Guides · 4 min read

What happens if your passport has less than 6 months left

Denied boarding, refused entry, stuck at the airport — the actual consequences, country by country.

A passport that does not meet the published rule can cause problems at check-in or at the border. The outcome depends on the destination, nationality, itinerary and carrier.

At the airline check-in desk

Airlines use travel-document information to decide whether a passenger appears eligible to enter the destination. If the check fails, ask what requirement is missing and request the official source. Refund and rebooking rights depend on the ticket terms and circumstances.

At immigration on arrival

Border officers make the final entry decision. A traveller who does not meet the requirements may be refused entry and returned, but the process and costs vary. Check official guidance before departure rather than relying on a general rule.

Destinations publishing a six-month requirement

  • Thailand — check the current Thai government guidance.
  • Indonesia / Bali — check immigration and visa requirements together.
  • UAE — entry and airside-transit requirements can differ.
  • Singapore — include any stopover where you clear immigration.
  • Brazil — check rules for your passport nationality.

Where it's softer (but still risky)

  • Mexico — official rule is duration of stay, but US carriers often apply 6 months themselves.
  • Japan — duration of stay officially, but check your airline's policy.
  • EU — 3 months, not 6, plus the 10-year rule.
