Megabus fares start from $1.00, with a booking fee of 50 cents. Megabus follows the yield management model typically used by airlines where the lowest fares are offered to those who book early or on less popular schedules (normally, only two seats are sold for $1.00 per schedule). Also mirroring the low cost airline model, locations of stops are on public streets or at park-and-ride lots in most cases, usually either outside railroad stations or transportation centres in major cities, or park-and-rides or on college campuses in other cities. Tickets must be purchased in advance via the megabus.com website or by telephone. Upon purchase, passengers are given a reservation number which they show the bus operator when they board. Tickets are normally not available from the bus operator.
