Reply To: The ‘How to book the return leg with 2-4-1 companion voucher’ thread

*Just re-reading your post, I’m now thinking this isn’t a T-355 booking, so you may struggle to get BA to add your inbound leg or refund 50% avios, in which case you will either have to stick with what you’ve got, or start from scratch and hope there’s availability.

Remember you can use the other half of each voucher on another trip, as long as it’s within 12 months of each flight. Read the full rules on this though before making any decisions!
