I did, in fact, confirm that the flight was going to Oakland when I checked in. They never mentioned changing planes, etc., etc.
And--I'm no lawyer--but the fact that it was booked on the United site, serviced at United gates, etc., indicates a level of involvement if not endorsement on their part.
I'll let you know their response when I write.
