An estimated 726,000 air passengers are expected to travel on domestic and international flights in the country this month, or about 24,200 per day, according to Airports of Thailand (AoT).

The AoT predicts only one-third of the total estimate, approximately 270,500, will be passengers on international flights operated to and from Thailand; the rest will be travelling via domestic flights.

A total of 31 inbound flights carrying about 2,600 passengers landed at Suvarnabhumi International Airport on Tuesday, the second day of the country's reopening, according to airport general manager Kittipong Kittikachorn. Of those passengers 1,500 were foreign nationals, he said.

Regarding the shortage of transfer buses experienced on day one of the reopening, he said the airport has worked with hotel operators to resolve the problem.

Also at Suvarnabhumi on Monday, more than 30,000 people registered and were approved for automated Covid-19 safety clearance under the Thailand Pass system, which is compulsory for visitors arriving in the country.

Under the system, now in place at all international airports in Thailand, passengers' vaccination documents are checked and verified using a QR code
