IndiGo and Air India have warned passengers of service disruptions following Pakistan closing its airspace to Indian airlines as part of its measures against Delhi's response to the Pahalgam terror attack.

IndiGo said about 50 international routes may be adjusted slightly. It also said it was cancelling flights to Almaty from April 27 until at least May 7 and to Tashkent from April 28 until May 7. Indian airlines’ expansion plans have already been complicated by delivery delays from Boeing and Airbus.
