Seasonal expansion and contraction continued, but with year-round service to all locations. The larger aircraft were flown in New England during the busy summer months, with the smaller aircraft operating in Florida. In the winter months, the fleet would be swapped, with the DC-3s and Martin 404s migrating to Florida, and the Cessnas flying in the north. PBA also operated a flexible, demand-based schedule with its different fleet types, even in peak season. On days when demand was higher, the larger aircraft would be operated, but if bookings were light, the smaller aircraft would be used to save on fuel and operating expenses.
