So UA isn't completely matching, but a couple sample dates I've seen are now ~$490 IAH-HKG, so they've come down ~$50 in the past few hrs. Effing nuts. I'm thinking of booking one to requal for Silver and go have dinner in HKG. IMO well worth the extra $100 over DL because it's a single connection vs double connect on DL and shorter travel time. Many of the DL flights have few hour long connections in SEA.
