Trat Airport är Bangkok Airways tredje flygplats och sätter Thailands östligaste kustprovins på kartan. Flygplatsen öppnade den 31 mars 2003, främst för att trafikera sträckan till och från Bangkok. Restiden till och från huvudstaden är endast 45 minuter.
Like its older sister airports, the architecture of Trat Airport's open-air passenger terminals are built in the spirit of genuine respect for the local people, culture, and surrounding environment. The airport maintains the highest and strict safety-standards in accordance to international regulations, as well as boasting the most modern wastewater treatment facilities.Trat Airport's aim is to improve business links with the eastern provinces of Thailand and the neighboring Chantaburi province. It also acts a hub to the popular resort island of Koh Chang and its neighboring islands. With its unspoiled beaches and a plethora of Thai delicacies to be found, Trat Airport achieves to release the provinces' tremendous tourism potential.Future plans for the airport involve introducing services to other important business centers and tourist destinations in Thailand's south and northeast regions. The potential for including Trat on twin or multiple center itineraries also appears excellent considering the fact that popular resort destinations of Koh Samui and Phuket are just a little more than an hour away.
