainment. And app had a hard time getting entertainment loaded.

It was great with United overall except for two things. 1) It was a 5-hour flight and we were with kids, so we were asking for extra snacks. They were extremely reticent to dole them out even though there wasn't any meal and the kids were starting to hit their limit towards the end. 2) Baggage didn't arrive until 80 minutes after we landed.

We had to deboard 2 times due to maintenance issues. They changed the plane, and then we got deviated to LAX due to maibtenance issues on the other plane, had to sleep at LAX and los a full day.

Staff was rude. Didn’t give water for 2 hours. Worst service

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.

We took off an hour late due to arrival airport not having enough gates. That was followed by 1:30 wait to get our bags delivered for the entire flight.

Checkin was painful and slow! Lady didn’t seem to know what was going on and couldn’t explain the delay. Seemed ahe couldnt see the computer scree and we couldn’t hear her talk through her mask.

It’s a service to take you from one point to another. No frills. You want it, you take it. It’s upon you to bring food, reading material, games to play, movies to watch, etc. The wifi onboard never works - so you cannot even listen to any podcasts, music, or get updated news feeds. The toilet is a mess, and a four flight does not need any hygienic interventions when people either splatter their pee all over the seats or on the floor. It’s a monopolized service and so smile and bear it.

Great crew, smooth flight. 30 minute delay on the tarmac with no status updates or information from captain. However, that was the only negative on the trip.
