Thai Airways International, a major airline operating out of London Heathrow, is set to reduce its flight operations significantly due to energy-related challenges. The airline has notified ticket agents about its decision to cancel flights and decrease frequencies on various domestic and international routes throughout Asia and Europe in May 2026, affecting a total of 46 services.
This reduction in flight schedules is a response to the surge in fuel prices globally, attributed to the ongoing Iran war. Recent joint strikes by the US and Israel on key Iranian sites since the conflict began on February 28 have escalated tensions. While a temporary ceasefire is in effect, a lasting peace agreement remains elusive.
In retaliation, Iran has targeted sites across the Middle East and blocked the vital Strait of Hormuz trade route. Consequently, the US has imposed a blockade on Iranian ports in the strait to reopen the passage and push for diplomatic negotiations.
With approximately 20% of the world’s oil trade passing through the Strait of Hormuz, the trade route closure has had a significant impact on global oil markets, leading to increased fuel prices. Thai Airways cited rising oil costs and reduced passenger demand during the off-peak tourism season as the main reasons for its operational adjustments, as reported by The Nation.
The airline has assured that alternative arrangements are in place to support affected agents and passengers. Both domestic and international routes have experienced cancellations or frequency reductions as a result of these operational changes.
