Three bus routes linking U-tapao with three eastern provinces have been introduced to serve passengers and promote the airport in Rayong.

The Land Transport Department and the Royal Thai Navy jointly introduced the bus routes from the airport to Trat, Ranong and Chonburi.

The service to Trat includes Chanthaburi on one of its stops, while the Chonburi route also stops in Pattaya and Sri Rachat.
