Strategies to find cheap flights from San Francisco International Airport (SFO) to Tan Son Nhat International Airport (SGN) in November include: set fare alerts for SFO to SGN routes, search midweek for lower prices, consider one-stop routes via Taipei (TPE), Seoul (ICN), Tokyo (NRT/HND), Hong Kong (HKG), or Singapore (SIN), and be flexible on dates. Use price-comparison tools, clear cookies or use incognito mode, and book seats 6–10 weeks before November travel for the best balance of price and availability. Sign up for airline newsletters from carriers serving the route (EVA Air, Korean Air, Cathay Pacific, Japan Airlines, Singapore Airlines, Vietnam Airlines, United) to catch flash sales.
Tips
- Compare total travel time vs. fare; longer layovers can greatly reduce price.
- Consider nearby departure airports (Oakland, San Jose) only if cost savings exceed ground transfer hassle.
- Look for multi-airline itineraries that combine lower-cost legs through Asian hubs.
