Cathay Pacific via DealBase discounts select Cathay Pacific Roundtrip Flights to Asia with prices starting from $569.77. (On the Dealbase landing page, click on "Cathay Pacific" in the main paragraph to see this offer.) That's tied with last week's mention as the lowest price we've seen for Cathay Pacific routes since January, and it's the best deal we could find for select routes by $3, although most airlines charge beyond $600.
