All one-way and round-trip tickets are valid for 1 year from the date of purchase. The dates displayed are schedules for a rolling week in 7 day increments; they do not change and would be the same for each subsequent rolling 7 days. And while you may be prompted to select an anticipated date and time of travel when booking a bus ticket online it is for planning purposes only as all tickets are non-reservation.
Feel free to purchase your ticket at any time and travel at your leisure and be sure to check our daily schedules here for all bus routes along with our service advisories page (click here) within 7 days of your travel to ensure you have the most up to date information.
