There's no availability for the MAD - LHR sector on 10th July.
You should be able to ring BA and tell them that you want to Upgrade Using Avios from WT+ to Club World. It should really be that simple.
Sorry I wasn’t clear. I’m currently booked on July 9th LGW-POS. Trying to change to July 11th to be able to upgrade. Having issues with the change.
