After IndiGo raised fuel charges, the Air India group on Tuesday announced a fresh hike in fuel surcharge on domestic and international flights, signalling a broader rise in airfares amid a sharp spike in Aviation Turbine Fuel (ATF) prices.The latest development comes as global jet fuel prices continue to surge, increasing cost pressure on airlines and pushing ticket prices higher across routes. According to the International Air Transport Association, jet fuel rates have nearly doubled in a month, making it one of the steepest increases in recent years.For domestic flights, Air India said it will introduce a distance-based fuel surcharge from April 8, replacing the earlier flat rate. This follows a decision by the Ministry of Petroleum and Natural Gas and the Ministry of Civil Aviation to cap the impact of ATF price hikes at 25 per cent, offering limited relief to domestic flyers.Under the revised structure, passengers will pay Rs 299 for flights up to 500 km, Rs 399 for 501-1,000 km, Rs 549 for 1,001-1,500 km, Rs 749 for 1,501-2,000 km, and Rs 899 for routes above 2,000 km per sector. The revised charges will also apply to Air India Express services.On international routes, where there is no government cap on ATF prices, the airline has announced a steeper increase in fuel surcharge. Air India said global jet fuel prices rose to USD 195.19 per barrel by late March, compared to USD 99.40 at the end of February, reflecting a near 100% surge.Passengers flying to West Asia will now pay USD 50 as fuel surcharge, while those travelling to Southeast Asia will be charged USD 100 and Singapore USD 60. Africa routes will see a surcharge of USD 130.For long-haul travel, the impact is sharper. Flights to Europe, including the United Kingdom, will attract USD 205 per sector, while North America and Australia routes will see a surcharge of USD 280 from April 10.Air India said the revised fuel surcharge does not fully cover the rise in ATF costs and that the airline continues to absorb part of the burden to avoid a sharper increase in ticket prices.Tickets issued before the effective dates will not be impacted unless passengers make changes requiring fare recalculation.With both IndiGo and Air India revising fuel charges within days, airfares are expected to rise across domestic and international routes. The spike in ATF prices, a key driver of airline costs, is likely to keep ticket prices elevated in the coming weeks, especially during the peak summer travel season.
