Got a bit of a pickle. In November 2021, I used CX miles that were set to expire in January 2022 for a partner award on JAL to Japan. It looks to me that Japan will not open to individual tourism by my departure date of August 31 (although there still is time for me to be proved wrong). This raises some questions:

1. Will I be able to convince CX to cancel my award trip and return my miles to my account with no penalty, based on the unavailability of a tourist visa to my destination? (I have no status with CX or OW.)
2. If I am successful, will CX return my miles to me with a new expiration date, beyond their previous January 2022 expiration?
3. What's the best way/phone number/office to call CX for answers to these questions?

Anyone have any experience to share on these questions? Thanks!
