How to Change Date of Birth on Delta Ticket (2026): Fees, Policy &Steps

Booking a flight is usually a quick process — until you realize later that one small detail is wrong. A date of birth entered incorrectly on a Delta ticket is more serious than a typo in a middle name, because it directly affects the Secure Flight Passenger Data that the TSA requires airlines to submit before a passenger boards. If your date of birth on a Delta ticket doesn't match your government-issued ID, you may be flagged at security or denied boarding entirely.

The good news is that Delta does allow passengers to correct a wrong date of birth before travel, and knowing the right process — and the right timing — makes the difference between a smooth fix and a stressful experience at the airport.

This guide walks through everything: why the date of birth matters so much, how to update it, what the process looks like in different situations, and what to do if you're close to your departure date.

Why a Wrong Date of Birth on a Delta Ticket Is More Serious Than It Looks

When you book a flight on Delta, the airline collects what's called Secure Flight Passenger Data — your full legal name, date of birth, and gender. This information is submitted to the TSA before your flight departs, and the TSA cross-references it against government watch lists and identity records. If your delta ticket date of birth correction doesn't happen before the data is submitted, you may be flagged for additional screening or, in some cases, prevented from boarding.

This is fundamentally different from a small name spelling correction. A difference of one digit in a date of birth — for example, entering January 3rd instead of January 13th — can create a mismatch that shows up as a potential identity discrepancy at the security checkpoint. If you also have a name spelled incorrectly on your ticket, that's a separate issue that needs its own correction — you can find the full process in the Delta name correction guide Airlines take TSA Secure Flight requirements seriously, and so should passengers.

Consider this scenario: Ramona booked a flight from Los Angeles to New York for a work conference. In the rush of booking, she entered her birth year as 1989 instead of 1986. She didn't notice until she checked her confirmation email three days later. Because she caught it early, she was able to call Delta and have the date corrected before the Secure Flight data was submitted — and she boarded without issue. Had she noticed at the airport instead, the outcome could have been very different.

The earlier a delta wrong date of birth ticket issue is caught and corrected, the simpler the fix. That's the single most important thing to take from this section.

The Difference Between a Minor DOB Typo and a Major Data Error

Not all date of birth errors on a Delta ticket are equal, and understanding the distinction helps you approach the correction with the right expectations.

A minor DOB typo is typically a single-digit transposition — a passenger who was born on May 7 and accidentally entered May 17, or someone who typed 1994 instead of 1994 in the day field and ended up with a one-digit error. These are honest keyboard mistakes, and Delta's customer service team generally treats them as straightforward corrections when caught early and when the passenger's identity can be verified.

A major data discrepancy is a situation where the date of birth entered is significantly different from the actual date — for example, a different year entirely, or a month and day combination that bears no resemblance to the correct one. These corrections require more verification because they look more like potential booking errors or identity issues, and Delta may ask for additional documentation.

There is also a third category that occasionally comes up: the wrong passenger's date of birth entirely. This happens when someone books tickets for multiple family members and enters dates of birth in the wrong fields. In this case, the issue isn't a typo — it's a data entry mix-up across passengers. Delta treats these differently depending on whether the ticket has been ticketed and whether travel is domestic or international.

Accurate birth date information is especially important for children and teenagers traveling with Delta, as age determines eligibility for infant fares, child seating requirements, and unaccompanied minor services.

How to Change Date of Birth on a Delta Ticket — The Right Way to Start

The first step when you discover a delta wrong dob fix is needed is to not panic — but also to not wait. Here's how to approach it based on how you originally booked.

If you booked directly through Delta (delta.com or the Fly Delta app):

Log into your Delta account and go to "My Trips." Select the booking in question. In some cases, Delta allows passengers to edit Secure Flight Passenger Data — including date of birth — directly through the manage booking interface. If the option to edit is available and your travel is more than 72 hours away, use it. Make the correction, save it, and take a screenshot of the updated confirmation showing the correct DOB.

If the online edit option is not available or is greyed out, do not try to work around it — proceed directly to calling Delta's customer service line. This happens when the ticket has already been ticketed at a fare level that locks certain fields, or when the departure is within a window that requires agent assistance.

If you booked through a third-party travel site or agency: This is where many passengers get stuck. If your ticket was issued through Expedia, Kayak, a travel agent, or another third-party platform, Delta's own systems may not allow you to make the correction directly — you'll need to go through the original booking source first. Contact the third-party platform, explain the DOB error, and ask them to submit a correction request to Delta on your behalf. Then follow up with Delta directly to confirm the update was applied.

If you're calling Delta directly: Call Delta's reservations and customer service line. Have your booking confirmation number, the correct date of birth, and a copy of your government-issued ID or passport ready. The agent will verify your identity, look up the booking, and process the delta correct date of birth ticket update. In most cases, a DOB correction on a domestic ticket does not require a fee — it's treated as a data correction rather than a ticket change. However, this can vary depending on the fare type and timing.

Correcting a Date of Birth During the Online Check-In Window

Delta opens online check-in 24 hours before departure. If you're trying to correct a delta edit date of birth booking error during this window, the situation is time-sensitive and requires immediate action.

During check-in, Delta's system prompts passengers to confirm their Secure Flight Passenger Data. If you notice a wrong date of birth at this stage, do not complete check-in with the incorrect information. Completing check-in locks in the data that Delta submits to the TSA. Instead, exit the check-in process and call Delta's priority line immediately.

Here's a scenario that illustrates this well: David was checking in online for his flight from Denver to Miami the evening before departure. He noticed his birth year was listed as 1991 instead of 1981 — a ten-year difference. He called Delta's customer service immediately, explained the situation, and an agent corrected the DOB in the booking. David then completed check-in after the correction was confirmed and boarded without any issues. The key was catching it before submitting the check-in form.

If you're within the 24-hour check-in window and your departure is in fewer than three hours, go directly to the airport. Speak with a Delta agent at the ticketing counter — not the check-in kiosk. Airport agents have the ability to make corrections that cannot be processed online or over the phone at that point. If a last-minute DOB issue forces you to miss your original flight, you'll want to understand your rebooking options right away — the Delta Airlines same day flight change policy explains what's possible and whether fees apply based on your ticket type.

What Documentation Delta May Ask You to Provide

When you request a delta ticket date of birth correction, Delta's ability to make the change quickly depends partly on what documentation you can provide. For most domestic flights with a straightforward single-digit error, a verbal confirmation and your booking details may be sufficient for the agent to process the correction.

For corrections that involve a more significant discrepancy — a different year, a transposed month, or a date that doesn't resemble the correct one — Delta may ask you to verify your identity with documentation. This can include a passport, driver's license, birth certificate, or government-issued national ID. Having these ready when you call speeds the process considerably.

For international flights, documentation is almost always required for a date of birth correction, because the DOB on your ticket must match your passport exactly for immigration purposes. If you're flying internationally and discover a delta wrong date of birth ticket error, treat it as urgent regardless of how far in the future your travel is. International corrections can sometimes take longer to process and may need to be coordinated with destination country requirements.

A note on children's tickets: parents frequently book tickets for their children and occasionally enter a sibling's or the wrong child's date of birth by mistake. Delta asks for a copy of the child's birth certificate or passport in these situations to confirm the correct information before updating the record. Parents booking tickets for children traveling without them should also be aware that Delta has specific requirements around age, supervision, and documentation — all covered in the Delta unaccompanied minor policy guide.

The Connection Between Date of Birth and Delta's Secure Flight Passenger Data

Delta, like all U.S. airlines, is required by the TSA to collect and submit Secure Flight Passenger Data for every passenger before the aircraft departs. This program — administered under federal aviation security regulations — requires the following fields to be accurate: full legal name (matching your ID), date of birth, and gender.

The reason delta passenger information change policy treats DOB corrections with particular care is that this data is what the TSA uses to clear passengers before boarding. A mismatch between your ticket and your ID doesn't just create a paperwork problem — it can result in being marked for enhanced screening, which means longer security lines, additional checks, and potential delays that affect not just you but your travel companions.

For passengers who have TSA PreCheck or Known Traveler Numbers, an incorrect DOB on the ticket can also temporarily deactivate your PreCheck eligibility for that specific flight. If your Known Traveler Number is associated with your correct DOB in the TSA system but your Delta ticket has a different DOB, the system may not be able to verify the match — and you could end up in the standard security line instead of the expedited one.

This is particularly relevant for frequent flyers who book quickly and rarely review their confirmation details. Delta's delta secure flight passenger data correction process exists precisely for these situations — and using it proactively, before you're standing at a security checkpoint explaining a discrepancy, is always the right move.

Delta's Name and DOB Correction Policy — What's Covered and What Isn't

Delta's name and dob correction policy draws an important distinction between corrections and changes. A correction is fixing data that was entered incorrectly at the time of booking — for example, transposing digits in a birth year, or entering the wrong day. A change is altering the booking to reflect different passenger information that wasn't an entry error — for example, transferring a ticket to a different person.

Delta does not allow ticket transfers to different passengers, so if the date of birth entered belongs to a completely different person, Delta may require rebooking rather than a correction. This is an important distinction because it affects whether you pay a fee. Along with ensuring correct passenger details like date of birth, travelers should also review Delta Airlines baggage policy, including carry-on size limits, checked baggage costs, and weight restrictions before flying.

For legitimate corrections — errors that occurred at the time of booking — Delta generally processes the update without a rebooking fee, though this can depend on the fare class. Main Cabin and higher fares are typically handled as administrative corrections. Basic Economy fares, which are more restrictive in general, may have limited flexibility depending on the nature of the error. If a DOB error forces you to cancel and rebook an entirely new ticket, understanding what refund or credit you're entitled to becomes essential — the Delta cancellation policy explains exactly what applies by fare type.

What delta passenger information change policy does not permit: changing passenger information in a way that amounts to giving the ticket to someone else, changing the DOB repeatedly on the same booking, or making corrections after check-in has been completed and Secure Flight data has already been submitted to the TSA.

When to Call Delta vs. When to Go to the Airport

One of the most common questions passengers have after discovering a delta correct passenger details dob issue is whether they should handle it on the phone or in person. The answer depends on your timeline and the complexity of the error.

Call Delta customer service when: You have more than 24 hours before your departure and the correction is a straightforward single-field error. Phone agents have full access to booking records and can process most DOB corrections without escalation. Have your confirmation number, correct date of birth, and photo ID information ready before the call.

Go to the airport ticketing counter when: Your flight departs within a few hours and you've been unable to resolve the issue by phone. Airport ticketing agents can make corrections directly in the system and also communicate with gate agents if needed. This is the fastest path when time is critically short.

Go through the third-party platform first when: You booked through an external site. Calling Delta directly in this case may result in the agent telling you they can't modify a third-party booking — which is technically correct. Start with the platform, then follow up with Delta to confirm the change was applied.

Think of it this way: Stephanie booked her family's vacation to Florida through a discount travel website. A week before the trip, she noticed her daughter's DOB was entered as 2014 instead of 2016. She contacted the travel site first, who submitted the correction to Delta within 48 hours. Stephanie then called Delta to verify the update was showing correctly in their system. By the time they arrived at the airport, everything was aligned and the family boarded without any issues.

Steps to Take Right Now If Your Delta Date of Birth Is Wrong

If you've just discovered a delta update date of birth issue on your booking, here's exactly what to do, in order:

Start by pulling up your full booking confirmation from Delta — either from the Fly Delta app or your confirmation email. Look specifically at the Secure Flight Passenger Data section, which typically shows the name, date of birth, and gender on file. Compare this to your actual date of birth on your driver's license or passport.

If you find a discrepancy, check how you booked. If it was directly through Delta, log into your account and try the edit function in My Trips. If the edit is unavailable, call Delta immediately. If you booked through a third party, contact that platform first.

When you speak to an agent — whether at Delta or a third-party platform — state clearly that you're requesting a date of birth correction for Secure Flight Passenger Data purposes. Using this specific language helps the agent understand the urgency and route the request correctly.

After the correction is made, ask for an updated confirmation or a written acknowledgment that the DOB was changed in the system. Screenshot it and keep it accessible on your phone until after you've boarded.

Finally, when you go through security, carry your government-issued ID that shows the corrected date of birth. If a TSA agent raises any questions, being able to show the corrected confirmation alongside your ID gives you the best position to resolve it quickly. While you're reviewing your booking details before travel, it's also a good moment to confirm your baggage allowance and check-in rules are in order — the Delta checked baggage policy guide covers carry-on sizes, checked bag fees, and what to expect at the counter.

Preventing a Wrong Date of Birth at Booking — What to Do Before You Click Confirm

The best delta wrong date of birth ticket fix is the one you never need. Most DOB errors happen for the same handful of reasons: booking too quickly without reviewing, autofill entering outdated or incorrect information, or booking multiple passengers and selecting fields in the wrong order.

A few habits that prevent these errors before they happen: always review the Secure Flight Passenger Data section of your booking before finalizing payment. Delta displays this information on the payment confirmation screen — take 20 seconds to verify the date of birth before submitting. If you're booking for multiple passengers, verify each person's DOB separately rather than scrolling through all of them at once. This is especially important when booking for very young children — parents traveling with infants should also verify that the infant's age-related fare and travel rules are correctly applied at booking, which the Delta Airlines infant bassinet policy explains in full detail.

If you use autofill in your browser or travel apps, check periodically that the saved profile information is accurate. A profile that was set up years ago and never updated may have stale information — including an old address, but also potentially an incorrectly saved date of birth.

After booking, open the confirmation email and check the Secure Flight data again. This takes less than a minute and is the last line of defense before you'd need to go through the correction process. Delta sends a full confirmation with all passenger details — it's worth the 60 seconds to review it before closing the tab.

Catching a delta change dob on ticket issue immediately after booking is always better than catching it at the airport. The sooner you act, the more options you have — and the simpler the fix.
