47.403-3 Disallowance of expenditures.

      (a) Agencies shall disallow expenditures for U.S. Government-financed commercial international air transportation on foreign-flag air carriers unless there is attached to the appropriate voucher a memorandum adequately explaining why service by U.S.-flag air carriers was not available, or why it was necessary to use foreign-flag air carriers.

      (b) When the travel is by indirect route or the traveler otherwise fails to use available U.S.-flag air carrier service, the amount to be disallowed against the traveler is based on the loss of revenues suffered by U.S.-flag air carriers as determined under the following formula, which is prescribed and more fully explained in 56 Comp. Gen. 209 (1977):
