What does it mean to say that Delta airlines “can’t validate your ticket?” 

Why Can't Delta Validate My Ticket? on a delta background

You’re on your Delta app the day before your flight, and you can actually see your reservation with your flight and seat information, but when you press the button to check in, you receive an error message through the app. You get your laptop out, and try again through Delta.com.

Again: “We’re sorry. We can’t validate your ticket. Please contact your local reservation office,” and another one, “You don’t have an electronic ticket. Please check with an agent.” You call and text and are still awaiting a response. You wonder if this is something you can take care of at the airport tomorrow. 

Unfortunately, these sorts of things happen occasionally (it’s just part of traveling), but it can be so frustrating when technology can’t deliver what we need when we need it. I will answer questions about what this means if it happens and what you can do about it to resolve the situation, along with other related questions I’ve heard from readers.

Why Can’t Delta Validate My Ticket?

Delta is likely unable to validate your ticket because there is an issue with the information provided or the ticket itself. Some common reasons why a ticket may not be valid include:

  • The ticket has already been used or has expired
  • The ticket was not purchased from a authorized agent or source
  • The information on the ticket, such as the passenger’s name or flight details, does not match the information on file with Delta
  • The ticket has been canceled or refunded
  • The ticket is a duplicate or has been reported as lost or stolen
  • The flight information has been changed, but the ticket has not been reissued

You’ll likely have to contact Delta directly at: (800) 221-1212 for further assistance and to verify that your reservation is valid before attempting to check in online. They can at least tell you what you need to do or with whom you need to speak to resolve the issue.

How Are Tickets Verified at the Airport?

Ticket verification involves several steps to ensure the ticket is genuine and belongs to the correct passenger when you arrive at the airport. The authenticity of tickets is verified by airlines using advanced security measures. The validity of a ticket can be confirmed by scanning a barcode or QR code on the ticket, for example. As well as facial recognition technology, airlines may also use biometrics to verify passengers’ identities.

The ticket verification process is designed to ensure that only authorized passengers are allowed to board flights and that all passengers are on the correct flight.

In 2018, a total of 813.8 million (813,791,287) passengers and crew members passed through TSA screening. With that many people, it’s no wonder that the TSA has adopted a “no questions asked” policy.

Here are the typical steps that occur during the ticket verification process:

Check-in: The first step is to check-in for your flight. This is typically done at a check-in counter or self-service kiosk. During check-in, you will be asked to provide your ticket and identification.

Security check: After check-in, you will need to go through security. You must present your ticket and identification again, along with any carry-on luggage or personal items for inspection.

Boarding pass: Once you have passed security, you will receive a boarding pass. This document contains information about your flight, including your seat number, departure gate, and boarding time.

Boarding: When it is time to board your flight, you must present your boarding pass and identification again at the gate. The gate agent will scan your boarding pass to confirm that it is valid and belongs to the correct passenger.

Boarding verification: Prior to boarding, a flight attendant will check your boarding pass to ensure it matches your identification and that you are on the correct flight.

In-flight verification: During the flight, the flight attendants will make several announcements reminding passengers to check their boarding passes to ensure they are on the correct flight.
