Each ticket may have an expiration date, and these may vary across routes and ticket types. On each Search Tab (One-Way, Round-Trip, Multi-Ride) There is a link that lists the fare rules for that ticket segment including the expiration date. If you set up an account, each of your tickets will be listed on your accounts page in your "My Tickets" section. We will list the expiration date of each ticket next to it, so you can reference them with your account at any time. For multi-ride tickets, we will also show how many rides you have remaining on your ticket.
