An open ticket is NOT VALID until you activate it.
How to activate? You can simply log in your GotoBus account and select a new date for your travel to have a new e-Ticket. Or, if you don’t have a GotoBus account yet, please create an account with the same contact email address, and log in to select a new date for your travel to have a new e-Ticket.
Open tickets may be subject to extra charges if there is an increase in price. Open tickets must be used within 365 days, with the same travel provider, and on the same route going the same direction.
