What do we know about Saratov Airlines?
Saratov Airlines is based in Saratov, 840km south-east of Moscow.
In 2015 it was banned from operating international flights when surprise inspectors found someone other than the flight crew was in the cockpit.
The airline appealed against the ban and changed its policy before resuming international charter flights in 2016.
It flies mainly between Russian cities but also has destinations in Armenia and Georgia.
