A war 2,500 kilometres away is about to show up on your flight booking screen. Air India announced on March 10 that it will implement phased fuel surcharges starting March 12, ranging from ₹399 on domestic routes to $200 on North America and Australia legs. The trigger: aviation turbine fuel prices have surged sharply since early March 2026 as the Strait of Hormuz — the world's single most critical oil chokepoint — ground to a near halt following joint US-Israel military strikes on Iran. When a waterway carrying roughly 20% of global daily oil supply effectively closes, the economics of every airline that burns jet fuel start to unravel fast.
The Core Problem
Aviation turbine fuel, or ATF, is not a peripheral cost item for airlines. Air India itself confirmed in its March 10 press release that ATF accounts for nearly 40% of its operating costs — one of the highest cost-to-revenue ratios of any industry. When that input price spikes 10–13% in a single trading day, as Brent crude did upon news of the Hormuz closure (Wikipedia, March 2026), an airline cannot simply absorb it. Margins that were already thin go negative.
Air India's surcharge structure reflects the severity. Phase 1, effective March 12, charges ₹399 on domestic and SAARC routes, $10 on West Asia flights, $60 on Southeast Asia, and $90 on Africa routes. Phase 2, from March 18, adds $125 on European routes and $200 on North America and Australia. A third phase covering Far East markets — Hong Kong, Japan, South Korea — remains pending.
The financial pain does not stop with ATF prices alone. In India, high excise duty and VAT on jet fuel in metro cities like Delhi and Mumbai act as a multiplier, making every 10% rise in global crude prices hit Indian carriers roughly 12–15% harder than their international peers. This structural tax burden has been a long-standing grievance for Indian aviation. The Gulf conflict didn't create that vulnerability — it just exploited it with maximum force. The real question is not whether fares are rising. They already are. The question is how high they go if the Strait stays closed.
Historical Parallel
The last time global oil markets faced a comparable shock, the calendar read February 2022. Russia's invasion of Ukraine sent Brent crude racing above $130 per barrel by March 8, 2022 — the highest price since 2008 and a gain of nearly 70% from January levels. Indian carriers faced a brutal ATF cost surge. IndiGo, SpiceJet, and Air India all scrambled to introduce fuel surcharges that year, ranging between ₹250 and ₹2,000 per ticket depending on sector distance.
The key financial lesson from 2022: surcharges introduced as 'temporary' measures rarely disappear quickly. SpiceJet maintained elevated fare structures for over five months after crude peaked, as hedging costs, debt servicing, and ongoing fuel volatility prevented any meaningful price rollback. IndiGo's EBITDA margin compressed by nearly 8 percentage points in Q1 FY23 compared to the prior year, according to its investor disclosures.
Go back further and the 1973 Arab oil embargo is the starkest parallel. That shock — a supply cut of roughly 7% of global output — sent crude prices up 300% and triggered a global aviation industry contraction that lasted nearly three years. The 2026 Hormuz closure is cutting roughly 20% of global seaborne oil supply, a far larger percentage. History does not repeat perfectly, but the directional pressure on airline economics is unmistakable: when energy supply shrinks this fast, someone always pays. That someone, almost always, is the passenger.
The Data Under the Hood
The numbers behind Air India's surcharge decision are stark. On March 9, 2026, Brent crude hit a session high of $119.50 per barrel — its highest level since Russia's invasion of Ukraine in 2022 — before partially retreating to approximately $87–88 per barrel by March 10–11 as Trump made verbal interventions signalling a potential Hormuz reopening (CNBC, March 10, 2026). WTI crude posted its biggest-ever single-week gain of 35.6% in the week ending March 9 (EBC Financial Group data, 2026). Even at the retreated $87–88 level, crude remained nearly 40% above the pre-crisis baseline that IEA and J.P. Morgan had projected for full-year 2026, which was $58–$60 per barrel.
Goldman Sachs, in an analysis published March 4, estimated an $18-per-barrel geopolitical risk premium embedded in current crude prices — a premium that feeds directly into ATF procurement costs for any airline purchasing fuel on spot or short-dated contracts. Goldman separately revised its Q2 2026 Brent forecast upward by $10, to $76 per barrel, even under a relatively benign baseline scenario where Hormuz disruptions ease within four weeks (Reuters, March 4, 2026).
The Strait itself is the critical variable. According to EIA data cited by Al Jazeera, approximately 20% of global daily petroleum demand — and one-fifth of global LNG supply — transits through Hormuz. Tanker traffic reportedly fell by roughly 90% within days of the IRGC's closure warning, with over 150 ships anchored outside the waterway. In India's case, the exposure is disproportionate: India imports approximately 80–85% of its crude needs, with the Gulf accounting for the majority of that supply. Rystad Energy's vice president for oil markets noted in a March 9 client note that if current conditions persist for two months, Brent could exceed $110 — a level at which airline ATF costs in India would likely make the current surcharges look modest.
Two Sides of the Coin
The bull case for a quick resolution: Diplomatic signals from Washington suggest Trump wants the conflict over fast. The president publicly stated he was 'nowhere near' ordering ground troops into Iran (CNBC, March 10), and indicated Iran was seeking talks. If a ceasefire agreement materialises within three to four weeks — Goldman Sachs' baseline scenario — Hormuz traffic could partially normalise, Brent could retrace toward the $70–76 range, and ATF costs would moderate. In that scenario, Air India's Phase 2 surcharges, announced for March 18, might never be collected at full rate on a large volume of bookings. Aviation stocks could recover sharply as investors price in margin normalisation.
The bear case, however, carries more financial weight right now. Allianz Research published a scenario analysis on March 3 showing that a prolonged Hormuz disruption could send Brent above $130 per barrel — and potentially to $135 if disruptions persist for four months (Rystad Energy, March 9). At $130 Brent, Indian ATF prices, already amplified by domestic excise duty, could render several short-haul domestic routes economically unviable — exactly the scenario Air India alluded to when it said some flights might face cancellation without the surcharge.
The bear case isn't just about airline P&L. Persistently high oil translates into broader inflation. India's consumer price index is sensitive to fuel costs; diesel and kerosene feed into the rural economy. If crude holds above $100 through Q2 2026, the RBI's rate-cutting path — already calibrated for a benign energy environment — faces a serious obstacle.
Scenarios & What-Ifs
Three forward-looking scenarios frame the financial trajectory from here:
Scenario 1 — Rapid De-escalation (probability: moderate). A US-Iran deal materialises within 3–4 weeks. Hormuz reopens progressively. Brent retreats to the $70–76 range by late April 2026. Air India rolls back or reduces Phase 2 and Phase 3 surcharges. Aviation load factors, temporarily suppressed by sticker shock, recover into the summer season. This is Goldman Sachs' baseline, but the market is not fully pricing it.
Scenario 2 — Prolonged Standoff (probability: moderate-to-high). No deal before mid-April. Brent consolidates between $90 and $110. Air India retains all surcharges; rival carriers — IndiGo, Akasa, SpiceJet — follow with their own fee structures. Domestic fares rise 12–18% by April end. RBI holds rates, and travel demand in leisure segments softens noticeably.
Scenario 3 — Escalation Spiral (probability: lower, but material). Iranian attacks on Gulf energy infrastructure expand. Saudi Arabia or UAE production faces physical damage. Brent breaks above $130. ATF costs in India become structurally prohibitive for narrow-margin carriers. One or more Indian airlines suspends routes. This is the tail risk — lower probability, but the financial damage would be severe and lasting.
The Bottom Line
Air India just passed the Gulf war's bill to you — ₹399 to $200 extra per ticket depending on where you're flying. This is not a temporary inconvenience; it's a structural cost transfer that will stick as long as Hormuz stays disrupted. Watch crude prices daily: if Brent stays above $90 through late March, expect every Indian airline to follow Air India's lead.
