Thai Airways International has announced an increase in fuel surcharge rates on international tickets, driven by a worsening global aviation fuel crisis linked to escalating conflict in the Middle East. The airline says the revised charges will apply to tickets issued on or after 1 May 2026, while bookings made on or before 30 April 2026 will retain the current lower surcharge even if travel occurs later.

The airline confirmed that the new surcharge rates will be almost 100% higher, effectively doubling this portion of the ticket cost for passengers on major international routes including Bangkok to London, Tokyo, and Sydney. The adjustment reflects rapidly rising operational costs as jet fuel prices continue to surge worldwide.
Thai Airways said the increase has been triggered by a sharp escalation in aviation fuel prices caused by ongoing conflict in the Middle East. Jet A-1 fuel prices have reportedly risen to two to three times previous levels. Fuel typically accounts for up to 30% of airline operating costs, making the spike financially significant for carriers.
The airline stated that the surcharge revision is necessary to align ticket pricing with current market conditions and ensure operational sustainability. It emphasised that the changes are unavoidable given the scale of cost pressure across the aviation sector.
The announcement comes amid broader operational adjustments by Thai Airways, which has already reduced flight frequencies and cancelled selected domestic and international services during April in response to escalating costs. The airline has been attempting to balance capacity with financial pressures while maintaining core routes.
Passengers planning future travel have been advised that timing of ticket purchase will determine whether the higher surcharge applies. Those who secure bookings before the cut-off date will avoid the increased charges, regardless of their travel schedule.
The Nation reported that the airline is expected to continue monitoring fuel price volatility closely, with further adjustments possible if global energy markets remain unstable. The situation may also influence demand patterns, particularly on long-haul routes where fuel costs have the greatest impact on fares.

Bangkok-Yangon: from 1,780 to 3,390 baht for economy class and from 2,580 to 4,930 baht for business class
