This Airline Has Been Forced To Ground All International Flights

Nok Air has suspended all international flights after Thailand’s aviation regulator ordered the budget airline to resolve safety and staff-related issues, according to a report by the Bangkok Post. The low-cost carrier primarily operates domestic flights but also maintains a small network of international routes.

According to the report, the Civil Aviation Authority of Thailand (CAAT) sent a letter to Nok Air’s chief executive officer (CEO), Wutthiphum Jurangkool, on August 25, 2025. In the letter, the civil aviation regulator highlighted all safety-related incidents from 2023 to 2025 that were a cause for concern.

Spike In Safety Incidents Raises Concerns

Safety concerns have grounded the budget carrier’s limited international operations, which consist of just five routes, including three to China and two to India. It is worth noting that Nok Air has not operated these flights since June 2025, citing the off-season for travel to China and India.

The Thai civil aviation regulator’s move to suspend international flights puts a halt to the airline’s plans to expand its overseas network. According to media reports, the Civil Aviation Authority of Thailand (CAAT) cited multiple safety incidents between 2023 and 2025, including in-flight engine shutdowns, runway excursions, hard landings, and tail strikes.

The most concerning issue is the unresolved cause of the in-flight engine shutdowns, which continues to raise questions about Nok Air’s operational reliability, according to the Bangkok Post. In response, the airline stated that CEO Wutthiphum Jurangkool is preparing a formal reply to the allegations and expressed confidence that the flight restrictions could be lifted within a month.

Resignations From Nok Air’s Pilots

Alongside a rise in safety-related incidents, the airline has experienced a notable wave of resignations among pilots, flight instructors, and appointed aviation inspectors. According to The Nation Thailand, this trend reflects deeper internal challenges, including the carrier’s safety culture, employee morale, and broader workforce issues.

Thailand’s aviation sector is facing a routine International Civil Aviation Organization (ICAO) safety audit conducted under the Universal Safety Oversight Audit Programme (USOAP), which assesses and monitors the aviation safety oversight capabilities. The suspension of Nok Air’s international flights is likely part of a wider push to ensure Thailand meets ICAO standards, ahead of the ICAO audit of the country’s aviation safety system, scheduled from August 27 to September 8, 2025, according to the report by The Nation Thailand.

Thailand has been upgraded to FAA Category 1 aviation safety status, moving up from its previous Category 2 rating. Officially confirmed by the US Federal Aviation Administration in April 2025, the upgrade signifies Thailand’s compliance with ICAO safety standards and permits Thai airlines to operate direct flights to the United States. The upgrade came almost ten years after the FAA downgraded the country’s status.
