Not sure if I should jump in here, or go back to my own thread, but:

Is it possible to do something like US- Africa - US - Asia - US - Australia on one of these awards, as long as I manage the cities properly and keep the segments below 16?

Assuming that is true, how do the dates work? I would obviously be looking to extend it to as close to twelve months as possible, but the flights farther out may will not be open when I book. For example, I would need to call say 4 months ahead of time to get the US - Africa - US portion, but would want to fly to Australia 15 months down the road. Do I book it for nine months out and then change the dates, or am I only allowed to fly one year after the booking date?

Finally, are co-terminals treated as one city for purposes of stopovers and connections? Thanks!
