The couple – Thananaj Chaikhunthira, 31, and Kulpakorn Chaijit, 36 – were arrested at Hat Yai International Airport, along with Chatchai Benjapitporn, 31, and Chattraporn Jaidee, 28.
Police said the four suspects had split up and travelled on two flights, with each of them carrying some of the illegal drugs.
Police said that after receiving tip-offs, they had been monitoring the group for five days and made the arrests when they were about to leave Hat Yai airport.
They added that the couple were allegedly major drug dealers in Hat Yai, who had hired Chatchai and Chattraporn to help them transport the pills and crystal meth from Don Mueang International Airport to Hat Yai.
