Why rising tensions in West Asia are causing flight cancellations, longer routes, and higher costs

Rising conflict in West Asia has shaken global aviation, grounding planes, changing flight routes, and increasing costs for airlines around the world. Targeted military strikes quickly led to widespread airspace closures in Iran, Iraq, and parts of the Gulf. Airlines have had to cancel hundreds of flights and reroute thousands more, affecting cities from Dubai and Delhi to Frankfurt and New York.

Global networks under pressure

Just hours after the conflict escalated, major international airlines started suspending flights or diverting planes to avoid dangerous airspace. Reuters reports that airlines such as Lufthansa and Air France-KLM have cancelled or rerouted flights over Iran and Iraq. Emirates and Qatar Airways changed their schedules amid new restrictions imposed by local authorities. Flight tracking showed planes taking longer routes over Central Asia or the Arabian Sea to avoid risky areas. Every rerouted flight takes more time, burns more fuel, and costs more money. On long flights between Europe and Asia, diversions can add 45 minutes to two hours, which disrupts crew schedules and aircraft rotations. These changes cause further problems. Planes and crews end up in the wrong places, which disrupts carefully planned schedules. The Wall Street Journal has noted that even brief airspace closures can take days to fix because flights are linked together in global rotations. Airports in the Gulf, especially Dubai International, Doha’s Hamad International, and Abu Dhabi’s Zayed International, are major global transit hubs. When these airports slow down, the effects are felt worldwide.

Gulf hubs face direct disruption

The Gulf’s aviation system relies on frequent, well-timed connections. Airlines like Emirates, Qatar Airways, and Etihad move passengers from Asia to Europe, Africa, and North America using carefully coordinated arrivals and departures. During the current crisis, several Gulf states temporarily restricted or closed airspace. According to The Guardian, debris from intercepted drones was reported near Dubai International Airport, intensifying safety concerns. In Kuwait, authorities confirmed a drone incident near the main airport. Even though some flights have resumed at times, ongoing safety concerns have led to more suspensions and major changes to schedules. Emirates and Etihad issued advisories asking passengers to check flight status before departure. Qatar Airways temporarily halted certain services as it assessed operational risks. The problem is not just physical danger but also fragile schedules. If incoming flights are late, connecting flights are missed, and this disruption spreads through the global network, affecting flights far from the conflict.

Financial strain intensifies

Besides these operational challenges, airlines are also under growing financial pressure. Brent crude prices climbed towards $80 a barrel following the escalation, according to market data cited by The Times of India. For airlines, fuel typically accounts for 25 to 35 per cent of operating expenses. Even modest oil price increases materially affect margins, particularly for carriers operating long-haul fleets. Rerouting makes things worse. Longer flights use more fuel, require crews to work longer hours, and lead to more maintenance. Insurance premiums are also likely to rise. Asia Insurance Review noted that aviation insurers tend to reassess war-risk premiums when conflict zones expand or airspace advisories intensify. Higher war-risk cover costs can add another layer of expense for airlines operating near volatile corridors. Aviation stocks have shown this uncertainty. After the conflict escalated, several airlines saw their share prices swing as investors worried about risks and lower profits.

India’s exposure to Gulf instability

India is feeling the disruption especially strongly. The Gulf is more than just a destination for India. It is the main route for travel to Europe and North America. Millions of Indian expatriate’s travels between India and the Gulf each year, and many long-haul passengers depend on Gulf airports for connecting flights. According to The Times of India, Indian airlines cancelled more than 700 flights within days of the escalation. Air India suspended several international services, including routes to London, New York and European cities. IndiGo, Air India Express and SpiceJet reported widespread cancellations to Gulf destinations. Major airports like Delhi, Mumbai, and Bengaluru became crowded as passengers tried to rebook or get refunds. Thousands of people were stranded when schedules changed with little warning. Flights from India to Europe and North America now have to take longer, less direct routes. This increases costs for Indian airlines, which already have thin profit margins. The Directorate General of Civil Aviation (DGCA) advised airlines to avoid certain Persian Gulf airspace segments, reinforcing the precautionary stance. If the disruption continues, Indian airlines could lose hundreds of crores in revenue and face extra costs. More fuel use, helping stranded passengers, and less use of planes all hurt profits quickly.

Tourism and trade implications

The problems in aviation are now affecting tourism and trade as well. The Gulf is a key link between East and West. When airports like Dubai or Doha slow down, tourism flows in and out of the region change suddenly. Travel industry executives quoted in Outlook Traveller described the current episode as one of the sharpest aviation shocks of 2026. Corporate travel has slowed as companies reassess risk. Leisure travellers are deferring discretionary trips, particularly those requiring transit through affected hubs. Tourism to India may also drop if European travellers have fewer route options or face higher ticket prices. Conferences and business events are especially affected by unreliable schedules. Cargo flights are also affected. Air freight, especially for valuable or urgent goods, depends on reliable long-haul schedules. Rerouting means longer delivery times and higher costs, which disrupts supply chains.

Structural vulnerability in a connected system

This crisis highlights a basic fact: modern aviation is highly interconnected. Aircraft operate in global rotations. A jet scheduled for Dubai–Delhi–London–New York may be disrupted at the first leg, with consequences cascading across continents. The things that make aviation efficient also make it vulnerable. Airlines use planes as much as possible, with little extra time and tightly scheduled connections to earn more money. But during conflicts, these same features make disruptions worse. Historically, aviation has rebounded after crises - from the Gulf War to 9/11 and the pandemic. The International Air Transport Association (IATA) has projected passenger growth of nearly 5 per cent for 2026, while UN Tourism forecasts international arrivals growth of 3 to 4 per cent this year. However, recovery depends on stability. Airlines can handle short-term airspace warnings, but long periods of uncertainty change routes, costs, and how people travel.

What comes next

Right now, airlines are still operating with backup plans. Flight schedules are changing every day. Regulators keep issuing new warnings, and Gulf authorities are trying to keep flights safe while maintaining connections. If tensions drop and airspace rules become stable, airlines could return to normal within days. But if the conflict grows or oil prices stay high, airlines will keep facing higher costs. For both India and the Gulf, this situation is a reminder of how much they depend on each other. Gulf airports are key for global east-west travel, and India’s long-distance growth depends on these routes. The war may be local, but its effects on aviation are clearly felt around the world.
