when does the tickets expire

Military Freedom pass expires on 31 Dec, 2021.

After purchasing an annual pass, we had a year to activate them from the date of purchase. After that initial trip, it started our one year.

We bought season passes. They expire Dec 31, 2021.

They do at some point, but the expiration depends on the kind of ticket. Usually somewhere on the ticket it says when it FULLY expires.

Tickets expire within a week.

Unused tickets usually don't expire.
