What to do if…
your travel booking has the wrong date of birth and check-in is coming up

Short answer

Fix it before you travel: airlines use passenger data (including date of birth) for TSA Secure Flight screening, so contact the airline (or whoever issued the ticket) now and get the DOB corrected in the reservation.

Do not do these things

Don’t ignore it and assume it won’t matter—airlines commonly collect DOB for Secure Flight screening on covered flights.
Don’t make a duplicate booking for the same passenger as a workaround unless the airline tells you to—duplicates can create new check-in problems.
Don’t change only a stored profile and assume the trip record changed; you need the DOB corrected on this reservation.
Don’t rely on online check-in if the system is rejecting you—switch to resolving it with the issuing party or ask for the airport desk plan.
Don’t cancel in panic if you’re close to departure—confirm the airline’s correction/reissue options first.

What to do now

Identify who can edit the reservation today.
- Booked direct: contact the airline.
- Booked via an OTA/travel agent: contact the agent first if they issued the ticket (airlines often can’t change third-party ticketed records).
Use the key phrase: “Secure Flight passenger data.”
Ask them to correct the DOB in the reservation/ticket record so it matches your government ID, and confirm whether the ticket needs to be reissued after the change.
Check for an age-category mistake (infant/child/adult).
If the wrong DOB puts someone in the wrong age category on the travel date, you may need a fare adjustment or ticket reissue. This is a common reason online check-in fails.
If you have TSA PreCheck and it’s missing, treat that as a warning sign.
A mismatch in name/DOB (or a Known Traveler Number entered differently than your enrollment) can result in PreCheck not appearing on your boarding pass. Ask the airline to confirm the DOB and that your KTN is entered exactly as issued.
If they can’t fix it immediately, get the airport plan in one sentence.
“Can a ticket counter agent correct the DOB at the airport for check-in, and how early should I arrive to do that before security and boarding?”
Prepare a ‘proof pack’ you can show quickly.
- Bring the physical ID you will use at the airport (passport or state ID/driver’s license, as appropriate).
- Keep your confirmation email, record locator, and any chat/email showing you reported the error.
- If you have PreCheck: your KTN details exactly as issued.
If you hit a wall, document it for later—but keep your focus on travelling today.
Save timestamps, names, and written responses. After travel (or if you can’t travel), you can file a complaint with the airline/ticket agent and, if still unresolved, submit a DOT consumer complaint.

What can wait

You don’t need to decide today whether you’ll dispute charges, complain to regulators, or pursue refunds/fees.
You don’t need to “prove fault” right now—your only urgent objective is getting the DOB corrected in the active reservation so screening/check-in can proceed.
You can sort out compensation and formal complaints after you’re through travel day.

Important reassurance

This is usually an administrative fix. The fastest path is getting the DOB corrected by the party that controls the ticketing/reservation, then re-checking that your reservation details match your ID.

Scope note

These are first steps for the immediate, high-stress window before check-in and departure. If you end up with fees or a refusal to correct obvious errors, you may want consumer help after the trip (or after you’re safe at home).

Important note

This is general information, not legal advice. Airline systems and fares differ, and some corrections may require reissuing tickets or paying fare differences—follow the instructions the airline/agent gives for your specific booking.
