Why you ask? Because I have no status in either airline and one simple word, "Avios". A merger makes those 4500(9000) Avios trips much more accessible to me. We are planning a move in the future to near where my family lives and that means leaving my in-laws in this area. Having availability to use the small amounts of Avios for RT's makes the prospect of leaving her family much easier for my wife. Sure beats the 25k or even the discounted RT's offered by the legacies.
