What to do if…
your child’s travel document details do not match the booking and you are about to check in

Short answer

Don’t complete check-in yet—get the airline to correct the passenger details on the reservation/ticket so they match your child’s travel document. Go straight to the airline (or operating carrier) and ask for a typo/data correction for the same passenger.

Do not do these things

  • Don’t “guess” which version of your child’s details will work and keep trying variations—this can create conflicting records that are harder to fix quickly.
  • Don’t assume it’s fine if the surname/first name or date of birth is wrong—airlines commonly require these to match the travel document for check-in/boarding.
  • Don’t buy a brand-new ticket in a rush until you’ve asked whether the airline can do a correction or reissue (fees/rules vary).
  • Don’t shorten or rearrange a double-barrelled surname, or swap name order “to make it look right”—use what’s on the travel document.
  • Don’t split up from your child while you fix this—you may need them present to show documents, answer questions, or sign anything the airline requires.

What to do now

  1. Identify exactly what’s wrong (2 minutes, character-by-character).
    Using your child’s travel document photo page, compare:

    • first name(s) and surname (including hyphens, apostrophes, spacing)
    • date of birth
      For many trips, these are the main blockers. Passport/document number and expiry often matter most for international travel and Advance Passenger Information (API/APIS).
  2. Check whether it’s a “formatting difference” or a real mismatch.
    Some systems drop accents/diacritics or squeeze spaces. If the underlying letters match and it’s just accent marks or spacing, tell staff that the booking system has “normalised” characters. If letters are missing/added or names are swapped, treat it as a real mismatch.

  3. Work out who can fix it fastest: seller vs operating airline.

    • If you booked with a travel agent/website, they may “own” the ticket and be the only one who can reissue it.
    • If the flight is a codeshare, the operating airline is the one you must be able to check in with—go to that airline’s desk.
  4. Go to a staffed airline desk (or urgent support) and use the right wording.
    Say: “This is the same child passenger. We need a typo/data correction to match the passport/travel document—this is not a ticket transfer to another person.”
    Have ready:

    • booking reference(s) and e-ticket number (if you have it)
    • your child’s passport/travel document
    • a screenshot/photo of the incorrect booking details (if available)
  5. Ask for the least disruptive fix first, then the next option.

    • Minor correction/typo correction (where allowed under the fare rules/airline policy)
    • If they can’t edit the ticket details directly: reissue/revalidate the ticket with the corrected passenger details (this may involve a fee and/or fare/tax difference)
    • If they say it’s not possible: ask for the official options (same-day rebooking, later flight, new ticket) and what happens to the old ticket value
  6. If check-in time is tight, do two things at once without creating chaos.

    • Stay in the airline help line/desk queue while (if there’s another adult) someone calls/chat-supports the seller/airline.
    • Keep one “source of truth” (one corrected spelling/DOB written down) and don’t authorise multiple different changes.
  7. If the mismatch is because the travel document itself is wrong, assume it won’t be fixable at the airport.
    In the UK, document corrections typically require HM Passport Office processes/appointments rather than an on-the-spot airport fix. In that case, focus on the airline’s rebooking options now, and deal with document correction separately once you’re out of the immediate time pressure.

What can wait

  • You do not need to decide who made the mistake or argue with the seller at the airport—prioritise getting a valid check-in/boarding pass outcome.
  • You do not need to start refunds, complaints, or insurance claims right now—just keep documents, screenshots, and receipts.
  • You do not need to fix every profile detail (frequent-flyer account, saved passengers) today unless staff say it’s directly blocking the correction.

Important reassurance

This is a common problem—especially with children’s multiple given names, hyphenated surnames, and booking forms that truncate or alter characters. The quickest way through is one calm, authorised correction rather than repeated DIY edits.

Scope note

These are first steps for the next hour. If travel is missed or costs are incurred, you may need follow-up with the airline/travel agent and (if relevant) your insurer after the urgent moment has passed.

Important note

This guide is general information, not legal advice. Airline policies and fare rules vary, and acceptance of any correction ultimately depends on the airline operating your flight and the ticket rules for your booking.
