Strelnikov,
Piers6 was referring to Companies which have located their UK Corporate Headquarters in the Corridor running out Southwest from Heathrow such as Woking, Guildford, Basingstoke etc. with a view to good connections with Europe and beyond (but also originally with the important business centres of the UK). These locations are far easier to reach from Leeds using the LHR flight than via Kings Cross then accross London to Waterloo or Victoria and onwards. My own company has it's UK Head Office in Guildford with Training Facilities in Horsley Surrey. When I've used the "old" BM early morning departure from Leeds I could be working at a desk in Guildford by 0830, and also had quite a decent little breakfast en-route.
Bmi have been working away to trash the LBA-LHR route for years now. It would be great if BA could be persuaded to return, but highly unlikely. Dept of Transport should have stepped in to ring-fence slots for regional services.
