I'm trying to use it but when I go through to IHG it said my earning preference (set for BAEC Avios) meant I wasn't eligible.
I then changed it back to IHG points but now when I go in it introduces me to Accelerate and a way to earn bonus IHG points - with no reference at all to 6,000 Avios.
And I was ready to change my hotel in Kiev the weekend after next!
