InterGlobe Aviation 's IndiGo has announced a comprehensive revision of fuel charges across its domestic and international network, responding to unprecedented increases in Aviation Turbine Fuel (ATF) costs. The new fuel charges will apply to all bookings made after 0001 hrs on April 2, 2026, marking a significant adjustment to the airline's pricing structure.

Dramatic Fuel Price Surge Triggers Revision

According to IATA's Jet Fuel Monitor, fuel prices for the region have increased by over 130% on a month-on-month comparison. This substantial surge has forced the airline to recalibrate its fuel charge structure to manage the impact on operating costs. The airline emphasized that the measure has been driven by a sudden and substantial change in the operating environment.

Government Intervention Limits Domestic Impact

In a move to support air travelers and the aviation industry, the Ministry of Petroleum & Natural Gas (MoPNG) and Ministry of Civil Aviation (MoCA) have decided to pass only a partial and staggered increase of 25% to airlines for domestic operations. This government intervention has enabled IndiGo to implement a more moderate fuel charge increase for domestic routes compared to what would have been required to fully offset the fuel price surge.

Distance-Based Domestic Fuel Charges

IndiGo has recalibrated its domestic fuel charge structure to vary by different travel distances. The revised charges create a tiered system based on route length:

Substantial International Route Adjustments

For international operations, ATF prices have more than doubled in the last month, driving a significant impact on operating costs. The international fuel charges vary considerably by region and distance:

Measured Response to Cost Pressures

Despite the substantial fuel price increases, IndiGo has chosen to pass on a relatively smaller amount to customers, keeping in mind the consequential burden on travelers. The airline noted that fully offsetting the fuel price increase would require substantial fare revisions beyond the current fuel charge adjustments. IndiGo expressed gratitude to the government for timely intervention, stating that without this support, the April 2026 fuel cost increases would have severely impacted the affordability of domestic air travel.

Commitment to Affordable Travel

The airline has committed to continuing monitoring the situation and making relevant adjustments as and when appropriate. IndiGo reiterated its dedication to offering affordable, convenient and consistent travel to customers while maintaining its position as India's preferred carrier with a fleet of 400+ aircraft operating around 2,200+ daily flights across 95+ domestic and 40+ international destinations.

InterGlobe Aviation Limited has informed stock exchanges that CRISIL Ratings Limited has placed the company's credit ratings on 'Rating Watch with Developing Implications' due to the ongoing Middle East conflict's potential impact on business and financial risk profiles.

Rating Action Details

CRISIL has placed ratings on bank facilities worth Rs 9000 crore under watch, affecting both long-term and short-term ratings:

Impact of Middle East Conflict

The rating watch reflects the persistence of the ongoing Middle East conflict, which has led to significant operational and financial challenges for IndiGo. The conflict has resulted in cancellation of substantial overseas flights to or through the Middle East, including CIS countries and Europe, which account for approximately 17% of the total available seat kilometre of IndiGo.

The conflict has driven up global crude prices substantially, with a notable increase of 60-70% over the past month. Additionally, the Indian rupee has depreciated to Rs 93.5-94.0 per US dollar from around Rs 91 at the end of February 2026.

Financial Performance Impact

These factors significantly impact aviation turbine fuel prices, which constitute 35-40% of IndiGo's total operating cost, as well as other dollar-denominated operating costs such as rentals and maintenance (35-40% of overall operating cost).

During the first nine months of fiscal 2026, revenue from operations grew 6.6% to Rs 62,524 crore, supported by healthy passenger growth across domestic and international networks despite multiple disruptions. However, the operating Ebitdar margin fell to 20% from 24.1% in the corresponding period of the previous fiscal due to external challenges and foreign exchange mark-to-market losses from rupee depreciation.

Market Position and Operations

IndiGo maintains its established market position in the Indian aviation sector with approximately 64% domestic market share between April 2025 and February 2026. The company has consistently maintained passenger load factor above 80% over the past few years and through February 2026.

Financial Risk Profile

The company maintains a healthy financial risk profile with strong liquidity position. Net debt to Ebitdar ratio was approximately 2.1 times during the 12 months through December 2025, compared to approximately 2.0 times in the corresponding period of the previous fiscal.

Leadership Transition

CRISIL has noted the appointment of Mr. William Walsh as new CEO on March 31, 2026, subject to regulatory approval, with expected joining on or before August 03, 2026. This follows the resignation of Pieter Elbers from the CEO position. In the interim, Rahul Bhatia, the current Managing Director, has taken charge of managing company affairs effective March 10, 2026.

Rating Outlook

CRISIL will continue monitoring developments regarding movement in ATF prices, currency fluctuations, grounding or re-routing of overseas flights, and their expected normalization over the near term. The rating agency will assess the likely impact on sustained demand and costs, subsequently affecting business and financial risk profiles, before taking appropriate rating action.
