Book something now, then read the rest. If you're flying into Bolivia on a one-way ticket with no onward proof, the fastest fix is a short-hold onward ticket booked through a dedicated service, ready in minutes, or a refundable flight held directly with your airline. Both create a real, checkable PNR. A free generator PDF doesn't, and that's the document that gets people held up at La Paz's El Alto or Santa Cruz's Viru Viru. Here's what to do depending on how much time you've actually got.

A dummy ticket, also called an onward ticket, is a real booking in the airline's system, obtained without paying for the flight, used to prove you're not staying in Bolivia indefinitely. That's the thing to have. Not a PDF that looks like one.

If you're at the check-in counter right now

Don't argue with the agent. Pull up a booking app on your phone and reserve a short-hold onward ticket while you're standing there. Most services confirm within a couple of minutes and hand you a real PNR the airline can look up immediately. Show the confirmation, not a screenshot of a search page. If the agent is using a system like IATA's Timatic to cross-check your documentation, a confirmation number that resolves to an actual booking is what gets you cleared to board.

If you've got an hour before your flight

You have time to do this properly. Book a refundable flight directly with an airline you're likely to actually fly again, one with a genuine free cancellation window. Hold it, screenshot the confirmation, and cancel it later once you're past both checkpoints. Alternatively, use a short-hold onward-ticket service instead and skip the cancellation step entirely. Either way, do it now rather than hoping the question doesn't come up.

If you're already through security with nothing booked

Use the airport wifi. A short-hold onward-ticket booking takes a few minutes on a phone and doesn't require you to be at a desk. Have the confirmation ready before you're at the gate, not while you're standing in the boarding line. Gate agents move fast. Give yourself the buffer.

If Bolivian immigration has already flagged you

At El Alto or Viru Viru, a flag usually means a short secondary conversation, not an automatic refusal. Stay calm and have your phone ready. If you can produce a genuine onward booking on the spot, most of these situations resolve quickly. A vague explanation and no document is what turns a five-minute stop into a much longer one. Bolivia's own entry framework is enforced with officer discretion rather than a single fixed rule, something the UK Foreign Office's Bolivia travel advice reflects too, so a real document you can hand over does more work than an argument.

If you're heading onward overland

Bolivia borders five countries: Peru, Chile, Argentina, Paraguay and Brazil. If your plan is to cross by land rather than fly out, the onward-ticket question doesn't disappear, it just moves. Land posts are staffed and resourced differently from the two main airports, so don't assume a bus ticket or a verbal plan will do the job a booked reservation would. If Peru's on your route, the requirement there works the same way: check it before you're standing at the crossing. Crossings like Desaguadero on the Peru border or Villazon on the Argentina side get less consistent staffing attention than the two main airports, which cuts both ways. It's not a guarantee you'll be waved through, and it's not a guarantee you won't be asked. Carry the same document you'd carry through an airport.

If you're working remotely and passing through more than once

Don't reuse the same booking across separate entries. Each time you land in Bolivia is a fresh check, and a reservation you already flew, or one that's simply expired, won't hold up the second time any better than a generator PDF would. Book a new short-hold onward ticket for every entry. It takes a few minutes and it keeps every arrival equally clean, instead of betting a whole trip on one document doing more work than it can.

If you're not sure which airport applies to you

La Paz's El Alto and Santa Cruz's Viru Viru handle the bulk of international arrivals, and both run the same basic check, an airline document review before boarding, followed by an immigration review on arrival. Neither airport is more lenient than the other in any way you should plan around. Treat both exactly the same: have a real booking ready before you're anywhere near the counter.

What actually works, by how fast you need it

Option Time to get it Works at check-in Works with immigration
Free generator PDF Instant No No
Short-hold onward ticket A few minutes Yes Yes
Refundable flight, booked direct 10 to 20 minutes Yes Yes
Nothing, verbal explanation only N/A Inconsistent Inconsistent

The fix, one more time

Book a real onward reservation before the question gets asked, not after. It's faster than any argument you could make at a counter.

Once you're through, verify your onward ticket PNR to confirm it's actually holding, and if Peru's next on the route, check what Peru asks for before you get there.

Book an onward ticket now, while you've still got time to do it properly.
