Reply To: Using Amex companion voucher to OneWorld (not BA) destination

[NorthernLass]

Only the BA part, as a separate booking. The articles and threads on here will tell you everything you need to know about the voucher, including that it can only be used on BA, IB and EI, so you are limited to their routes.

Redemptions to HKG on BA are about to get more difficult as well!
