A familiar autumn ritual is under strain this Dasain, Nepal's biggest festival, when tens of thousands of families traditionally head abroad for a holiday. Thailand has long been a favourite, but a change in how Bangkok handles Nepali visa applications has pushed the country's travel trade to the brink of a boycott.

The Nepal Association of Tour and Travel Agents (NATTA) says its members will stop selling Thailand packages during the Dasain season unless the rules are relaxed. The sticking point is upfront payment: applicants now have to book and pay for hotels and flights before their visa is even considered. If the visa is refused — and there is no guarantee it won't be — the agent is left carrying the cost, with little recourse. For an agency booking dozens of festival-season trips, a handful of rejections can wipe out a month's margin.

The frustration isn't abstract. Martin Lama, a manager with Thai International who has spent 30 years working in Kathmandu, was himself turned down for a Thai visa. If a three-decade veteran of the airline industry can't get approval, agents argue, what chance does an ordinary family with a modest income and a short travel history?

Thailand isn't alone. The UAE has also tightened entry procedures for Nepali visitors, adding a second squeeze on outbound holiday traffic from Nepal at exactly the moment demand peaks. For Kathmandu's agencies, the double hit lands on two of the most popular short-haul destinations for Nepali travellers — Dubai and Bangkok are the classic Dasain getaways.

For travellers, the practical lesson is to assume more friction this season. Prepaid bookings mean you're financially exposed before you know you can travel, so book refundable rates and flexible tickets where you can, keep every document consistent between your application and your reservations, and consider working through an agent who can flag applications likely to raise red flags. If a refusal looks possible, travel insurance that covers cancellation costs is worth the extra spend.

Why it matters: visa policy is quietly becoming the biggest variable in South Asian outbound travel. Prepayment requirements shift all the risk onto the traveller and the agent, and responses like NATTA's threatened boycott show how quickly that can turn into fewer flight options and higher prices for everyone. Whether you're a Nepali family planning a festival break or a business watching the route, keep an eye on how the standoff between Kathmandu's agents and Bangkok resolves — the outcome will shape what's on sale next season.
