Another exEU question relating to the Lloyds voucher.
I want to go say DUB-LHR-LAX in biz. That would mean booking WTP and then getting the voucher applied, assuming biz is available on award.
However, how does that work in practice, as WTP doesn't exist on the DUB-LHR leg ? Do you just book the award with economy on the domestic, and once the voucher is applied, both sectors get upgraded to biz ?
