[citation needed] Air traffic control was provided by CATS (Cambodia Air Traffic Services), with full approach and aerodrome VHF facilities housed in the control tower between the fire station and the domestic terminal.

[13] CATS are also responsible for clearing takeoffs and landings of tourist helicopters from the “Big Balloon” site, 3 km away, near Angkor Wat.

Runway alignments were 23 & 05, with only 23 being used for takeoff, due to flight restrictions over Angkor temple.

The outbound flight from Siem Reap operated via Phuket, while the inbound one was nonstop.
