As I said in another thread, I actually think an IAG takeover of Aer Lingus would be good for those not travelling from the LHR catchment area. It will as Alex says be good for those travelling west and will give BA an excellent springboard to allow not only flights from the regions in to the USA via Dublin but also from LHR as they will have the pre-clearance at Dublin. As I live in SW London it will probably not effect me a great deal (although the pre clearance may make it attractive if connections are good like LCY/Shannon) but from Birmingham, Manchester, Glasgow, Edinburgh and a few other places BA will be able to offer an excellent service with decent returns. Makes IAG a buy in my view. Wonder if they will keep the Aer Lingus brand???
