I am also former Houston resident with experience travelling back to IAH from abroad. Seems I am in the minority with period for posting miles to OP. Could be explained that I live in SE Asia and travel from home to US instead of vice-versa. Certainly, my miles posted within one week. I have no experience with NW, but my expectations would be uniquely low. UA is probably above NW, but not much. Against these, Eva probably stacks up pretty good. My destination has never been TPE as I use Taipei, Hong Kong and S'pore as gateway cities, but I would encourage anyone who is travelling to look at CX, SQ, Thai for travel to this region.
