Business Class Flights from San Francisco

San Francisco is Silicon Valley's departure lounge and the transpacific gateway where tech industry demand shapes everything about premium-cabin pricing. SFO's international terminal is United's Pacific fortress — daily Polaris service to Tokyo, Hong Kong, Singapore, Seoul, Sydney, and Taipei, plus the only SFO-based Polaris Lounge. The foreign carrier presence is equally strong: Singapore Airlines, Japan Airlines, ANA, Korean Air, Cathay Pacific, and EVA Air all operate from SFO to their respective hubs. The tech-travel demand pattern creates counterintuitive pricing: Monday departures and Friday returns (the VC and tech executive schedule) are firmly priced, but Wednesday departures and weekend returns see genuine discounts. SFO-Tokyo on JAL or ANA at 11 hours is one of the most comfortable transpacific routings — short enough for a genuine night's sleep, long enough to justify the lie-flat. On the European side, BA, Air France, and United fly to London and Paris daily, with fares running 10-15% above LAX equivalents because of the tech-heavy corporate base. Tip: SFO's Cathay Pacific First Lounge (Oneworld) and the Polaris Lounge (Star Alliance) are both worth arriving early for.
