TSA PreCheck: Is It Worth It, and How Do You Apply?

TSA PreCheck is one of the few travel upgrades that genuinely saves time on nearly every domestic trip, not just occasionally. Here's what it actually gets you.

What TSA PreCheck actually changes

With PreCheck, you generally keep your shoes, belt, and light jacket on, leave laptops and approved liquids in your bag, and go through a dedicated, usually much shorter security lane at participating US airports. It doesn't change anything about check-in, baggage, or boarding — it's specifically a security-screening benefit.

How to apply

1. Apply online through the TSA's official application system and pay the application fee.
2. Schedule an in-person appointment at an enrollment center for identity verification and fingerprinting — many are located in airports and other convenient locations.
3. Receive your Known Traveler Number (KTN) after approval, typically within a few days, and add it to your airline profile and every future booking.

What it costs

TSA PreCheck carries a flat application fee for a multi-year membership (check the TSA's official site for the current fee, since it can change). Many premium credit cards reimburse this fee as a cardholder benefit — worth checking before you pay out of pocket, since it can effectively make PreCheck free.

Is it worth it for you?

• Worth it if you fly domestically more than a couple of times a year, especially through busy hub airports where standard security lines run long.
• Less essential if you fly only rarely, or your home airport's regular security line is already fast.
• Pairs well with Global Entry, a separate (slightly pricier) program that includes PreCheck plus expedited US customs re-entry for international travel — worth comparing if you also travel internationally.

Using your Known Traveler Number

Add your KTN to your airline's frequent flyer profile once, and it should populate automatically on future bookings made under that profile. If you book by phone, give your KTN to the agent at the time of booking so it prints correctly on your boarding pass.

Frequently Asked Questions

How long does TSA PreCheck last?

Membership is valid for several years from approval (check the TSA's current terms), after which you renew, usually through a simpler process than the initial application.

Does TSA PreCheck work at every airport?

It's available at the large majority of US airports and with most major airlines, but not literally every airport or flight has a PreCheck lane — check availability for your specific departure airport if it matters to your trip.

Is Global Entry better than TSA PreCheck?

Global Entry includes PreCheck benefits plus expedited customs processing when re-entering the US from international travel, for a somewhat higher fee. If you travel internationally at all, Global Entry is usually the better value.

Can my credit card pay for TSA PreCheck?

Many travel and premium credit cards offer an application fee credit or reimbursement for TSA PreCheck or Global Entry as a cardholder perk — check your card's benefits before paying the fee directly.
