Space Weather Events Could Lead to Major Costs for Airlines, Australian Experts Warn

Airlines around the world could face growing financial pressure due to space weather events, according to aviation and scientific experts in Australia. These events, which include solar storms and increased radiation activity, have the potential to interfere with aircraft systems and flight planning.

Space weather can affect satellite communications, GPS signals, and high‑frequency radio systems that pilots rely on, especially on long‑haul and polar routes. When these systems are disrupted, airlines may need to reroute flights, fly at lower altitudes, or delay departures, all of which increase fuel use and operating costs.

Australian researchers say airlines are becoming more exposed as air travel continues to rely heavily on satellite‑based navigation and digital communication tools. Even short disruptions can have a knock‑on effect across flight schedules, crew planning, and airport operations.

In some cases, airlines may also need to limit crew exposure to higher radiation levels during strong solar activity, which can further complicate scheduling and route planning. These precautions are necessary for safety but can add unexpected costs.

Experts believe better forecasting and early warnings can help airlines prepare and reduce the impact of these events. However, as solar activity increases over the coming years, the aviation industry may need to invest more in monitoring systems and contingency planning to protect operations and passengers
