What to do if…
your travel booking lists the wrong country of citizenship and you cannot edit it online

Short answer

Treat this as a passenger-data/APIS fix: contact the airline (or the agent you booked through) and ask them to correct your nationality/citizenship details to match your passport, and be ready to have it corrected at the check-in desk if online changes are locked.

Do not do these things

  • Don’t cancel and rebook in a panic unless the airline/agent tells you it’s the only fix (you could lose money and still face the same document checks).
  • Don’t change nationality/citizenship fields to “get past the form” if it would change visa/ETA/entry requirements for your destination or transit points.
  • Don’t assume it’s harmless if your route involves visas, transit rules, or return travel to the UK.
  • Don’t share passport scans via insecure channels or with unknown “booking fix” services.
  • Don’t leave it to the gate—if you can’t check in online, fixes are usually easiest at staffed check-in.

What to do now

  1. Pin down what’s wrong (nationality/citizenship vs passport details).
    Some systems store “country of citizenship/nationality” separately from “passport issuing country.” Write down what the booking shows and what it should be, exactly as on the passport you’ll travel with.
  2. Save proof and your references.
    Screenshot the passenger details page and any “can’t edit” message. Keep your booking references (airline record locator/PNR and, if different, the travel agent reference).
  3. Contact the party that can actually amend the record.
    • If you booked direct with the airline: ask the airline to update your Advance Passenger Information (API/APIS) / travel document details on the booking.
    • If you booked via an online travel agent/tour operator: contact the agent first; they may need to push the correction into the airline booking record.
  4. Use wording that avoids being misrouted into “name change.”
    Say: “My reservation shows the wrong country of citizenship/nationality and I can’t edit it online. Please update my passenger/API details to match my passport.” Ask for written confirmation of what they changed.
  5. If they say it can’t be changed online, plan an airport correction early.
    Some airlines will correct nationality/citizenship at the check-in desk rather than online. Arrive earlier than normal and go straight to staffed check-in (not only self-service bag drop).
  6. If you’re travelling to the UK as a British citizen (including dual nationals), check what you’ll present to the carrier.
    Carriers commonly do pre-departure document checks for UK-bound travel. GOV.UK lists acceptable documents for British citizens entering the UK (for example a valid UK passport, a Gibraltar identity card, or a certificate of entitlement showing right of abode). It also notes that some dual citizens may be able to travel with an expired UK passport or an emergency travel document in certain situations—so if your UK passport isn’t available, don’t guess: check GOV.UK guidance and raise it with the airline before travel.
  7. If you’re abroad and travel is soon, prepare a “check-in pack” you can show quickly.
    Have ready (paper or offline on your phone): passport(s) you will travel on, any visas/permissions for your route, booking references, and the message trail showing you tried to correct the record.

What can wait

  • You do not need to decide now whether to complain, seek refunds, or change providers—focus only on aligning booking data with your travel document so you can board.
  • You don’t need to resolve every immigration edge case right now; the immediate goal is: correct passenger data + correct documents in hand.

Important reassurance

This kind of data error is common and usually fixable by the airline/agent updating your passenger/API details, or by a correction at check-in. Acting early and keeping your documents consistent is what prevents last-minute surprises.

Scope note

These are first steps only—intended to reduce risk of denied boarding and stop panic decisions. If your itinerary involves visas, complex transit, or multiple passports, you may need route-specific advice later.

Important note

This is general information, not legal advice. Airline policies and border/document checks vary by route and traveller status. If the wrong citizenship/nationality could affect whether you need a visa/permission for any part of your journey, treat correction as time-sensitive and use official guidance for your exact route.
