The U.S. Justice Department announced on Tuesday that British Airways and Iberia Airlines agreed to pay $5.8 million to settle allegations that it falsely reported delivery times of U.S. mail being delivered internationally.

The U.S. Postal Service contracted with the two airlines to take mail to six locations in the U.S. and to various Department of Defense and State Department locations outside of the U.S. In order to be paid for their services, the airlines were required to submit electronic scans to the postal service to show the mail was delivered to specific locations. The settlement on Tuesday resolves the allegations that the airlines falsely reported the time the airlines transferred possession of the mail. They admitted no liability, however.
