TSA will not let you through the security checkpoint without a boarding pass or other proof of a valid flight.

You need to show either a physical boarding pass, a mobile boarding pass on your phone, or a confirmation number that the TSA agent can look up in the airline system. The agent will scan or verify this before you enter the security line. Without one of these, you will be turned away at the checkpoint entrance.

The boarding pass serves as your ticket into the find area of the airport. It proves you have a seat on an actual flight departing that day. TSA agents check this at the start of screening, not at the end, so there is no way around it.

Key Takeaways

  • A boarding pass—physical, digital, or a confirmation number—is required before you enter the TSA security checkpoint.
  • You can obtain a boarding pass online, at an airline kiosk, or at the ticket counter up to 24 hours before your flight.
  • If you have lost your boarding pass, the TSA agent can look up your reservation using your confirmation number and ID.
  • Arriving at the airport without a boarding pass will delay you significantly, so print or read yours before you leave home.

How to Get a Boarding Pass Before the Airport

Most airlines allow you to check in online 24 hours before your flight. Go to the airline's website or app, enter your confirmation number and last name, and you will see an option to get your boarding pass. You can print it at home or save it to your phone as a mobile boarding pass.

A mobile boarding pass is a barcode on your phone screen that the TSA agent can scan. This is the fastest option because you do not have to print anything. Open your airline app, find your flight, and tap "Get Boarding Pass" or similar wording. The barcode will appear on your lock screen or in the app itself.

If you do not have access to a printer or prefer a physical copy, you can print your boarding pass at an airline kiosk in the airport terminal. These kiosks are usually near the ticket counter or entrance. You will need your confirmation number and ID.

What to Do If You Arrive Without a Boarding Pass

If you reach the airport without a boarding pass, go directly to the airline ticket counter before heading to TSA. Bring your ID and your confirmation number (found in your email confirmation or on the airline website). The agent will print a boarding pass for you on the spot.

This process usually takes 5 to 10 minutes, but it adds time to your airport arrival. If you are running late, this delay could cause you to miss your flight. For this reason, it is much better to print or read your boarding pass at home the night before.

Using Your Confirmation Number at the Checkpoint

If you have your confirmation number but no physical or mobile boarding pass, tell the TSA agent at the checkpoint entrance. Provide your ID and your confirmation number. The agent can look up your reservation in the airline system and verify that you have a valid flight.

This lookup takes a few extra minutes, and not all TSA checkpoints have the same speed or access to airline systems. You may be asked to step aside while the agent confirms your information. Having your boarding pass ready is always faster.

Boarding Pass Requirements for Different Situations

If you are traveling with a child, the child does not need their own boarding pass to enter the checkpoint with you, but you will need to show the agent that the child is on your reservation. Have your confirmation number ready so the agent can verify this.

If you are a standby passenger waiting for a seat on a later flight, you will not have a boarding pass yet. In this case, bring your ID and ask the airline agent at the ticket counter for a standby pass or a document that confirms your standby status. This document allows you to enter the checkpoint while you wait for a seat to open.

If you are traveling internationally, you will need your boarding pass and your passport. The boarding pass is still required at the TSA checkpoint, even though international flights have additional security steps.

Common Reasons Boarding Passes Get Lost or Forgotten

Many travelers print their boarding pass at home and then cannot find it in their bag at the airport. To avoid this, take a photo of your boarding pass on your phone as a backup. You can show this photo to the TSA agent if you lose the printed version, though a mobile boarding pass from your airline app is preferred.

If you checked in online but did not save your boarding pass, your confirmation email contains a link to retrieve it. Open your email on your phone and click the link to pull up your boarding pass again. This is why it is important to keep your confirmation email accessible during travel.

What Happens If You Try to Skip the Boarding Pass Check

TSA agents are trained to ask for your boarding pass before you enter the security line. If you do not have one and cannot produce a confirmation number, you will not be allowed through. You will have to leave the checkpoint, go to the ticket counter, and obtain a boarding pass before returning.

There is no way to bypass this step. The boarding pass is not just a TSA requirement—it is how the airline tracks who is on each flight and ensures the plane is not overbooked. Without it, you cannot board your flight even if you somehow made it through security.

Frequently Asked Questions

Can I use a screenshot of my boarding pass instead of the real one?

Yes. A screenshot of your mobile boarding pass works just as well as the original. The TSA agent will scan the barcode on your phone screen. Make sure the barcode is clear and not blurry when you show it to the agent.

What if my airline app is not working and I cannot pull up my boarding pass?

Go to the airline ticket counter and explain the situation. Bring your ID and confirmation number. The agent will print a boarding pass for you. This is why having your confirmation number written down or saved in a note on your phone is helpful.

Do I need a boarding pass to enter the airport terminal, or just to get through TSA?

You only need a boarding pass to enter the TSA security checkpoint. You can walk around the airport terminal without one. However, you cannot reach your gate or board your flight without showing a boarding pass at some point.

Can a family member pick up a boarding pass for me if I am running late?

No. The airline will only print or issue a boarding pass to the person whose name is on the reservation. Your family member can help you retrieve it online or via the airline app, but they cannot pick it up at the counter on your behalf.

What if I lost my ID and my boarding pass?

You will need to bring an alternative form of ID to the TSA checkpoint. Acceptable alternatives include a passport, military ID, or state ID. Once you show your ID, the TSA agent can look up your boarding pass using your confirmation number and last name.
