Air India and IndiGo plan to cut domestic flights from today, June 1, for 3 months due to rising ATF prices and weak post-holiday demand. Air India will reduce up to 15% of flights and IndiGo 5-7%. Key routes like Mumbai-Ahmedabad and Delhi-Bengaluru are affected. ATF costs have crossed ₹1 lakh per kiloliter, impacting airline profitability significantly.
