"Visa on arrival" sounds like the easy option: no embassy, no appointment, just a counter at the airport. The catch is that most arrival schemes still want to know how you will leave, and the first person to ask is usually not an immigration officer but the airline agent at your departure gate. This guide sets out what official sources say about return and onward tickets for the visa-on-arrival countries our readers ask about most, who checks, and where a flight reservation is and isn't enough. Official sources sit behind every rule, and deeper country guides are linked along the way.
Visa on arrival and onward tickets: key facts
| Country | Arrival option | Official wording on leaving |
|---|---|---|
| Thailand | Visa on arrival, up to 15 days, tourism only (currently for a short list of nationalities); 30-day visa-free entry for 60 countries and territories.[1][10] | VOA: "Fully paid onward travel tickets scheduled within 15 days". Visa-free: "proof of onward travel scheduled within 30 days".[1] |
| Indonesia | Visa on arrival (VOA), electronic VOA (e-VOA) or visa-free visit, depending on nationality.[3] | Imigrasi lists a return, or travel on to a third country, under all three routes.[3] |
| Maldives | Tourist visa on arrival; GOV.UK describes it as 30 days.[4][5] | "Confirmed return journey tickets", plus prepaid accommodation at a registered facility.[4] |
| Nepal | Visa on arrival, with an online form up to 15 days ahead.[6] | No onward-ticket requirement in GOV.UK's entry page.[6] |
| Cambodia | E-visa or visa on arrival, 30 days for tourists.[7] | Not mentioned in GOV.UK's entry page.[7] |
| Laos | Visa on arrival at listed airports and checkpoints, 30 days.[8] | Not mentioned in GOV.UK's entry page.[8] |
Is visa on arrival the same as visa-free entry?
No, and the difference matters for your ticket. Visa-free (or visa-exempt) entry means your nationality needs no visa at all for a short tourist stay. Visa on arrival means you do need a visa, but you get it at the border, usually by filling in a form and paying a fee. An e-visa is applied for online before travel. Thailand shows all three side by side: most visitors from eligible countries come in visa-free for 30 days, a handful of nationalities use a 15-day visa on arrival, and everyone else applies for a visa in advance.[1]
Exit-proof rules often get tighter as you move from visa-free to visa on arrival. Thailand is a good illustration. The visa-free scheme wants evidence you'll move on inside 30 days. The arrival visa demands onward tickets that are "fully paid" and dated inside 15 days, funds of 10,000 baht each (20,000 for a family), with a 2,000 baht fee payable in cash.[1] If your passport puts you in the arrival-visa group, plan around the stricter wording.
What do the main visa-on-arrival countries ask for?
Thailand
Thailand changed its entry schemes on 15 September 2026, cutting the standard visa-free stay to 30 days for tourism only and restructuring the visa-on-arrival list.[10] The Royal Thai Embassy in London lists the visa on arrival as a stay of up to 15 days, for tourism, with onward tickets paid in full and dated inside that period, and says it cannot be extended except for illness.[1] The Thai embassy in Vienna, updated in September 2026, names Azerbaijan, Belarus and Serbia as the visa-on-arrival nationalities and phrases the ticket rule as "a confirmed return ticket, or proof that you will exit Thailand within 15 days of entry".[2] Every arriving traveller also completes the free Thailand Digital Arrival Card within 3 days before arrival.[1] Full detail: onward ticket for Thailand and Thailand visa guide.
Indonesia, including Bali
Indonesia's immigration directorate uses near-identical wording for all three short-stay routes. For the e-VOA it asks for a "return ticket or onward ticket to continue traveling to another country"; the paper VOA and the visa-free visit carry the same requirement in substance, alongside a passport valid for at least six months.[3] Note what the rule does not say: it doesn't require a flight, and it doesn't fix a number of days. Our onward ticket for Bali and Indonesia guide covers the arrival card and Bali levy, and the Indonesia visa guide covers the visa itself.
Maldives
The Maldives is the strictest of the group on paper. Maldives Immigration asks for a complete travel itinerary "including confirmed return journey tickets", prepaid, confirmed accommodation at a registered facility, and sufficient funds. Your passport must be machine-readable and valid for one month or more, and every foreign arrival submits the Traveller Declaration within 96 hours before arrival.[4] Entry is granted at the port of entry, at the officer's discretion. See dummy ticket for Maldives visa.
Nepal, Cambodia and Laos
For these three, the official pages we could check do not mention an onward ticket. GOV.UK says Nepal's visa on arrival can be applied for online up to 15 days ahead and collected at the airport, with stays extendable up to 150 days in a year.[6] Cambodia offers an e-visa or a visa on arrival, valid for 30 days, plus an e-Arrival Card for air arrivals within 7 days before travel.[7] Laos issues visas on arrival at listed airports and checkpoints for 30 days, and warns of a heavy fine and a ban for long overstays.[8] Silence on a government page doesn't mean your airline won't ask, as the next section explains. Country guides: Nepal, Cambodia, Laos.
Who checks your onward ticket: the airline or immigration?
Both can, at different moments, and the airline usually goes first. Before letting you board, check-in staff compare your passport and documents with the destination's entry requirements, typically through IATA's Timatic database.[9] If the destination lists a return or onward ticket as a condition, an agent may ask for one before printing your boarding pass. Then, on arrival, the immigration officer has the final say, and in the Maldives the government page states plainly that admission is decided at the port of entry.[4]
The two checks feel quite different in practice. This is our experience of how they usually play out, not an official rule:
| Point of check | What they look at | What usually satisfies them | Risk if you can't show it |
|---|---|---|---|
| Airline check-in | Destination rules in the airline's systems; your booking out | A booking with a name, date and reference within the allowed stay | Boarding refused at your home airport |
| Immigration on arrival | Visa conditions, funds, accommodation, exit plan | Whatever the official wording names, e.g. "fully paid" for Thai VOA | Entry refused and return at your expense |
| Transit airline | The same rules, for the next sector | Documents for the final destination | Offloaded mid-journey |
For a closer look at the difference, read airline check-in vs immigration onward ticket checks, and if it has already happened to you, denied boarding without an onward ticket.
Is a flight reservation enough for visa on arrival?
It depends on the exact words, and we'd rather tell you straight than oversell. A held reservation exists in the airline's system with a working PNR, yet nobody has paid for it, so it can't be flown.
- Where the wording is simply "proof of onward travel" or a ticket home or onward, with no mention of payment, a reservation you can verify shows your exit plan and is often what travellers use at check-in. Thailand's visa-free scheme and Indonesia's routes fall in this group.[1][3]
- Where the rule says "fully paid" or "confirmed", a held reservation may not satisfy it. Thailand's visa on arrival ("fully paid onward travel tickets") and the Maldives ("confirmed return journey tickets") are in this group.[1][4] For these, buy a real, ideally refundable or cheap, exit ticket.
- Where nothing official is published, as with Nepal, Cambodia and Laos on GOV.UK, the airline's own policy decides. A reservation is a sensible back-up if your route is one-way.
Our honest view: for a one-way trip into Thailand or Bali on a visa-free basis, a reservation for your exit flight is a practical answer to a check-in question. For a Thai visa on arrival or the Maldives, spend the money on a real exit ticket. Turning up with less than the official wording asks for is a risk that sits entirely with you.
Your options compared
| Option | Cost | Shows a live booking | Meets "fully paid" wording | Best for |
|---|---|---|---|---|
| Flight reservation (held, not paid) | ₹699 / $9 per passenger | Yes, with a PNR | No | Visa-free entries and "proof of onward travel" wording |
| Cheap one-way exit ticket | Fare price | Yes | Yes | Thai VOA, the Maldives, fixed plans |
| Fully refundable fare | Higher fare, refund later | Yes | Yes | Strict wording with uncertain plans |
| Bus, train or ferry ticket out | Varies | Depends on operator | If paid | Land borders; see onward travel by bus, ferry or train |
Getting ready for a visa-on-arrival flight
- Confirm which scheme your passport uses. Visa-free, visa on arrival or e-visa: the official page for your destination will say.
- Read the exit wording. Note whether it says paid, confirmed, or just proof, and how many days.
- Choose your exit document. A reservation where the wording allows it; a real ticket where it asks for payment.
- Book an exit date inside the allowed stay. Leave a day or two of margin for a delayed flight.
- Complete the arrival form. TDAC for Thailand within 3 days, the Maldives declaration within 96 hours, Cambodia's e-Arrival Card within 7 days.[1][4][7]
- Carry cash for the fee and funds. Thailand's VOA fee is cash only, and GOV.UK suggests US dollars as back-up in Nepal.[1][6]
- Keep everything offline. A PDF and a printout of your exit booking, hotel and arrival form.
A small example shows how this fits together. Say you hold a passport eligible for Thai visa-free entry and fly Delhi to Bangkok on 4 December, planning to cross into Laos by land around 20 December and fly home later. The Thai rule asks for onward travel within 30 days, so an exit booking from Bangkok on or before 2 January covers it, and a reservation dated 20 December, matching your plan, is honest and fits the window. We'd book it two or three days before departure and check it on the airline's site the night before.
Mistakes that cause trouble at the gate
- An exit date beyond the allowed stay. Day 17 on a 15-day Thai VOA fails the rule even if the booking is real.
- Old information. Plenty of pages still quote Thailand's 60-day allowance, which ended on 14 September 2026.[1]
- A reservation where payment is required. Read the wording for the Maldives and the Thai VOA carefully.
- A name that doesn't match the passport. Airline systems compare them directly.
- A booking that has lapsed. Holds expire within two weeks, sometimes sooner depending on the carrier, so book near departure.
- Forgetting the arrival card. Some airlines ask to see it before boarding.
Getting an onward reservation
Our held exit bookings come with a working PNR in your name, for whatever route out and date you choose. With no fare paid, it isn't a ticket, and you can't board using it. Expect the email in about ten minutes; after that, the reservation appears when you search it on the airline's "Manage booking" page. Our verification steps explain the lookup.
One fee per traveller covers a one-way or a return, as the price page lists.

Flying one-way on a visa-free or arrival scheme?
A held booking out of the country, live PNR in your name. ₹699 / $9 per passenger.
Remember: the airline decides whether you board and the immigration officer decides whether you enter. Where the rules ask for a paid ticket, buy one.
Frequently asked questions
Do I need a return ticket for a visa on arrival?
For most schemes, yes, or an onward ticket to another country. Indonesia asks for a return or onward ticket, Thai arrival visas need onward tickets already paid for and leaving inside 15 days, and the Maldives insists on confirmed return tickets. GOV.UK's pages for Nepal, Cambodia and Laos do not mention one, but airlines may still ask.
Will a dummy ticket work for a Thailand visa on arrival?
Probably not on its own. Thailand's rule for arrival visas requires onward tickets paid in full within the 15 days, and a held reservation is unpaid. For the 30-day visa-free scheme, where you only need evidence of moving on inside 30 days, a verifiable reservation is a more reasonable fit.
Can I use a reservation for Bali's visa on arrival?
Indonesia's immigration directorate wants either a ticket home or one to a third country, without saying it must be paid or naming a deadline. Many travellers show a verifiable reservation at check-in. The airline and the officer in Bali decide whether it is acceptable, so carry it with your hotel details.
Why does the airline ask for an onward ticket if immigration doesn't?
Airlines check passengers against destination entry rules before boarding, typically using IATA's Timatic database. Some agents apply those rules cautiously, especially for one-way passengers. That is why a one-way passenger can be questioned at check-in even when the destination's own page says little.
How many days after arrival should my onward flight be?
Within the stay your scheme allows: 15 days for the Thai visa on arrival, 30 days for Thai visa-free entry, and the visa length elsewhere. Leave a day or two of margin for delays, and make sure the date matches your actual plans.
Is the Maldives stricter than other arrival countries?
On paper, yes. Maldives Immigration wants "confirmed return journey tickets", accommodation that is prepaid and registered, funds, and a Traveller Declaration in the 96 hours before you land. A held flight reservation may not meet "confirmed", so buy a real exit ticket.
What if I am refused boarding without an onward ticket?
Ask the agent exactly what they need, then book it quickly if time allows. If the destination accepts proof of onward travel, a reservation emailed in about 10 minutes may resolve it; where payment is required, buy a cheap or refundable exit fare. Our guide on denied boarding goes further.
