New Delhi: Urvashi booked an IndiGo flight to Ho Chi Minh City from Kolkata for Sunday. With no updates from the airline on the flight in sight, and getting increasingly anxious about the status of her trip, the marketing professional has now booked a one-way layover Air Asia flight to Kuala Lumpur that has set her back by Rs 40,000.

A spate of flight cancellations by IndiGo, India’s largest airline, has caused a surge in airfares on international routes the airline flies, besides to local destinations. While the government on Saturday put upper limits on fares on domestic flights, international rates are unlikely to be affected by the direction. Since foreign travel often involves multiple legs, hotel bookings and formalities like visa and immigration checks, the impact is more pronounced on international travellers.

For people like Urvashi, it also means a long-planned holiday trip turning into a mess.

“I don’t know if my flight will get cancelled or not, and I don’t want to take a chance,” she said, asking not to reveal her full name.

IndiGo for the last two years has pressed on international expansion, with 30% of its 2,300 daily flights now on international routes. It plans to increase this to 40% by next year.
