Passengers intending to take domestic or international flights out of Bangkok are being advised to allow 3 hours before boarding time for travel to Suvarnabhumi or Don Mueang airports.
The advice was separately issued by Thai Airways International, Thai Smile, Thai Air Asia, Thai Air Asia X, Nok Air and Thai Lion Air.
The advice applies from today (Tuesday) until November 20th, one day after the end of the APEC Summit in Bangkok.
The airlines explained that, due to the closure of several roads in Bangkok as part of the security arrangements for APEC leaders, traffic flow in the capital is affected and this may lengthen journeys from hotels to the two airports.
