I've heard rumors about SIA flying a 346 non-stop to California from SIN.
Does anyone have any guess to the flight durations of such a flight?
My guess would be 16 hours for SIN-SFO and 18 hours for SFO-SIN (if that leg is even possible).
If my numbers are correct, the flight would arrive in San Francisco about the same time it left Singapore: A 1pm take off would land in San Francisco at 1pm.
Unfortunately, the local landing time would be 34 hours after the take off locally in San Francisco (1 PM PST, Arrive in Singapore at 11pm Singapore time a day later).
It is a problem that flights to SE Asia have. They either must leave California at awful times (middle of the night), or arrive in Singapore at an awful time (middle of the night).
Do airlines look at this when scheduling long-haul flights? I know UA has all their Asian flights arrive in SFO in the morning.
