A quick answer to your second question (DUB-LDY): the
CAA November provisional stats show 2,213 passengers in November 2008 compared with 2,398 in November 2007 (down 7.7%). Not a huge change but certainly not a positive one (especially since the capacity has increased significantly IIRC). Perhaps part of the decline is due to poorer interlining arrangements through Dublin, i.e. easier to book through tickets on BA paper than on RE?
