Nepal's main gateway, Tribhuvan International Airport (KTM), sees plenty of one-way arrivals from trekkers with no fixed exit date. That's exactly the profile that gets questioned. A dummy ticket, also called an onward ticket, is a real PNR booked for visa or border-check purposes without paying for the flight. Here are five things to sort before you fly.

1. The airline asks before Nepal does

You meet two gates, not one. The first is the check-in desk at your departure airport. The second is immigration on arrival.

Desk agents often check entry conditions against the IATA Timatic database, and they care about one thing: will you be refused at the other end? If they think yes, you don't board. Simple as that.

Gate staff work to a script. They scan your passport, pull up the destination rules, and look at your itinerary. A one-way booking into a country that asks for proof of exit is the sort of mismatch that stops a boarding pass printing. It's nothing personal, and it's rarely negotiable.

So plan for the desk first. If your documents can't survive the person with the keyboard, the immigration queue never matters.

2. Read the official page for your passport

Nobody can promise you a single rule for every nationality. Look up your own. British passport holders can use the UK government's Nepal entry requirements page, and other governments publish equivalents.

Check what it says about visas, passport validity and any proof of onward travel. If onward travel isn't mentioned, don't relax. Airlines can apply their own caution regardless of what a government page lists.

Note the date you checked. Pages change.

It also pays to read the whole page, not just the headline. Entry pages often cover health requirements, passport condition and what to do if you're refused entry, and those details can matter as much as the visa line. If anything on the page is unclear, ask the airline or the relevant embassy before you buy a seat, because afterwards the options narrow quickly.

3. Your exit date must fit a trek-shaped trip

Nepal trips are lumpy. You might plan two weeks, then extend for weather, permits or a flight delay out of the mountains. An onward booking has to be fixed to a date, so choose carefully.

A trek is also a reason people end up with a vague plan. Vague plans read badly at a desk. Agents want a date, a place and a reference they can see on a screen.

Pick a departure that sits inside the stay you expect to be granted. Too early looks thin. Too far out looks careless. If you do extend, handle it through the proper official channel, then update your plans.

4. Land exits count differently than you think

Many travellers enter Nepal by air and leave overland, or the reverse. Don't assume a bus ticket will satisfy an airline desk. Agents generally look for something they can verify in a reservation system, and a printed bus slip usually isn't.

If you really are leaving by land, say so honestly, and ask the airline what documentation it accepts before you reach the airport. If it wants a flight booking, a dummy ticket is the usual way to cover that request without paying for a flight you won't take.

Is that legal? In general it's a question of presenting it honestly. Our piece on whether a dummy ticket is legal goes through the common concerns. It isn't legal advice, and you should check the rules for your own situation.

Consider your connections too. If you transit through a third country, the rules of that stopover can apply as well, and the desk at your first airport may check the whole itinerary. A booking that covers only the last leg can leave a gap.

5. Carry it three ways

Screens die. Wi-Fi vanishes. Agents ask at the worst moment.

  • Save the confirmation as a PDF on your phone.
  • Keep a printed copy in your passport folder.
  • Email it to yourself so you can reach it from any device.

Know the details cold: your name as in the passport, the route, the date and the booking reference. Short, consistent answers beat long explanations every time. If the officer asks where you're going next, give the same city that's on the booking.

If something doesn't match, don't argue at the desk. Ask what they'd accept, fix it, and move on.

Before you go

Run this quick pass. Your name matches the passport. The date sits inside a believable stay. The route leaves Nepal. You've read your own government's page this month.

A last word on tone. Be polite, be brief, and don't volunteer a long story. Gate staff handle hundreds of passengers, and a clear, boring answer is the one they remember least and wave through fastest.

That's it. It isn't glamorous, but it's the difference between boarding smoothly and standing at a desk with a queue behind you. To get a verifiable booking in place, book your onward ticket here.
