As far as I have heard, as the MYT A330 A/C go into be painted into TCX colours, they are also fitting the cabin out with leather seats and taking out seats to increase leg room to 33" then the TCX longhaul fleet follow on, it should all be completed by March 08.
Another rumor (nice for the crew) is that on the longhaul fleet crew rest areas are going to be fitted, not sure when tho'
