What if I forgot to add TSA PreCheck?

TSA PreCheck: Oops, I Forgot! Now What?

So you’re heading to the airport, boarding pass in hand, and suddenly a cold dread washes over you: you forgot to add your TSA PreCheck information to your flight reservation. Panic sets in – will you be stuck in a long security line? The answer is a reassuring “probably not,” but it depends on the timing.

While adding your TSA PreCheck number before you arrive at the airport is ideal for a smooth and speedy experience, forgetting doesn’t automatically doom you to a security line marathon. The key is to understand your options and act quickly.

What to do if you forgot BEFORE you arrive at the airport:

• Update your airline profile: This is the easiest and most effective method. Most major airlines allow you to update your frequent flyer profile with your TSA PreCheck Known Traveler Number (KTN) even after booking your flight. Log into your account on the airline’s website or app, find your passenger profile, and add your KTN to your information. It usually takes a short time to update, but it’s best to do this well in advance of your departure. Check the airline’s website for specific instructions as the process may vary.

• Contact your airline: If you’re having trouble updating your profile online or are short on time, call your airline’s customer service. They may be able to add your KTN to your reservation manually. Be prepared to provide your booking reference number and KTN.

What to do if you forgot AFTER you arrive at the airport:

Your chances of utilizing TSA PreCheck after arriving at the airport are significantly reduced. The system is largely automated and updates may not be instantaneous.

• Check your boarding pass: Some airlines may automatically include your TSA PreCheck status on your boarding pass, even if you added it recently. Double-check your boarding pass and the security checkpoint signage.

• Try your luck: While unlikely, you might still be able to get through the PreCheck line if the airline system updated before you reached security. It’s a long shot, but it’s worth trying.

• Prepare for a regular security line: Be prepared to go through the standard security line if your PreCheck information didn’t update in time. Allow extra time to account for potential delays.

Prevention is key: The best way to avoid this situation is to add your TSA PreCheck KTN to your airline profile before you book your flight or immediately after. Make a note of it in your travel documents, and even set a reminder on your phone or calendar.

In short, forgetting your TSA PreCheck information isn’t a disaster. While there’s no guarantee of accessing the PreCheck lane if you add your KTN late, updating your airline profile is your best bet for a less stressful airport experience. Acting quickly and being prepared for both outcomes will significantly alleviate any anxiety.
