I'm in London now and i'm really impressed about the powerful of an emerald card.
I'm BA gold card holder.
I bought 2 separate tickets
1) mil-lhr-jfk in economy on BA (Q class - which is the most discounted eco class on the route)
2) nyc-yvr in econmy on CX (in H)
MIL-LHR as expected
LHR-JFK --> upgraded to WT+
JFK-YVR as expected
YVR-JFK --> upgraded to C/J
JFK-LHR --> double-upgraded to C/J
I'm speechless...
thank you OW
