You're flying to Mauritius on a one-way fare, maybe via Dubai on Emirates or direct from Paris on Air Mauritius, and you haven't booked the flight home. That's normal. It's also the exact situation that gets travellers pulled aside at the check-in desk before they ever see Sir Seewoosagur Ramgoolam International (MRU). 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 seven things you need to get right before you hand over your passport, grouped by when they matter.

Before you book: three things to know

1. The airline asks first, not Mauritius

You'll probably meet the onward-ticket question in your departure city, not at MRU.

Airlines have to carry passengers who meet the destination's entry conditions. If they fly someone who's refused entry, they're usually responsible for flying that person back. So the desk agent in London, Paris, Johannesburg or Dubai is the real checkpoint. They'll look at your one-way booking and ask how you're leaving the island.

Have the answer ready. Don't make the agent dig for it.

This matters more on long-haul routes with a connection. If you're flying London to Dubai to Mauritius, the agent in London is checking you against Mauritius, not Dubai. Your final destination is what counts.

2. Mauritius is an island. Your exit is a flight.

There's no land border. No bus out. No train.

That means your proof of exit has to be a flight, and it has to look like one a real traveller would take. Good options:

  • Back to your home region, through a hub like Dubai, Paris or Johannesburg.
  • A short regional hop to Réunion, which is a common onward stop for island-hoppers.
  • A flight on to another Indian Ocean destination if that's genuinely where your trip goes next.

What doesn't work well: an exit to a random city with no link to your trip, or a date that clearly doesn't fit what you've told the agent.

3. The rules live on official pages, so read them

Don't trust a forum post from three years ago. Entry conditions change.

If you hold a British passport, the gov.uk entry requirements page for Mauritius covers what visitors need on arrival, including passport validity and what officers may ask you to show. Other nationalities should check their own government's version. Read it in the week you fly.

The pattern across many island destinations is consistent: officers want to know you can support yourself, where you're staying, and that you'll leave. Expect all three questions, even if you only get one.

When you book: three mistakes to avoid

4. Your name has to match. Exactly.

This is the mistake that bites hardest at the desk.

The name on your reservation must match your passport, character for character. That includes:

  • Middle names, if your passport shows them.
  • Hyphens and double surnames.
  • The spelling in the machine-readable lines at the bottom of the photo page.

If the agent types your surname and the booking doesn't come up, you've got a problem that no printout fixes. Check it the moment you book.

5. A dead PNR is worse than no PNR

Reservations don't live forever. Holds expire.

If you booked your onward reservation six weeks ago and fly tomorrow, there's a real chance it's already gone. Then you're standing at the desk showing a PDF for a booking the airline's system can't find. That looks bad, even though it isn't dishonest.

Here's the fix:

  • Book close to your departure date.
  • The day before you fly, enter the reference and surname on the airline's "manage booking" page.
  • If it won't load, sort it out that night, not at the airport.

Our breakdown of six ways a valid onward ticket fails at the gate goes deeper on what agents actually see when they pull a booking up.

6. Keep the date inside your stay, with room to spare

Your exit date should sit comfortably inside the stay you're allowed. Don't push it to the last possible day. Don't set it a year out.

A week or two after your arrival is easy for an agent to accept. Something that looks like it overruns your permitted stay is the fastest way to get a second question, and maybe a supervisor.

If your plans are open-ended, pick a sensible date anyway. You can change your real travel plans later. The reservation just needs to show a believable departure today.

At the desk: the last thing, and the fallback

7. Have the rest of the pack ready too

An onward ticket rarely travels alone at MRU. Officers commonly ask about accommodation and funds as well.

Have these ready before you land:

  • Your accommodation address, with a confirmation you can show on your phone.
  • Your onward reservation, as a PDF and a printout.
  • A way to show funds if asked, such as a bank card and a recent statement on your phone.

Keep your answers short. "Two weeks in Grand Baie, then flying to Réunion" is a perfect answer. A long story isn't.

The same pack works well across the region. If you're combining islands, the checklist in six desk things for the Maldives shows how the questions shift slightly from one island nation to the next.

When it goes wrong

Say the agent still isn't happy. What now?

Ask exactly what they'll accept. Some airlines want a fully paid ticket. Some will accept a flight on their own network. Some will accept a reservation once they can see it in the system. Get a clear answer, then decide.

Stay polite. You can ask for a supervisor if you believe your documents meet the requirements, and that's a normal request, not a confrontation. Arguing doesn't change the agent's checklist. Clear documents do.

If you want to see how an airline's own policies frame this, look at the travel documents section of your carrier's site. Emirates, for example, publishes visa and passport guidance for passengers on its own pages. That's the airline's view of what it expects you to carry.

The short version

You're flying one-way to Mauritius. The desk will probably ask how you're leaving. Have a live reservation in your exact passport name, dated inside your stay, on a route that makes sense. Bring your hotel details. Answer in one sentence.

That's the whole job. Don't overthink it.

One last tip: keep everything in one place. A single folder on your phone with the passport scan, the exit booking, the hotel confirmation and a bank statement means you're never scrolling through email while an agent waits. Print the two that matter most, the exit and the hotel. Phones die. Paper doesn't.
