Deferring to the experts here, as I have access but no idea what it could mean:
US POS
BA 182 0 JFK
06/30/17 10:55 PM LHR
07/01/17 11:00 AM 744
F
73% / 22m F7 A3 J4 C0 D0 R0 I0 W1 E0 T0 Y4 B0 H0 K0 M0 L0 V0 S0 N0 Q0 O0 G0
This looks pretty full in the back, is there chance of being op upped from W to J in this scenario?
