Reply To: Open Jaw using companion voucher way after outbound flight

Either. The example I cite is using an expiring 241 from the pandemic. Booked MAN-LHR-GIB outbound, for April 2022, then subsequently booked AGP-LHR-MAN to fly 10 months later. Called BA and they refunded the 50% avios for the inbound leg with no quibbles.

Just be aware that the inbound leg has to be unavailable (as in not yet released) when the outbound is booked to guarantee that BA will play ball on this, so bear this in mind when booking your return flight.
