Passenger information: what needs to match?

Passenger information feels administrative until something does not match. Airlines and border systems use these details to decide whether you can check in, board, or enter a country. Small spelling issues can become slow airport problems.

What to do first

  • Compare the booking name with the travel document.
  • Update missing passport or ID details before check-in.
  • Use a reachable phone number and email.
  • Check every passenger, including children.

Step-by-step instructions

  1. Step 1

    Read the name exactly as the airline displays it. Middle names, accents, hyphens, and order can matter depending on the airline and country.

  2. Step 2

    Check date of birth, nationality, document number, expiry date, and issuing country against the passport or ID.

  3. Step 3

    If advance passenger information is requested, complete it before check-in so document review is not rushed at the airport.

  4. Step 4

    For name mistakes, contact the airline or seller early. Do not wait for online check-in if the name is clearly wrong.

  5. Step 5

    If your passport is new, update saved profiles so the old number is not reused by mistake.

  6. Step 6

    Keep copies of confirmations after any correction.

Common mistakes

  • Using a nickname

What to do next

Once details match, continue to document rules and check-in timing. Correct information reduces friction, but it does not replace visa or entry checks.
