Proof of Travel
Writer
Former corporate travel compliance officer at a Big 4 firm. 11 years.
Henrik spent over a decade inside a Big 4 firm's travel and risk function in Geneva, where 'proof of travel' meant something legally specific. He writes about onward tickets and dummy reservations from the compliance angle: what airlines, employers, and consulates actually accept as evidence.
Proof of onward travel means different things to an airline check-in desk, a border officer, and a consulate, and a document built for one does not always satisfy the others.
Nicaragua is the fourth true CA-4 signatory alongside Guatemala, Honduras, and El Salvador, and the agreement does not remove the onward or dummy ticket check required at first entry to the zone.
Honduras runs flights through three airports and shares a 90-day CA-4 clock with its neighbors, and an onward ticket has to satisfy both the airline and that shared timeline.
El Salvador belongs to the CA-4 border bloc, but that shared zone doesn't remove the onward ticket check at your first port of entry. Here's what actually gets verified, and by whom.
Belize sits outside the CA-4 agreement, so its Guatemala border and Belize City airport each run independent onward-ticket checks for visa-exempt visitors.
A dummy ticket only proves onward travel while its underlying PNR is live in the GDS, so understanding status codes and ticketing deadlines matters more than the printout itself.
Tanzania checks for proof of onward travel at check-in and immigration alike, and a dummy ticket, also called an onward ticket, is the document that satisfies it.
Thailand's visa-exemption scheme requires proof of onward travel, but enforcement varies by checkpoint. A compliance case study walks through booking, check-in, and arrival requirements.
When the exit plan is overland, the onward-ticket check happens at the inbound check-in desk, not the land border. A compliance breakdown.
One-way digital nomads face proof-of-travel checks at check-in, immigration, and on visa forms. Here is how a dummy or onward ticket fits each checkpoint.
A KLM check-in dispute shows why an onward ticket and a return ticket satisfy different requirements, and how a ticketed PNR resolved the confusion at the gate.
A Thailand border run to Laos or Cambodia rarely triggers an onward ticket check at the land crossing, but the flight home almost always does.
