  • January 2027 is the cheapest month to fly over the next six months, with round trips from $566; September 2026 is the most expensive at $774 and up, a difference of $208 per traveler.
  • Departing on a Tuesday averages 17% less than a Sunday on this route. If your dates are flexible, shift the outbound by a day or two and check the calendar view before you book.
  • Book 2 to 5 months ahead for the best fares; long-haul seats sell out earliest for summer and holiday travel.
  • Hanoi is 14 hours ahead of San Francisco. Expect to lose 14 hours on the clock heading east, so an overnight or late-afternoon departure tends to arrive at a more usable hour.
