UA3888
I am currently on this flight, heading back to SFO.

PlusPoints upgrade cleared at the gate. Not sure why it took so long to clear, as the flight is basically empty.

No PDB.

No use to ask for pajamas: thought the flight length would qualify, but alas, I have yet to even see a Flight Attendant?
Maybe the newest 2024 UA Flight Attendant safety policy is already in force: "Flight attendants are there for your safety only, and will remain in their crew-rest cabins for the duration of the whole flight, unless there is an unlikely event of an emergency."

There are no meals offered either, but that is about on par with the inedible stuff United normally serves, so no big loss there.
Overall about the same flight experience as usual...
