Nan hotel operators say the government's postponement of the Thai Thiao Thai Plus travel subsidy to April clashes with the northern season, when PM2.5 haze keeps tourists away and April is usually renovation time. They want more quotas, a longer programme, simpler registration and face scanning, and a cheaper flight subsidy (about 500 baht suggested) for secondary cities. They also propose seasonal budgeting, with the north favoured in green season and rainy months. If you run a northern hotel or tour business, plan for a later subsidy window and the possibility that the scheme stays thin; this is a proposal, not a rule change.
