I'm off to YVR on Sunday in WT+ so entitled to 2 x 32Kg (as an Au). I'm going to need three pieces (too many Xmas presents) so am vacillating between prebooking the extra piece and doing it at the airport.The flight is showing F0 A0 J2 C2 D1 R1 I1 W0 E0 T0 Y0 B0 H0 K0 M0 L0 V0 S0 N0 Q0 O0 G0 which to me says "lock down on sales as oversold in lower cabins". So in the glorious event of an opup would I be entitled to three pieces of baggage?
