There’s an offer out there on the Hong Kong site for United Airlines offering double redeemable miles when an itinerary includes flights 895 and 896, the nonstop segments between Chicago and Hong Kong. Ticketing is required before October 31, 2011 for travel between September 1 and October 31, 2011. The bonus can be earned a total of three times during the travel window. I don’t see anything in the full terms (below) to restrict the bonus to non-U.S. Mileage Plus or OnePass members, but the terms do state “members must purchase and complete at least one paid qualifying roundtrip between Hong Kong and Chicago.” It seems to infer that travel should originate in Hong Kong, but given the sometimes inefficient programming in place at United, it certainly wouldn’t hurt to register and hope for the bonus if you’re on 895/896. My registration moments ago appeared successful having been given the following confirmation:
