Flight Distances from San Francisco to Major Cities in Vietnam

Because Vietnam stretches over 1,000 miles north-to-south, the great-circle distance from San Francisco (SFO) varies significantly depending on the destination airport. All routes require at least one stop (typically in East Asia), so actual flown distance is longer.
