Yes. Technically, no voluntary changes are allowed to Airpass tickets. I’ve only been able to have hem changed in the event of IROPS or if I’m doing a same day flight change (they just revalidate the ticket if you meet the criteria for SDFC, including same
routing, etc.).

So, you cancel and rebook… just be prepared for a slight delay getting refunds back to your Airpass account balance. It generally takes at least 24 hours, sometimes can take several days, and occasionally, the refund just never processes.

You (or your company) will have to do your own accounting to ensure you aren’t missing funds from tickets that were never refunded.
