Airport Coach Service Company operates scheduled coach service from Bostons Logan Airport to downtown Boston and to Cambridge. A common scheduling service center at the airport is responsible for ticketing and customer service for both routes. The service center is regularly staged to service traffic of 2,400 passengers per week: two-thirds for downtown Boston passengers and the balance for Cambridge passengers. The cost to operate this service center is $7,200 per week normally, but is higher during weeks when additional help is required to service higher traffic levels. The service center costs and number of passengers serviced during the weeks of August follow:
