Well, with time running out I have taken the plunge and applied on behalf of my wife. Let's see if they have sorted their systems out by now.
3 months would run to June 15th which would take in the Jubilee holiday weekend as well, should we get away for that. I need to target at least 250,000 Avios, I think! Very annoyed that I had to already pay a 40% deposit for our Barbados trip in early May!
If you are BA Gold, it is worth looking at exisiting redemption bookings made on other credit cards to see if you could cancel and rebook (ensure availability is still there first!), moving the taxes to the Lloyds card. However, double check the fuel surcharge first as it could have increased since your original booking.
