The following is the availability on http://publicbackup.com/shared/flyertalk/availability/

for the flights I am on. The first set gives the availability for each segment when checked as stand alone segments.

BKK-NRT J9 C9 I0 Z0 Y3 B0 M0 H0 Q0 V0 L0 T0 K0
NRT-DTW J5 C6 I0 Z0 Y9 B5 M5 H3 Q3 V3 L3 T3 K0

The following is the availability for each segments when checked as a BKK-DTW flight
BKK-NRT J4 C0 I0 Z0 Y3 B3 M0 H0 Q0 V0 L0 T0 K0
NRT-DTW J4 C0 I0 Z0 Y5 B3 M0 H0 Q0 V0 L0 T0 K0

Is the difference due to married segments? Which is a better reflection of availability. The date is Sept 20th. I haven't got KVS tool so I don't know what KVS tool says. It's too early to hope for a bump but who knows.
