I hear a move from the LH/BD Amadeus IT plafform to a US low cost airline hosting platform work in progress. Hopefully this retains the functionality business travellers need
Since when did BD's IT platform
ever work properly? It was a running joke amongst frequent flyers for years!!
I've experienced it from both sides of the desk (i.e. as staff and fairly regular passenger). The website looked pretty but was in many ways pretty useless and airport computer systems were constantly crashing. I can remember several occasions where the entire res/check-in/dispatch system fell over and the whole network was being managed manually with handwritten pax lists and load sheets being faxed all over the place... Not good.
Always thought it was odd when the whole thing was based on a LH system, which you'd expect to be fairly top-notch.
However a move to a low cost system doesn't sound promising; esp regarding the codesharing/interlining issues you mentioned.
