Recent threads indicate BA's policy is now not to do this for you either since it's a separate ticket and non-oneworld carrier anyway. Although you have a long connection time, I think as the first carrier they're still liable for any mis-connects (which is very costly) so they won't risk it.

Edit: Here's one thread (with links in it it others): http://www.flyertalk.com/forums/show...nterline+rules
