i know what i know and for clarification some of this is undecided, some is discussion and some is a product of knowledge cumulation.
the 787 is being discussed but is highly likely as the new longhaul aircraft for tfly due to it's options and efficiency, it is likely to fit into the fleet best, the sister companies have been under discussion for a long period in tui's amalgamation in a/c leasing etc. Aircraft fleeting accross companies is the direction that tui want. eg corsairfly's 747's are currently operating at 80% loads and would be better on the haj with 767's that tfly have on lease operating their flights. A true mixed model accross tui is well under dilligence. the 787 order will only be made once the market is more secure. united is under what we would call administration and is highly likely to fold under market forces and this has been expected (one of the american carriers) to happen for a while and untaken options could be many and extremely cheap because of boeing and airbus operating procedures.
klm engineers have been running much of the 737 engineering and have all been offered postions in house, and are currently thrashing something out which is mutually beneficial. this is likely to be based at dsa due to other plans, available space and possible planned fleet expansion.
a satelite facility at dsa is not planned but is at higher stages of discussion, space is being offered at a superb price both airside and within grounds, ema is shorter lease and higher price, dsa would be a long term descision which has not yet been made but is extremely viable for 737 fleet at least due to fleet differnces and development in the future
dsa sales are exceeding predictions as charter flights have been increased and low cost reduced but sales are performing well. long haul charter is surpassing best predictions excluding cun which is on par.
dsa is at present central operational focus for the future for a base which could be huge.
