Ok-here's the prob. I am going IAH to BKK at years end. Will be 19K miles. That would make me silver on Continental OR NW.

What to do? Any opinions? I use my miles for international upgrades on cheaper fares (I ALWAYS fly discounted-but I fly at least once a month-Continental must not think my $ is as good!) so I think NW might be the better choice to make the elite pgm.

Thanks--first time poster, long time reader!
