Like tired, I'm not convinced either that the Classic will be retained after April, or that we are likely to see new (or restored) routes this summer. Loads on most routes are very good now, and yields are improving, but not to the point where an increase in costs and risk is likely to be entertained - yet. The likely need to recruit cabin crew this spring is, I'm sure, more to do with the very large cabin crew turnover the airline has experienced (as far as I am aware, there have been very few redundancies necessary in cabin crew - so many leave in the normal course of things), than any envisaged expansion - or admission of undermanning.
As for the problems now stored up for the future by the speed and brutality of the redundancy, I suspect that, unless the overall market improves substantially, not many of those who talk about it will actually leave, and few of those asked back could afford to refuse. In the prosperous years hopefully to come thereafter, however, who knows....
