⚠️ Key Rule
K-ETA is mandatory since 2023 for visa-exempt countries. Apply at least 72 hours before. Without it, boarding is denied.
Vizum ≠ vstop. Vizum omogoča le vkrcanje in vlogo — mejni policist odloči, kdo vstopi, in zahteva dokazilo, da boste odšli. Povratna vozovnica FlightProof je to dokazilo: eno najcenejših dokazil o nadaljnjem potovanju na svetu — najnižja cena za vašo pot. Izdano v manj kot minuti. Pojdite skozi imigracijo in uživajte v vizumu.

Why airlines refuse boarding without an onward ticket
Flying to a high-risk country? The airline — not immigration — checks you before boarding, and it will not board you even when you never show a "when is your return flight" ticket at the border. The reservation out is exactly what we confirm: any route out, on the date you choose — that's it. Immigration passed: how long you stay depends on the entry stamp you receive.
Officer: “When is your return flight?”
You: “In two weeks — here is the booking.”
Stamp. Entry granted. That was the only question, and you had the answer ready.
Win-win: you buy a ticket out just to come in, you never fly it, and there is nothing to cancel afterwards — no fare held, no refund to chase. The officer gets a straight answer; you keep your plans.

Kje bodo zahtevali dokazilo o nadaljnjem potovanju
Osebje letalske družbe vidi mednarodno vozovnico in pred izdajo vstopnega karte običajno preveri dokazilo o nadaljnjem potovanju.
Na nekaterih izhodih osebje znova preveri potne dokumente — pripravljena vozovnica prepreči ponovna preverjanja in zamude.
Uradniki za priseljevanje lahko vprašajo, kako in kdaj boste zapustili državo.
Nekatere okenca za vizum ob prihodu zahtevajo vozovnico za odhod kot del pogojev za vstop.
