U.S.-based cargo airline 7 Air has obtained its FAA Part 121 Air Operator Certificate and conducted its first test flight with a Boeing 737-800F from Miami to Dallas in January. Operations are expected to begin next week. The airline operates two Boeing 737-800Fs, with one currently active and the other parked. The active aircraft, a former Jet Airways plane, has recently been converted to a freighter. 7 Air offers various services, including ACMI, CMI, and charter options, and must adhere to FAA regulations regarding hazardous materials for air transport.
