Major airline that flies from Heathrow cancels flights in May - all 46 routes listed
The international airways has notified travel agents that it will cancel flights and reduce frequencies on both domestic and world routes across Asia and Europe
A major airline that also operates out of London Heathrow is set to dramatically cut its flight schedule as soaring energy costs begin to bite.
Thai Airways International has notified ticket agents that it will axe flights and slash frequencies across both domestic and international routes throughout Asia and Europe in May 2026. A total of 46 services have been affected.
The timetable shake-up comes amid surging fuel prices worldwide, driven by the ongoing conflict in Iran. The US and Israel have carried out joint strikes on several key Iranian targets since hostilities began on February 28. While a short-term ceasefire is currently in place, a lasting peace agreement has yet to be secured.
Iran hit back by striking targets across the Middle East and shutting down the vital Strait of Hormuz trade route.
The US has since enforced a blockade on Iranian ports within the strait in a bid to end the closure and push forward negotiations.

Approximately 20% of all global oil trading passes through the Strait of Hormuz, and its closure has sent shockwaves through international oil markets, pushing fuel prices sharply higher.
Thai Airways cited escalating oil costs and weakening passenger demand during the low tourism season as the primary factors behind the decision, according to The Nation.
The airline confirmed that alternative arrangements have been put in place to support agents and passengers.
