I believe that it is in LHR config (they didn't envisage MAN long-haul operations to begin with!). However, they have a bit of time to get it suitable for MAN ops.
In terms of loads, AC are expected to be using a mix of A330s and A340s at least twice a week from July to September (though this may be related to something or other happening near here, the name of which momentarily escapes me
). It also gives an indication that most of the traffic is VFR/tourist and not F/J class.
If bmi pick it up the AC route, it means we'll go back to daily year-round services (not sure if they'd route it via GLA though, as AC always did this in winter).
