In 1928, Hungarian Aviation aircraft had already flown some 850,000 km, carrying almost 10,000 passengers and a payload of 1 million kg.
In the 1930s Malert opened and gradually expanded domestic flights, while aviation agreements signed with foreign states meant that the Ju-52 and SM-75 aircraft were able to bring the major cities of Europe closer to Budapest.
Its aircraft were requisitioned and Malert employees drafted for military service; by the end of 1944 the company's air fleet had been totally destroyed, and the airports in Hungary were in ruins.
