We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Carrier service and weekly frequencies are summarized from our flight-schedule database, which draws on published airline timetables, U.S. government schedule data, and observed operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI).

Taxis and ride-share services like Grab are widely available and cost around 65–100 MYR, taking forty-five to seventy minutes depending on traffic. Car rentals are available at the airport but are less practical for city travel due to congestion.
