What baby are doing is throwing absolutely everything they can think of at the market as early as possible and hoping there is enough business out there to make a case. Make no mistake this has been done to try and stave off LH and the bmi board. If it works it will have to be flown with 17 aircraft there will be no more unless forward bookings are phenominal (which they aren't). If it fails it will have to be flown with 13 aircraft (4 leases running out and we know what happened last time) or perhaps none !
The deal with TCX is clever. If baby have written the contract well they will have given TCX a massive payout if the obligations can not be met, hopefully more than the savings to LH by getting rid of 4 more aircraft ! However, if they bite the bullet and just decide to shut it down that all becomes irrelavent.
Baby sees itself less dead in the water more in a holding pattern running the QRH hoping to stay alive until they can work out how to !
