Want to buy a ticket for the 3:15 bus out of Logan at 3:16? You can't...even when the bus is 30 minutes late. Some drivers can sell tickets for cash...some can't/won't. Have a reservation ticket for a specific bus and it's full? Tough luck. Want to just look at a schedule for trip planning... don't bother pressing on the PB.com "Full Schedule"...you get dumped into the "Purchase Ticket" page. Let's not even get into their reliability.
