Fly from San Francisco and see both Hong Kong and Singapore on the same trip with nonstop flights between each city for just $500 roundtrip on United/Cathay Pacific.
Flights between the U.S. and Asia will be on United and flights between Hong Kong and Singapore will be on Cathay Pacific.
This price can be found on a multi-city itinerary for travel on Mondays, Tuesdays, Wednesdays, and Thursdays, departing San Francisco between late August and November. You may return to San Francisco through the end of December.
As an example, I found this price available when using a multi-city search and choosing the following flights:
- Flight 1: San Francisco SFO to Hong Kong HKG on Tuesday, September 10
- Flight 2: Hong Kong HKG to Singapore SIN on Tuesday, September 17
- Flight 3: Singapore SIN to San Francisco SFO on Tuesday, September 24
This itinerary would give you a week in Hong Kong and a week in Singapore for $165 less than it costs for a simple roundtrip nonstop flight from San Francisco to Singapore and just $42 more than a simple roundtrip flight from San Francisco to Hong Kong.
This price includes a carry-on bag, a personal item, and two free checked bags.
Standard advanced seat selection is included.
