For example, we found seats departing San Francisco SFO on Monday, November 5, returning from HKG on Monday, November 12.
Other dates are also available for travel from late August through December. Travel from San Francisco is available on Mondays and Wednesdays. Travel from Los Angeles is available Mondays, Tuesdays, Wednesdays, and Thursdays.
These prices are even lower than what is advertised in the Southeast Asia sale on Hong Kong Airlines, which is valid for purchase through May 31. Since these low $300 range fares are unadvertised, prices may jump at any time.
Seat selection is not included in Hong Kong Airlines' lowest fares. If you favor other carriers, Cathay Pacific and United have $418 roundtrip fares from San Francisco to Hong Kong, while Cathay Pacific and American have $458 roundtirp fares from Los Angeles to Hong Kong.
Update May 25, 2018: Cathay Pacific is now matching Hong Kong Airlines and selling tickets for $348 roundtrip from San Francisco and $388 roundtrip from Los Angeles, with departures from the USA from August 27 through December 6. Return through December 26.
