Pattayas' Utapao International Airport is aiming to draw more regular international flights following its million expansion is completed in 2013.
Work is currently scheduled to begin in 2011 and will feature building a new terminal which will hold 1,500 passengers. The current capability is 400 passengers.
The existing 3,5km runway and apron for 49 aircraft is not planned to be upgraded as they can already accommodate all types of aircraft.
Association of Thai Travel Agents (ATTA) committee member Thongyoo Suphavittayakorn is reported to have said the upgraded airport would attract flights from Pattaya's key markets - Russia and the Commonwealth of Independent States (CIS), India, South Korea and China.
Lao Airlines launched a new twice-weekly service from Vientiane to Utapao in November, while Bangkok Airways already operates domestic flights to Koh Samui to Utapao and Phuket to Utapao services.
