Low-cost carrier Thai AirAsia is increasing frequencies on three key domestic routes from June 1 despite continuing political unrest in the country.
Services will be doubled from the existing daily frequencies on the Bangkok-Ubon Ratchathani and Phuket-Chiang Mai routes, and the Phuket-Udon Thani route will go daily, up from four times a week.
Thai AirAsia is promoting the extra services with a raft of online promotions.
Meanwhile, Airports of Thailand (AOT) is planning a package of measures designed to support airlines and tenants at its facilities, including Bangkok's international airport, as airline traffic is expected to show a major dip with the continuing political crisis.
The measures will lower landing and other charges in a bid to encourage international airlines to maintain their services to country.
Several countries including the US, UK and Australia have issued advice to their citizens to avoid all but essential travel to the country.
