I agree, I don't think any of them are particularly enticing for an prospective owner. My feeling is that there may be an opportunity for either WW or Regional to work with the bearded one to utilise the LHR slots. I agree that it does not fit in with BA's stated model, but it is possible that this may have changed slightly as part of the overall IAG group.
Indeed, it is probably just as easy for VS to wet-lease some narrow bodies from somewhere, but IAG does seem to be throwing down the gauntlet in the media today.
