In 1992, MIAT bought five Chinese Harbin Y-12 commuter aircraft and acquired a Boeing 727-200 from Korean Air, one more following in 1994. An Airbus A310 was leased in 1998, and a new Boeing 737 was leased in 2002 to replace the aging 727-200 fleet. Between 2003 and 2008, MIAT's An-24 and An-26 fleet was gradually retired. In April 2008, MIAT received its second Boeing 737-800 aircraft on lease from CIT Aerospace. In July 2008, MIAT ended scheduled domestic flights completely. In June 2009, the airline temporarily resumed scheduled domestic flights to Mörön and Khovd using its Boeing 737-800 aircraft.
