The Bulgarian Cargo Air, which specializes in cargo flights under wet lease agreements, will be expanding its fleet in the near future. A 23-year-old Boeing 737-400, which has so far been flying on an ad hoc passenger charter, is currently being converted into a freighter by Aeronautical Engineers Inc. in Dothan, Alabama / USA and will soon return to Europe. In addition to the eighth Boeing 737 Classic, Cargo Air is also about to integrate a first Boeing 737-800BCF. Its takeover was recently delayed due to the flight ban for the Boeing 737 MAX, but the corona pandemic made inexpensive second-hand Boeing 737-800s available on the market again. A Boeing 737-800 winglets from former stocks of the Danish Primera Air or, most recently, Travel Service Airlines, which have been parked in Lourdes, will soon be equipped with a cargo kit at AEI. With 11 AAA standard containers and an AKE position, the Boeing 737-800BCF can accommodate an additional loading unit than the Boeing 737-400F. According to information from the airline, a second Boeing 737-800BCF will join the fleet in the coming year.

Cargo Air has been using two Boeing 2007-737SF and seven Boeing 300-737SF since 400 mainly for DHL in their route network. A B737, however, operates as a link between Romania and the international UPS network on the Cluj-Cologne / Bonn route. In Austria, Cargo Air has been operating the DHL freight route Belgrade-Linz-Brussels four times a week for several years.
