If I'm correct my choices are (don't know all the codes):

Singapore Airline
United (to NRT)/ANA
ANA
Thai
Lufthansa

Any opinion in descending order, in terms of comfort? Also, I likely won't have all the miles I need for about 3 months. I'm primarily a CO flier, but had some stranded miles I'm trying to use. I'm doing everything I can to get to that Bus Award inc:

25k/yr co-amtrack-ua
United Plus Visa
Starwood
Marriott
Hilton
Ameritrade
(any other ideas?)

Thanks
