In early 1999, AeroLitoral was operating 29 Fairchild Metros and 6 Saab 340Bs. One Fairchild Metro XA-RYY had been converted to freighter and operations to Mexico City were resumed on behalf of Aeromexpress. In August 1999 a new CEO was appointed and Raúl Sáenz Campos replaced Carlos Treviño Treviño after a long time being at the airline. On December of the same year, the directive board decided to start a fleet renewal process, by replacing the first 3 Fairchild Metros .
