Made it home safely. I left Changi Airport at 6 pm Singapore time on Sunday, and arrived in SFO at 8 pm PST. So that’s about 17 hours’ travel time, I think.
Since everyone put their windowshade down right after takeoff, I was in darkness the whole flight. So in a sense I missed a day. Kind of strange, but probably not as dislocating as having seven hours of daylight.
