Well aware of all facets of the AWC operation & their enviable worldwide reputation built up over many many years based over a STN HQ.
What you write is not really necessary because you only rehearse facts all know!.
AWC could have turned down a summer deployment with this airframe if they really really chose to (they were stating they already had signed some contracts for it even before delivery & perhaps I shouldn't have written just ad hoc charters) but for numerous reasons mainly their own economics I suspect & perhaps of course keeping one of their major customers ie "the flag carrier" happy the deployment works & has mutual benefits for both parties in this instance.
The last remark on my previous just related to the fact that it is slightly ironic this particular frame was at one time operated by BA from Gatwick!="A funny old business".
