Reply To: Companion voucher booking – anything else needed?

Won’t it have an 075- number if it’s an IB flight, even if booked via BA?
Anyway, there was a long thread recently on whether the email receipt was enough. At the risk of restarting an argument I would say that practically speaking it is enough to show things have worked; but since it takes so little effort to check your avios balance, cc statement, and MMB for a ticket number (if it isn’t in your email) it is sensible to do so.
