We're using AA miles to go Cathay Pacific JFK-HKG-BKK. Wanted to stop at HKG on the return but no stopovers outside the US are possible so we booked BKK-HKG on Avios and HKG-JFK on AA. Flight home is January 30th.

Have a trip to Palm Springs in May. Got AA to book me First Class EWR to LAX as a continuation of the HKG-JFK one way, making JFK a three+ month stayover! Never would have thought of it but for places like FT. Saved the two of us 50,000 miles!
