The draft law sets a cap of 5,000 baht per trip, and the first phase proposes 1,000 baht per air trip, collected by airlines and ticket agents with the fare. A Chula economist argues the real burden depends on how far airlines can pass it on to fares. Thin-margin low-cost routes may be cut, and the cost could reach hotels, tour operators, restaurants and provincial tourism businesses. If your business depends on short-haul travellers or tourism, watch the consultation and plan for softer demand, not just a higher ticket price.
