Finding cheap flights from George Bush Intercontinental Airport (IAH) to Tan Son Nhat International Airport (SGN) in October requires a combination of flexibility, fare monitoring, and strategic routing. Use fare comparison engines, sign up for airline fare alerts, and consider one-stop itineraries through major hubs like Tokyo, Seoul, Doha, or Los Angeles to reduce costs. Look for midweek departures, red-eye segments, and book 6–12 weeks ahead for the best Houston to Ho Chi Minh City deals. Consider nearby departure alternatives such as Austin (AUS) or Dallas (DFW) if you can combine travel segments for savings.
Tips
- Set price alerts for IAH to SGN and compare multi-airline itineraries.
- Check round-trip vs open-jaw pricing—sometimes returning via Hanoi or Da Nang reduces overall cost.
- Use flexible dates to identify the cheapest October travel windows and avoid weekend premium fares.
