I recently booked what I thought was a really good WT+ Fare with Car hire to DEN for my Christmas Skiing Holiday on the BA website. I was fully expecting to have to pay for an extra driver however, I have now seen on the BA car rental page that being an BAEC member entitles you to a free additional driver. I joined the Exec club after making the booking and have made sure my BAEC number is now linked to my booking. So my question is will my car hire booking now be eligible and if so do I need to have this added to my car rental voucher by BA.

I have tried a search but not managed to answer my question so any advice would be grateful before I try to contact BA.
