Thanks guys that was very helpful.. I was able to view seat maps and select seats for 2 of the 4 flights. I noticed at CO.com this morning seats were auto assigned overnight as well for all but one flight.. ICN-SEA.
Now my next question is..why? For HKG-ICN-SEA on 11/23 it won't even let me bring up a seat map to choose a business class seat (A330 2 class). A window was assigned on HKG-ICN, and no seat at all was assigned ICN-SEA. On ExpertFlyer HKG-ICN is C9 D9 J6 D6 and ICN-SEA is C5 D5 J5 D5 so it doesn't appear the flights are sold out. Plus if they were that full why would they sell a saver award ticket!
Does Asiana block a ton of business class seats until closer to the flight? I really want aisles on all legs if possible and it just seems strange every seat is taken.
