So what do you all think of WT+? How does it compare with other p/e products you've used? I've used Virgin (old) and NZ p/e myself and, while better than economy (especially the Virgin product), I personally thought them poor value for money.

So, how does BA's current WT+ product stack up?

I ask because at some point, I will have enough miles to think about asking about upgrades on the day of travel (which I understand you can do, even when travelling discounted Y, if I'm understanding the sticky information correctly). This is possible but unlikely for me (would much rather save the miles for leisure travel, buy WT+ and upgrade to CW) but it might be a possibility from time to time.
