Just 2 quick questions which, having quickly scanned the prior posts, I have not found answers to:

1) In the Ts & Cs it states "The Gold Upgrade for Two is a single cabin class upgrade available on a single or return booking of up to 2 people made on the same reservation."
Does that mean
a) exactly as it sounds - that it is flexible enough to stretch to an upgrade for 2 people on both inbound and outbound legs of a journey
b) a bi-directional upgrade for 1 person or uni-directional upgrade for 2

2) Can the upgrade apply to multi-leg journeys would e.g. LIS-LHR-LAX booked into WTP (for the long haul and obviously Y for the short) all be upgraded to Club when the voucher is applied?

Thanks for an answer, my apologies if already covered!

Scratch that - I see there are multiple threads regarding GUF2s and that the answer to 1 is a) and to 2) is Yes!
