The graph below demonstrated the proportion of cargo traffic between international and
domestic. It could be seen that Suvarnabhumi Airport handled the majority of cargo,
especially international, while other airports handled mainly domestic one.
While both international and domestic cargo at Don Mueang, Chiang Mai, Hat Yai, Phuket
and Chiang Rai were solely carried by combination aircraft, only international cargo at
Suvarnabhumi was handled by both combination and all-cargo aircraft (freighters).
