British Airways 787-9 SJC to London Heathrow
All Nippon Airways 787-10 or 777-200ER SJC to Tokyo Haneda
Historically/realistically, SJC had flights to Shanghai on Air China’s A330-200 (sub with 787-9), Lufthansa A340-300 to Frankfurt (sub with A340-600 or A330-300).
Hainan Airlines flies SJC to Beijing Capital, but a Hainan livery isn’t in the sim.
SFO’s much more flexible.
You could try SFO-DEL with Air India’s 777-200LR or United’s 777-200ER/787-9. Here’s some scenery you’ll probably encounter on the flight:
Overall, this is SFO’s route map. There’s a ton to choose from, or you don’t have to follow these real-world routes.
