If you arrive without proof of onward travel, you may face:

Denied boarding by the airline at your departure airport
Secondary inspection at immigration, causing delays of 1–4 hours
Denied entry and placement on the next available return flight (at your expense)
Visa cancellation or a re-entry ban in serious cases
Shorter stay granted (e.g., 15 days instead of 30)

FlightProof provides instant onward tickets that satisfy both airline check-in systems and immigration requirements worldwide. Your booking comes with a PNR-style booking reference and itinerary PDF delivered to your email within minutes.
