I have booked an OW Explorer ticket departing KIX, going like KIX-HKG-MAD-ORD-DEN-(Several USA points)-JFK-HND. I would like to know if the following changes are possible:
1. On the return, can I choose to go JFK-HKG, and then stopover, then HKG-KUL-HND? That is, can I go through HKG twice?
Yes. You are allowed to visit HKG twice. You are allowed up to two stopovers in your continent of origin. Both of them can be at the same place.
2. Within the USA, can I go through one airport multiple times? For example, after DEN, can I do DEN-DFW-BOS-DFW-JFK-HND?
Yes.
Thanks!
You're welcome
