Doing some trip planning for our cruise out of Hong Kong next year. Hoping to fly first from Syd to HK and then J back from Singapore on points. I've worked out I can't book 2 classic award seats in F, will only let me do one, but he has enough points to do a booking for himself and I have enough to do a F seat for myself and 2 J class back, but I don't want to book one online and find I can't secure a second one, will the CC tell me how many are avail or does anyone here know how many seats are usually avail?
