CATC passengers share the trip. Direct trips are not available. CATC will pickup and drop off passengers as it travels across town. This is taken into account when dispatch takes a reservation and schedules a pickup time. And the 15 minute window gives drivers some flexibility in meeting passenger needs.
So, sit back and relax. If dispatch was informed, the driver is aware of your needs. They will do their best to get you to your destination on time.
It is very difficult and often impossible to change a destination later than 3:00 pm the day before CATC arrives.
Never attempt to change a destination after boarding. That bus might not be scheduled anywhere near a desired change in destination. Call the dispatcher to request the change of destionation at least one hour in advance. Remember The Bus is available with no reservation required!
