A new ticket bought directly from a US carrier can usually be cancelled free within 24 hours, a window United and other airlines publish on their own booking terms. That single rule is the cheapest route to proof of onward travel you'll find anywhere, but it only covers one day. A dummy ticket, also called an onward ticket, is a real PNR booked for visa or border-check purposes without paying for the flight, and it sits alongside a refundable fare and that 24-hour window as the three main ways travellers produce a ticket they don't actually intend to fly. Picking the wrong one wastes money or leaves you exposed at the counter.
Step 1: Work Out How Long the Proof Needs to Last
Start with your calendar, not your budget. A consulate that wants evidence of onward travel weeks before your appointment needs something that will still be valid and checkable on that date. A gate agent asking at check-in needs something valid for the next few hours. These are different problems with different correct answers.
A dummy ticket typically holds as a live PNR for a matter of days to a couple of weeks, depending on the provider and the fare rule behind it. A refundable fare stays valid indefinitely, right up until you cancel or fly it. The 24-hour window, as the name says, only exists for one day after booking. Match the option to the actual gap between now and the moment someone checks your onward plans, not the other way round.
Step 2: Compare the Three Options Side by Side
| Option | Typical cost | How long it stays useful | Best suited to |
|---|---|---|---|
| Dummy / onward ticket | Low, a small booking or service fee | Days to a couple of weeks | Visa applications, border checks, check-in desks weeks or months out |
| Refundable fare | High, often several times a standard economy price | Until you cancel or fly it | Trips where your plans might genuinely change |
| 24-hour free cancellation | Full fare price, refunded if you act in time | One day from booking | Same-day or next-day proof only |
None of these is universally "best". They're tools for different timelines, and the table above is really a question about how far away your travel date sits from the moment someone wants to see the ticket.
Step 3: Understand What the 24-Hour Window Actually Covers
This is the option people misuse most often. It sounds free and official, and it is, but the coverage window is narrow. United's own refund and cancellation policy sets out how the rule applies to new bookings made directly through the airline, and it stops applying the moment that first day ends. If your Schengen visa appointment is a month away, or your flight is next week rather than tomorrow, the 24-hour window will already have closed by the time anyone looks at the ticket. It's a same day tool. Nothing more, nothing less.
There's also a practical catch: most airlines only apply the free window to bookings made straight through their own site or app, not through a travel agent or a third-party search engine. Check the specific carrier's terms before assuming it applies to your booking.
Step 4: Know When a Refundable Fare Actually Earns Its Price
A refundable fare makes sense when there's a real chance you'll fly it, or when a border or airline system specifically wants a ticket bookable and traceable straight through the carrier's own reservation flow rather than a third-party issuer. Outside that, it's an expensive way to satisfy a single checkbox. You're paying a premium specifically for the option to walk away, and you still have to go through the cancellation and refund process afterward, which can take days to land back in your account.
For a one-off visa file or a check-in desk that just wants to see a name and a date, that premium buys you very little you couldn't get more cheaply.
Step 5: Choose a Dummy Ticket for Everything in Between
Most visa and border scenarios sit in the gap the other two options can't cover well: proof needed well before or after the booking date, without tying up hundreds of dollars in a fare you don't plan to use. The US State Department's visitor visa guidance frames travel plans as part of a wider picture consular officers look at, alongside ties to your home country, rather than a single rigid document, which is worth reading directly before you assume any one paper will settle the question on its own.
A dummy ticket lives as a genuine reservation in the airline's system for as long as its fare rule allows, which is exactly why it holds up under a name-and-date check but isn't meant to become a boarding pass. Our guide to what a dummy ticket actually is covers the mechanics of how that reservation is issued and why it behaves differently from a paid fare. If you've already booked one and are wondering what happens once it's past its window, the piece on whether an airline can cancel a held reservation walks through that specific timing problem.
Why the Reservation's Status Matters More Than Its Price
Every one of these three options lives as a record inside a global distribution system, the shared booking network airlines and travel agents use to sell and manage seats. What separates them isn't cost, it's status. A refundable fare is fully ticketed the moment you pay, so it exists as a completed sale until you cancel it. A dummy ticket usually starts as a confirmed reservation that hasn't been ticketed yet, which is normal and doesn't make it fake, but it does mean the record can quietly drop or expire once its holding period runs out. A 24-hour cancellation simply reverses a ticketed sale within a carrier's own grace period. None of this changes what a border officer or check-in agent sees on screen, a confirmed booking with your name and dates, but it does explain why timing matters so much more than which option looks cheapest on paper.
Digital nomads doing repeated visa runs tend to learn this the hard way: paying for a refundable fare every few weeks adds up fast, and the 24-hour window is close to useless for a border crossing planned well in advance. A short-lived dummy ticket, timed to the actual date it needs to hold up, is usually the cheapest fix that still checks out.
