Belavia Belarusian Airlines will retire its Tupolev Tu-154 aircraft on Dec. 28. The Minsk-based carrier’s fleet includes three of the type—one Tu-154 is already out of service and two operate charter flights between cities in Belarus and Western Siberia in Russia for oil and gas industry, ATWonline reported.

The carrier’s fleet also comprises two Embraer E175s, two E195s, four Bombardier CRJ100/200LRs, nine Boeing 737-300s, six 737-500s and three 737-800s, which were ordered in 2014.

In August Belavia announced it was rebranding and changing its business model as it took delivery of a new 737-800.
