In 1983, the first terminal stopped operating due to the opening of a new one. From September to October 1983, the airport was accepting transit flights from and to Chita, due to its closing, because of the runway re-construction. In 1988 and 1989, the airport started to serve a number of transit flights, including the international (Moscow – Pyongyang, including Air Koryo; Moscow – Ulan-Bator), shifted from Irkutsk, due to runway re-construction. That situation led to a huge optimization of the airport, where every day the airport accepted 70 flights, which 30 of them were served by Tupolev Tu-154. In 1990, the airport transferred 800,000 passengers in a year.

### 1991–2006
