Wardair withdrew as BHX no longer suited their new business model, which foolishly for them meant they went almost bust and were bought for pennies by Canadian. Max Ward made his name with very reliable, super punctual long haul heavy routes on p2p then blew it all flying A310s on the Candian domestic scene. They turned their nose up at PIK despite having operated very succesfully with B747s and DC10s for year, and demanded GLA access for business traveller friendly facilities or they'd not be back.
That worked out well.
With Rouge choosing MAN and Mainline having a large LHR presence, I think BHX is marginalised between the two yet again sadly.
