How safe are an extra hour around KSFO, an hour turnaround and 45 more minutes flying after a long haul flight because an ATC wants to feel like the unquestioned king?
I wonder how they do that. There's only one SFO-FRA flight per day flown by Lufthansa, so if a pilot gets sick, you don't want that delaying the flight and causing a rebooking headache.
I guess they have contracts for all kinds of similar contingencies. Maybe the whole Star Alliance has one for SFO, or operators of various other intercontinental flights do.
