Nick ...didn't realise you were in two locators...assume there must be a good reason. That makes it difficult for FD or NW. I don't know how easy or otherwise it is to somehow join the two together....and I imagine you booked on line and not through a travel agent....not sure what to suggest..you need a better brain than mine on this one. I suppose the priority is the segments over the pond....I've still, between you and me ! got a number of NW miles for use in my US account if you think that they may be useful to you.
