But they can’t book the SYD-LHR flight as a one-way or even as the outbound part of a return as it is after the 2-4-1 expires so they’ll need to book an outbound flight to somewhere in order to book the SYD-LHR flight they want.

Edit. I think I may have misunderstood that the voucher will have expired before the dates they require.
