Hello Joan
That is interesting what you say about your Travel Insurance through the bank. I have a Gold Account with Lloyds TSB and they do not issue a policy number as such. They use your bank account number, including the sort code, as the policy number.
I phoned AXA , as the insurance is done through them, to find out if I was covered for CHINA, and they told me that they don't need to know where and when I am going anywhere, as long as it is for no more than 30 days at a time.
