Thankyou for your help. I have just looked over the threads and realised that each time the topic has been brought up you have patiently directed the person asking to the existing threads. Sorry! I shall have to become more FT savvy. I did notice, however, that posts on "firstclassflyer" go back as far as 2002, so they must be doing something right, or they would have gone out of business, dont you think? Mmmm. I remain unconvinced. Will get to know this site better first, I think, so I can stop asking repeated questions...Zzz
