I missed the bus or the bus did not arrive. Can I travel on the next bus?

Yes, you can travel on the next bus. Your e-ticket is valid from 15 minutes before the bus you booked is due to depart and remains valid for 30 minutes after the bus you booked is due to arrive. If you book a ride on a route served by several operators, your e-ticket is only valid on services operated by the company you booked with.
