Bagso - ref your comment about pax usinmg the BOH-MAN flight to interline to long-haul destinations....
I think it would be a good idea, if you could do this, rather than driving to the hell-hole that is LHR, but as with most other LCC's (EZY/WW/FR etc...) you can not interline your baggage to/from other flights, or check-in from/to other flights, even with the same carrier. BE is an exception to this, as they are still in many ways a traditional carrier - codesharing with CO/AF etc.
