I too can't see bmi wanting to re-integrate bmibaby into the mainline or regional operations. The airline has spent years and a small fortune on entering the low-cost market, and considering that bmi is soon up for sale, the purchaser (most likely LH) is only going to be interested in LHR and the high-yielding regional business, not an airline who will shortly need an expensive fleet renewal and who operates predominantly low yielding routes from airports with big LCC competition. Also, bmibaby don't have a base at BFS, it's more of a focus city with flights from all bases. WW will probably be around for a while yet as a middle of the ground LCC, or will be sold off to fund longhaul and the new BMEDistan routes.
