DTW has NGO/MNL thru flt # 0629 on JUN 10, 11, 13.
10th and 13th are wide open--short lists
JFK is thru flight # 0173
and lists vary from very short to NRT to just med on the second leg to MNL--lots of seats coach
from what I've know, both are reboard at NRT

Other options are NRT from west coast but 2 flight numbers.
does that make a difference for USAir passes?
