Ten farmers travelled by van and pickup truck to the departure gates at the airport with donation boxes to find support for their campaign for overdue payments after pledging their rice to the caretaker government. Those donating money received a small token made of rice straw.
They spent about 30 minutes at Suvarnabhumi with security provided by airport police and Suvarnabhumi staff before leaving to join other farmers in a rally in Bangkok.
Thongchai Kanchananukul, a leader and former Moo 5 village chief in Phanom Thuan district, Kanchanaburi, said the farmers wanted to show visitors to Thailand the problem of the rice-pledging scheme.
The caretaker government has promised to start paying farmers with pledging papers on Monday.
But Mr Thongchai said they will continue to rally against the caretaker government until they receive all of the money they are owed, he added.
