If we are just talking about the wet lease that's not particularly fascinating news (except that EI has reasonably low costs so probably a good choice). If it were a case of an actual partnership, with VS and EI joining forces, maybe with the backing of EY, then we could be off to something interesting as it would give the new 'block' a decent size and some degrees of freedom to organise an intelligent network. Crew gossip can be hit and miss though so I'd rather wait for some more tangible elements
