yeah -- so there's the white part (stub) and the blue part (counterpart to stub? )

white will show: BA/<number>
blue part: <OW tier>/BA/<number>

if you're VIP or FIRST or whatever, the white and blue parts usually say the same thing. That isn't always the case, though: I just got off a flight where the white part said VIP and the blue part said "DEPARTS TERMINAL 1"
