Just tried to book my latest flights and BA.com has introduced a requirement for the Amex Safekey additional security. As this is the first time I've come across this and I want to use my BA Amex I followed the instructions to set up and register the card, but I can't see an option to complete the registration once all the details are entered. The only options appear to be to pay with a different card or with Paypal.

Anyone else seen this issue or am I missing something blindingly obvious???
