For those of you who have transitted NRT from BKK on the way back to the US, do you think a 50 minute layover is workable for bags to make it to my next flight? I might have to head back to the US a few days early and my only award option to get to LAX is 50 minutes layover in NRT or I have to go through SFO which would give me an extra hour. Would prefer straight to LA though.
