Greater Bay Airlines autumn flash: one way to Kunming or Chongqing from $30, 20% off round trips, book by Oct 21

Ten routes trimmed for a six day window.

Greater Bay Airlines has opened a two tier autumn flash sale on its official site. The larger half trims round trip fares across its network for an autumn escape, while the second tier drops selected mainland mountain routes to a token one way base fare before surcharges. Vouchers for the discounted fares are claimed in the airline's coupon centre and applied at booking. The airline has been expanding quickly from Hong Kong and this is its broadest short window of the season, with seats limited and the whole event running under a week.
