IndiGo raises fuel surcharges as aviation costs climb.

IndiGo said higher fuel charges would apply from 6 October after Indian aviation-turbine-fuel prices rose about 14% month on month. Domestic charges increased to 375–1,300 rupees from 275–950 rupees, while the international range became 1,000–10,000 rupees.

Reuters noted that fuel can represent as much as 40% of an Indian airline's operating costs. IndiGo reported a 3.82 billion-rupee loss in its first quarter, illustrating how quickly energy costs can pressure otherwise strong passenger demand.
