A wrong date of birth in an airline reservation can prevent online check-in, delay the issue of your boarding pass, or force an airline agent to review your booking. The correction process depends on who issued the ticket, how soon you depart, and whether another airline operates part of the trip. Check the error early and use the steps below to correct it.
Quick Answer
Contact the airline or travel agency that issued your ticket and ask it to correct the date of birth in your Secure Flight passenger information. Some airlines let you update the information online, but others require an agent. Keep your booking code and government-issued identification ready, then verify the corrected reservation before departure.
Key Takeaways
- Correct the birthdate through the airline or ticketing agency that controls the reservation.
- An online profile update may not change a ticket that has already been issued.
- Call immediately when departure is within 72 hours because self-service options may be limited.
- Check every segment on codeshare or multi-airline itineraries after the correction.
- Use TSA for checkpoint and identification questions, not for editing an airline reservation.

Why Your Birthdate Matters for Air Travel
For flights within, into, or out of the United States, airlines collect Secure Flight passenger information. The required data normally includes your full name, date of birth, gender, and an optional redress number. American Airlines explains these requirements in its Secure Flight guidance.
Your airline sends this information to the Transportation Security Administration (TSA) for passenger screening. An incorrect birthdate may prevent online check-in, cause the reservation to return for further review, or require an airline agent to correct the record before issuing a boarding pass.
Age also matters for infant and child bookings. For example, an infant who travels without a separate seat may follow different ticketing rules from a child age two or older. These rules vary by carrier and itinerary. A birthdate error can therefore place a young traveler in the wrong passenger category.
A birthdate typo does not automatically cancel a trip, but it can stop a reservation from moving smoothly through check-in and passenger screening.
How to Update Your Birthdate with the Airline
What You Will Need
- Your booking reference or confirmation code
- Your ticket number, when available
- A passport or other government-issued identification showing the correct date of birth
- The name of the airline, travel agency, or website that issued the ticket
- Documents proving the traveler’s age when the booking involves an infant or child
- Legal name-change documents only when the passenger’s name also needs correction
-
Compare the reservation with the travel document. Check the month, day, and year carefully. Confirm the passenger’s name, date of birth, gender, passport information, and Known Traveler Number where applicable.
-
Identify who issued the ticket. Look at your confirmation email or card statement. Contact the airline when it sold the ticket directly. Contact the travel agency or online booking company when that company issued it.
-
Check the manage-booking page. Sign in to the airline’s website or app and look for “Manage Trip,” “Passenger Information,” “Secure Flight Information,” or “Profile.” Some airlines let you add or update passenger data online.
-
Contact an agent if the field is locked. Tell the agent that the passenger is the same person and that you need a date-of-birth or Secure Flight passenger-data correction. This helps distinguish a correction from an attempt to transfer the ticket to another traveler.
-
Provide proof when requested. The airline may ask you to upload or present a passport, driver’s license, birth certificate, or another document that confirms the correct birthdate. Follow the airline’s secure document-submission instructions.
-
Check partner-airline segments. For a codeshare or multi-airline itinerary, ask the ticket issuer to confirm that the corrected information reached every operating carrier.
-
Review the corrected confirmation. Confirm the full birthdate, passenger name, passport details, Known Traveler Number, and all flight segments. Save the email or screenshot showing the change.
Pro Tip: Updating your frequent-flyer profile does not always update an existing reservation. Open the trip itself after changing your profile and confirm that the corrected information appears there.
What to Do When Your Flight Leaves Soon
Call the ticket issuer immediately when departure is within 72 hours. Do not rely only on email or a web form. Some airline systems limit self-service edits as departure approaches because passenger data has already entered the screening process.
Ask the agent whether you can check in online after the correction. When the airline cannot confirm that online check-in will work, arrive earlier than usual and bring the identification or supporting document used for the correction.
Warning: Do not wait until the boarding gate to report the error. Gate staff may have less control over ticket records than reservations or airport ticket-counter agents.
Potential Consequences of Incorrect Birthdate Information
The result depends on the airline, route, traveler’s age, and how close the flight is. A minor typo may only require a quick correction. A locked or inconsistent record may prevent online check-in and require an agent to verify the traveler’s information.
For an international trip, the airline may also compare the reservation with passport and advance passenger information. A difference between these records can create an additional check before the airline accepts the passenger for travel.
Warning: A birthdate error does not guarantee denied boarding, but the airline may require a correction before it completes check-in or issues a boarding pass.
How a Wrong Birthdate Disrupts Your Travel Plans
| Where the Error Appears | Possible Problem | Best Action |
|---|---|---|
| Current reservation | Online check-in may fail or require manual review | Contact the ticket issuer and request a Secure Flight data correction |
| Frequent-flyer profile | The wrong information may populate future bookings | Correct the profile and separately check existing trips |
| Infant or child booking | The traveler may appear in the wrong age category | Provide proof of age and confirm the correct ticket type |
| International passenger data | The reservation may not align with the passport record | Correct both the reservation and passport-data entry |
| Travel insurance policy | The insurer’s traveler record may contain the wrong age or identity detail | Ask the insurer to correct the policy and confirm the update in writing |
A delayed correction can affect the rest of your schedule when it causes you to miss check-in deadlines or spend extra time at the ticket counter. The error itself does not automatically cancel hotel or tour reservations, but a missed flight can create secondary problems throughout the itinerary.
What Documents You Need to Update Your Birthdate
The exact document depends on the airline and the type of traveler. A passport is usually the clearest document for an international reservation. For a U.S. domestic trip, the airline may accept another government-issued document that shows the correct birthdate.
Since May 7, 2025, travelers age 18 and older who use a state-issued driver’s license or identification card at a TSA checkpoint need a REAL ID-compliant card or another document on the TSA list of acceptable identification.
A birth certificate can help establish a child’s age or support a correction, but it is not a substitute for the identification an adult must present at a TSA checkpoint. TSA generally does not require children under 18 to show identification for domestic travel, although the airline may request proof of age or identity.
Note: A marriage certificate or court order is normally relevant only when the passenger’s legal name also changed. It does not by itself prove that a birthdate was entered incorrectly.
Products Worth Considering
Optimal Lighting Conditions: Ensure well-lit surroundings to avoid shadows or uneven lighting that can affect the clarity of the passport photo. Use natural light if possible, or position artificial lighting strategically to minimize harsh shadows on the face.

How to Stay Compliant with TSA Security Rules
Your airline collects and transmits Secure Flight passenger data. TSA uses that information as part of passenger screening, but TSA does not normally edit the reservation for you.
Before travel, compare the reservation with the identification you plan to present. Check the passenger’s full name, date of birth, gender, and Known Traveler Number or redress number where applicable. For an international trip, also check the passport number, nationality, expiration date, and issuing country.
Contact the airline or ticketing agency when the reservation is wrong. Contact AskTSA or the TSA Contact Center when you need help with acceptable identification or checkpoint procedures.
How Birthdate Errors Affect Your Loyalty Points and Rewards
A birthdate typo does not normally erase miles or points. The larger risk is that incorrect information saved in a frequent-flyer profile may copy into future reservations or create trouble when the airline verifies the account.
Correct the loyalty profile and then open each existing booking separately. Confirm that the reservation still contains the right frequent-flyer number and Known Traveler Number. A profile correction does not always update a ticket that has already been issued.
When you use TSA PreCheck, Global Entry, NEXUS, or SENTRI, make sure the name and identity details in the booking remain consistent with the trusted-traveler account. Also confirm that the Known Traveler Number still appears after the airline changes the reservation.
What a Wrong Birthdate Means for Your Travel Insurance
A birthdate error on an airline booking does not automatically cancel travel insurance. However, insurers often collect each traveler’s date of birth, and age can affect pricing or eligibility under some plans. Travel Guard includes traveler birthdates among the information needed when arranging coverage and notes that age commonly affects plan cost.
Review the declarations page or confirmation document for your policy. When the birthdate is wrong there, contact the insurance provider and ask it to correct the traveler record. Request an updated policy document or written confirmation.
Coverage decisions depend on the terms, conditions, and exclusions of the specific policy. Do not assume that an airline correction automatically updates a separately purchased insurance plan.
Why International Travelers Need Accurate Birthdate Details
International itineraries involve more than the Secure Flight record. Airlines may also collect passport and advance passenger information for border authorities. The birthdate, name, passport number, nationality, and document expiration date should match the passport used for the trip.
When another airline operates part of the route, ask the ticket issuer to confirm that the corrected data reached the operating carrier. Recheck the reservation through each airline’s website when possible.
Visa, electronic travel authorization, or immigration records may be separate from the airline booking. Correcting the reservation does not automatically change an ESTA, visa application, or other government travel record.
When and How to Contact TSA About a Birthdate Mismatch
Contact the airline or ticketing agency first when the birthdate is wrong in the reservation. TSA cannot normally open the airline booking and edit it.
Contact TSA when you have questions about acceptable identification, checkpoint screening, or what to bring to the airport. AskTSA is available through text and social channels, and the TSA Contact Center handles screening and identification questions.
A simple reservation typo is not usually a reason to file a redress request. The DHS Travelers Redress Inquiry Program is intended for travelers who repeatedly experience misidentification, unexplained additional screening, delayed boarding, or similar government-screening problems.
Tips for Keeping Your Birthdate Information Current
- Review every passenger’s information before paying for a ticket.
- Check the confirmation again after receiving the ticket number.
- Correct saved airline and travel-agency profiles so the error does not repeat.
- Do not assume a profile update changed an existing reservation.
- Check codeshare and partner-airline segments separately.
- Confirm the Known Traveler Number and frequent-flyer number after any correction.
- Keep the corrected confirmation available on your phone and in your email.
Pro Tip: Review passenger details with every airline and booking service you use. An old profile on a rarely used website can place the same error into a future reservation.

Frequently Asked Questions
Can you update your birthdate on an airline reservation?
Airlines and ticketing agencies can usually correct an incorrect birthdate for the same passenger. The available method depends on the airline, ticket issuer, route, and time remaining before departure. Some reservations allow online editing, while others require an agent.
What should you do if you need to correct your birthdate?
Compare the reservation with your passport or identification, identify who issued the ticket, and contact that company. Provide the booking reference and proof of the correct birthdate when requested. Review the updated confirmation afterward.
Who should you contact when a travel agency booked the flight?
Start with the travel agency or booking website that issued the ticket. The operating airline may be unable to change a ticket controlled by another company. Ask the ticket issuer to confirm the correction with every airline on the itinerary.
Can you fix your birthdate at airport check-in?
An airport agent may be able to help, but you should not depend on a last-minute correction. Ticket-control rules, partner airlines, document checks, or departure deadlines may limit what the airport can change. Contact the ticket issuer before travel whenever possible.
Will an airline charge a fee to correct a birthdate?
The answer depends on the airline and ticketing agency. A simple passenger-data correction may be free, but a service charge or ticket reissue may apply in some situations. Ask about the total cost before approving the change.
Does a wrong birthdate affect TSA PreCheck?
Incorrect or inconsistent passenger information can interfere with matching the reservation to a trusted-traveler profile. After the correction, confirm that the passenger’s name and Known Traveler Number remain accurate in the booking.
Do children need identification for a domestic flight?
TSA generally does not require children under 18 to show identification for domestic travel. The airline may still request a birth certificate or another document to confirm a child’s age, especially for infant or age-based ticketing rules.
Get It Right Before You Fly
Your date of birth is part of the passenger information used to process a flight reservation. A typo may be easy to correct when you find it early, but it becomes harder to resolve when the ticket came from another company, the itinerary includes partner airlines, or departure is close.
Check who issued the ticket, submit the correction with supporting identification, and inspect the updated reservation carefully. Confirming the details now can prevent check-in delays and reduce stress at the airport.
