Do Gold Mission Pass tickets ever expire?

I just bought the ultimate bundle and i was wondering if the Gold ticket ever expires if i dont redeem it, because i want to use it next "season" because this one is mostly over already. Anyone know if they expire?

Considering that the Tickets stack in your Inventory if you have more than one, I would heavily assume they don't expire.

They shouldn't expire, since you can use them on any mission pass that is current.
