PATTAYA, Thailand – Cambodia has announced the closure of its airspace only along the border area due to recent unrest near the Thai-Cambodian border, issuing a NOTAM (Notice to Airmen) on July 25, 2025. Thailand has also issued a NOTAM for a related airspace area on its side.
However, the Civil Aviation Authority of Thailand (CAAT) confirms that this restricted airspace is limited and does not affect air traffic to and from Thailand. Flights can safely reroute around the restricted zone, so domestic and international flights continue operating normally without significant delays or cancellations at Thai airports.
Surachai Nooprom, Acting CEO of Aeronautical Radio of Thailand Ltd., stated that air traffic management has been adjusted to avoid conflict zones to ensure safety. Currently, flights between Thailand and Cambodia remain stable.
Chai Eamsiri, CEO of Thai Airways, said that demand for flights from Phnom Penh remains moderate with around 50-60 seats still available. Thai Airways is ready to adjust aircraft sizes accordingly. Bangkok Airways also maintains readiness to assist Thai nationals wishing to return, offering flights to Siem Reap (3 flights) and Phnom Penh (2 flights). Thai nationals seeking to return can contact airlines or the Royal Thai Embassy in Phnom Penh for assistance.
Meanwhile, Ubon Ratchathani and Buriram airports in Thailand continue normal operations with increased security and coordination with local authorities to monitor the situation.
Regarding Thai Airways’ Bangkok–Phnom Penh route between July 27-31, 2025: flights TG586/TG587 will operate normally with larger aircraft to accommodate passengers, while flights TG584/TG585 are temporarily suspended.
