In late 1991 two firms, Delta Airlines and the TRump shuttle, provided air shuttle service between New York and Boston of Washington. The one-way price charged by both firms was $142 on weekdays and $92 on weekends, with lower off-peak advance purchase fares. In September 1991 delta increased the per trip shuttle mileage given to member of the delta frequent-flier program from 1,000 to 2,000 miles, even though actual mileage from New York to either Boston of Washington is about 200 miles. Moreover, delta also offered an extra 1,000 miles to frequent fliers who made a round trip on the same day, raising a possible day's total to 5,000 miles. Almost simultaneously, Trump changed the frequent-flier mileage it gave to shuttle passengers. (It participated in the One Pass frequent-flier program with Continental Airlines and some foreign carriers.) What sorts of changes do you think Trump made? Why?
