Not sure that I "very conveniently sidestepped" anything.
I don't work for Virgin and have no reason to defend them. You're quite right that they had to show they were using the MAN slots before being able to apply for the other remedy slots (as a result, Aer Lingus (the former lessee of the slots) is facing some LHR schedule adjustments next summer).
FWIW, I am not at all convinced by the economics of the MAN service either - indeed, I'm not particularly convinced by EDI or ABZ, for that matter, but I see the play as being more of a long-term one: hang in there for three years and if it's not working, then switch the slots to other short-haul.
Is that a smart move? Well, let's say it seems a bit smarter now that DL with its deep pockets owns 49%, and will likely seem a bit smarter still if/when AF/KL takes a stake somewhere down the road.
Where do I see Virgin "rushing to serve", in your words? 3 daily NCE would be overkill and would lose them money (even if it earns them your respect
) But in a year or two I could imagine them using the slots for (for example) a VS/AF service to CDG, freeing up some of AF's LHR slots to enable some more Delta transatlantic services (with a bit of timing juggling, just as AF and KL made space in LHR for DL and their then-partner CO when OpenSkies came about).
I think AF/KL will come into this picture in a year or two (Delta's CEO used the word "accretive" in today's press conference when asked about this, i.e. AFKL and AZ can be added on to the bilateral DL/VS joint venture) and at that point the slot puzzle becomes easier to solve.
I understand that in your view it makes no business sense for VS to have incurred losses to be able to acquire slots, and then not to take up all the slots. I can question various aspects of VS strategy, but if they figured that the least loss-making thing they could do with those last 3 slots would lose them more than they'd ever get back in the future, I can't necessarily fault them for that specific decision
