The MC-21, SJ-100, and Tu-214 could be supported by a new levy on air passengers. The funds could be directed towards preferential leasing of domestic airliners and compensating airlines for part of their increased expenses in the first years of operation. The initiative is being developed by the Ministry of Transport, the Ministry of Industry and Trade, and Rostec, but no final decisions have been made yet.

According to Kommersant, the main option currently could be a payment of up to 500 rubles for a domestic flight ticket and up to 1000 rubles for an international flight. One of the publication's sources suggests higher rates — up to 700 and 2000 rubles, respectively. With a passenger traffic forecast for 2025, this would provide from 68.1 to 84.4 billion rubles annually, depending on the chosen levy size.

It is assumed that the Ministry of Transport could become the payment operator. Part of the funds is intended to be transferred to leasing companies to cover the difference between the cost of Russian aircraft and the preferential price at which carriers receive the machines. Another part may be directed directly to airlines, including to compensate for increased aviation fuel costs at the beginning of operation of new types of aircraft.

Kommersant's sources link the need for additional support to the high cost of the first series of Russian airliners. According to Kommersant, the cost of the first MC-21s is estimated at 8.9–11 billion rubles, while the cost of Airbus A320-200 and Boeing 737-800 until 2022 was about 3.4–4 billion rubles.

For the SJ-100, the estimated cost is 5.4 billion rubles, compared to approximately 3 billion rubles for the Embraer E190. At the same time, after the cessation of regular supplies of Western aircraft to Russia, their acquisition through intermediaries also becomes more expensive.
