Any routing MAN-xyz is meant to me more expensive than MAN-LHR-xyz, that's the crazy world of airline revenue management. It's not a LHR/MAN thing more a global spoke to hub behaviour.
What do you mean by that Skip? I genuinely do not understand why it's "meant to" be more expensive.
I can see why the operating costs 'may' be more expensive than at a main base. crew accomadation etc. But 'meant'?
