We purchased tickets at the airport kiosk and were offered the chance to purchase tickets for our return trip back to the airport as well. Unfortunately there was a mini marathon going on the day of our return ticket and the route we were on was out of service for the day. (Not good when you find out while standing at the bus stop and no bus comes.) There was no way we would have known this, but apparently Aircoach did and sold us the tickets anyway. When we requested a refund for the tickets we were unable to use we were told they couldn't honor that request because we should have looked at the website and noted the change in service for the day. Be sure to check schedules before booking your tickets.
