The government is hoping to see air travel soar following the ending of the Test & Go requirements.
The Civil Aviation Authority of Thailand expects 83,500 flights per month at all airports by year's end, up from 44,500 at present, following the easing of Covid-19 restrictions.
Significant jumps are expected in both international and domestic flights, a government spokeswoman said.
The Test & Go entry requirements were lifted on Sunday to woo more international tourists and help the kingdom compete with regional tourism rivals like Indonesia, Vietnam and Singapore.
Tourism operators and travellers have complained about the continued need to register for the Thailand Pass before arriving in the country, urging the government to scrap it too.
The first day after the departure of Test & Go saw about 17,000 air travellers arrive on 96 international flights at Suvarnabhumi and a further 4,000 from 27 landings at Phuket airport, according to the Transport Ministry.
