during a considerable amount of time on the 777 I am yet to be invited/rostered for a delivery flight
Hmm... get some time in son, lots of 777 veterans on that list in the office.
There are 7 deliveries scheduled before next summer, followed by another 12 in the period 2011-2013. Additionally CX has the purchase rights on a further 20 after 2014, so there should be lots of chances in the future.
Incidentally, there was also a list for the disposal flights for the 772's, when it looked like they were going to fly off to the desert.
I guess that the only guaranteed way to get your self a delivery (or disposal) flight would be to go into Management...
