I have booked two long haul flights using ba miles. I am reasonably happy with the date I managed to book for the outward leg but my preferred return leg would be late in october 2009.

to secure the outward leg booking I have opted for a return leg in september 2009. currently, the latest date possible to book the return leg is 7 october
2009.

effectively I am trying to book a return leg 12 months into the future.

I know that BA customer service operates from 0600 but at what time does the on-line availability of ba miles flights get updated daily?
