BA don't have DOUBLE the crew at their overseas outstation handlers, yet manage far better than back at base. Shouldn't it be the other way round ?
At most stations they won’t have any “crew” - that’s the subcontractors job, which leads into how different departments at BA work, no doubt service level agreements, certainly silo budgeting and a thousand and one other things that ultimately often leads to T5 being an extremely frustrating place to operate into (not excusing any of it).
