Oh interesting, I've never read about 2BM for award tix before! Will think about giving it a try... I guess worse come to worst, I can just change the tix for free on CO.
Yeah, I'm trying to do award bookings for my parents. They're planning on SFO-JKT-HKG-SFO, but their HKG-SFO legs will be on different dates. It would probably be best just to PUTPAC, but wanted to make sure what's possible before I call.
