¹ Total operating expense for all operations and service (in millions).

² Scheduled all-cargo operations expense.

³ Total scheduled-service cargo revenue, less scheduled all-cargo operations revenue, carried as a by-product in aircraft belly compartments. Includes freight, express, priority and non-priority U.S. mail, and excess baggage.

⁴ Total non-scheduled revenues times 0.95, assuming charter operations would only be conducted at a profit.

⁵ Total transport-related expense, less any excess of expense over total transport-related revenues.

⁶ We here project costs from April 1, 1979 (the midpoint of the data year ended September 1979) to April 1, 1980 the resultant increase factor effective through April 30, 1980.

⁷ Operating expense per ASM for year-ended September, 1979, times projected change.

⁸ Projected operating expense per ASM on April 1, 1980 divided by the operating expense as at July 1, 1977.

⁹ Adjustment results in a 2.5 percent increase in level over current January 1, 1980 factor.

¹⁰ Additional rental expense that would have been incurred had leases not been capitalized under FASB-13, less actual amortization of capitalized lease expense.

¹¹ Total fuel cost, scheduled service, times complement of rate of All-Cargo expense to total Operating Expense.

¹² Order 77-7-26.

¹³ Year ended March, 1977 cost per ASM, times cost escalation factor of 1.04543 (to July 5, 1977). See DPFI workpapers, Y.E. March, 1977.

¹⁴ Estimated average cost per gallon for the trunk plus local service carriers at April 1, 1980, divided by the average for the year ended September, 1979 (48.33¢).

¹⁵ Change in Trunks plus Locals cost per ASM as at April 1, 1980, to year ended September, 1979 times total Psgr/Cargo cost for the year ended September, 1979.

¹⁶ Includes Alaskan, Hawaiian and other regional carriers.
