Apologies for the delayed response, but thank you, everyone. The main reason for asking is that when returning to the UK on vacation, I nearly always go through LAX, and most, if not all, flights from there have the upgraded suite. I often spend a week in the UK. Then a week in CA on those trips, but due to a change in personal circumstances, I'd like to go via SFO, as I know SoCal well. It's become a bit boring, so I would like to re-explore northern CA without having to deal with taking an extra day or two off my vacation time, dealing with extra flights, or long drives from LA.
