NEW DELHI/PARIS: Indian regional airline Fly91 is close to placing an order for at least 20 turboprop ‌aircraft ⁠from ⁠Franco-Italian planemaker ATR as it looks to expand its fleet, three sources familiar with the matter said.The ​deal would be ⁠a significant ‌bet ​on ​India's growing regional aviation ⁠market, where the government has ​sought to bring dozens ​of smaller cities into the air network through a subsidised regional connectivity scheme, ‌but several regional carriers have struggled to ​build ​sustainable ⁠businesses.A spokesperson for ATR declined to comment. Fly91 did ​not immediately respond to a request for comment.
