OK, but where does one enter their Exec Club # on the John Lewis website? Just tried it (via the link from the BA website) and went down the path of trying to buy some Gift Vouchers and got to the final stage to enter my CC - but nowhere does it ask me for a BA EC#
How does one get these x4 BA Miles?
I realise you were just testing how the process works - but be aware that you will not get the BA miles for linking via the BA website if you buy gift vouchers. I assume they will however count towards your Amex spend no problem.
