If possible can some one give me some clarification, as I'm getting mixed messages.
I am one trip away from earning a GUF2 voucher.
I have a CW reward booking in December, GLA > HND, using an Amex companion voucher.
If there are 2 A class seats still available in First, by the time I get my voucher, can I use the voucher to upgrade the 2 CW flights to First? Understand there’s potentially a few more avios to spend on the upgrade.
