What to check before booking an international flight

Confirm the entry and transit requirements that apply to your nationality, destination, route and travel dates. The U.S. Department of State’s checklist directs U.S. travelers to destination-specific requirements; it is not a substitute for the destination government’s rules for other nationalities. [U.S. Department of State](https://travel.state.gov/en/international-travel/planning/checklist.html) Next, inspect every flight and transfer. Identify the operating airline, any airport change, the arrival date and the ticket conditions you would accept if your plans changed. Check the final price in its stated currency and the services you need to add. Keep these checks separate: an airline can sell an itinerary without that purchase resolving every immigration question. Complete the document check before making a commitment you cannot comfortably change. If a requirement remains unclear, ask the competent authority about that specific itinerary rather than relying on a generic passport-validity rule.

What to do next

  1. Write out the full journey, including connecting countries and any segment you plan to buy separately.

  2. Note whether you intend to remain in transit or leave an airport.

  3. Ask the relevant authority which entry or transit rules apply to that actual plan.

  4. Record your passport expiry, the names you will use for booking and any visa or authorization already held.

Record your passport expiry, the names you will use for booking and any visa or authorization already held. Check the official destination guidance for required validity; there is no universal validity period supplied here.

Check what the ticket includes

Distinguish the airline marketing the flight from the carrier operating it. U.S. DOT guidance explains the need to identify a code-share operator during the booking process. 2 Review cabin and fare conditions for each flight, not just the most attractive part of a long itinerary. Ask whether a seat choice, bag or other needed service is included. Compare the complete price and the conditions for changes or cancellation without assuming that a fare name means the same thing across airlines.

Treat a self-arranged transfer as its own task

If you plan to travel between airports or between two cities overland, write down who books that part, who pays for it and which documents you would need. Leave yourself a plan for handling a delay; do not assume separate purchases have the protections of a single ticket.

Confirm payment and issuance

Read the checkout currency and payment method before authorizing the purchase. Save the ticket receipt, itinerary and seller contact route. If the payment appears pending but no ticket has been issued, ask the seller to check the existing transaction before attempting another purchase. A completed checklist is not an entry guarantee. Its purpose is to uncover document, connection and ticket-condition problems while you still have the option to choose a different journey.
