TBH I can’t be bothered doing any faffing around with the Barclays voucher. I either use it somewhere where both legs are available or use it for 2 pax outbound and make other arrangements for the inbound.

I can’t blame you for doing that, also for peak long-haul flights you end up paying more Avios for using these vouchers instead of the Amex one.
