I've used the standard UK number 02036843774 to cancel an avios booking without too much difficulty, although it is a very slow process, with lots of spells of hold music. One thing I'd like to check though - I cancelled within 24 hours, but was still charged a cancellation fee (on a BA flight). Is this correct?
The agent said that avios bookings didn't get the free cancellation within 24 hours, but given that she didn't seem to sure about a lot of things I thought I'd check here.

Thanks
