Hi y'all. This is my first post, so thanks firstly for the amazing forum, which helps to educate newbies to experts. I think I should be ok, but wanted to have a sanity check on this nested ticket since there seems to be a lot of uncertainty around them.

I'm looking at arranging the following itinerary:

[A trip] Dec. 15 RDU --> ORD (RT award ticket on AA)
[B trip] Dec. 16 ORD --> HKG (on JAL through NRT)
[B trip] Jan. 6 HKG --> ORD (JAL again through NRT)
[A trip] Jan. 6 ORD --> RDU (return on the AA award)

Tickets this year to Asia seems to be really high so this would make things cheaper for me, since my AA points will expire soon anyway. I realize that (a) I'm probably good with any minimum stays on these routes... and are there still minimum stays now anyway? and (b) these would be conducted using two different airline tickets, but since JAL and AA are both Oneworld, I'm just doing a huge sanity check for my paranoia before I go ahead and book this all. Really appreciate your input.

Thanks!
