Can you add TSA PreCheck after check in?

Missed TSA PreCheck® on your boarding pass? Don’t panic just yet. While the ideal scenario is to add it during booking or before online check-in, there’s still a chance you can snag that expedited security lane even after you’ve checked in. Your success depends on your airline and their specific procedures.

Here’s the lowdown: Your boarding pass is your key. It needs to display the TSA PreCheck® indicator for you to use those designated lanes. So, if you’ve checked in and realized you forgot to add your Known Traveler Number (KTN), your best bet is to contact your airline directly.

Don’t rely on airport kiosks or TSA agents. Airlines control the boarding pass information, and they are the only ones who can update it with your KTN. Calling the airline is usually the quickest way to resolve the issue. Be prepared to provide your confirmation number and KTN.

The airline might be able to update your boarding pass electronically, sending you a new version via email or mobile app. In some cases, they might require you to visit the check-in counter at the airport to have a new boarding pass printed. This is why it’s crucial to contact them as soon as you realize the oversight, giving yourself ample time before your flight.

While there’s no guarantee the airline can add TSA PreCheck® after check-in, it’s certainly worth the effort. That extra time saved at security can make a significant difference, especially during peak travel periods. Remember, proactive communication with your airline is your best chance for a smoother, faster security experience.
