Why it may be requested

Airlines check travel documents because they can be responsible for carrying an ineligible passenger. Border officers may also ask about departure plans, funds and accommodation.

What document is accepted?

One authority may require an issued ticket, another may accept a reservation, and another may not ask in your case. Check the exact official wording and do not substitute a reservation when it explicitly requires a ticket.

Review the full itinerary

Check transit-country requirements too, especially when changing airports or collecting and rechecking baggage. Keep documents available offline and confirm that they remain valid on travel day.

Quick checklist

  • Check rules for your nationality, destination and visa.
  • Ask the airline what it accepts at check-in.
  • Review transit-country requirements.
  • Carry valid evidence on travel day.
