FWIW, I think my U came through, woohoo!
My itinerary said I've got it, but the points haven't came off my statement yet.
I've printed a copy of my initerary out in case anything happens at check-in...
Anyway, this is the latest AMEX-ITN information:
F4 A4 J8 D9 U0 Y6 B0 H4 K0 M4 L3 S3 V3 O2
It's a bit strange how the numbers vary compared to last week...? What're the other classes like L, S, V and O...?
