"As Vistara accelerates its growth and prepares to take the next leap in its journey of becoming a global brand, certain changes have been introduced in the leadership structure.
"Strategy and Commercial are cornerstones of any airline's business, and these two areas will be bolstered to ensure focus on key priorities," an airline spokesperson told PTI.
The domestic carrier is preparing to start overseas flights and has also placed orders for a significant number of planes.
Vistara, which has 22 aircraft on its fleet, operates around 140 flights every day. The airline commenced commercial operations on January 9, 2015.
