if I make a booking with my PC number (which I think I may have to in order to use a discount code), is it possible to reassign the booking to my BAEC number after - I'm silver there so want to get the seat selection benefits for the 4 of us on the booking.

I've heard that PC numbers tend to be a bit 'sticky' after booking so just hoping it's not a case of choosing between the discount and the status benefits...
