What us a TSA Precheck?

A TSA PreCheck permits a number of low-risk travellers (and their children of 12 years and younger) to go through a more efficient and expedited screening process. The membership costs $85 USD and is valid for five years. Having a TSA PreCheck enables you to breeze through security for 56 airlines acrosss over 200 airports, with more being added to the scheme. The main reason people love using their TSA PreCheck is that airport wait time is 5 minutes or less 92% of the time. Plus, TSA Precheck members can keep liquids and laptops in their carry-on luggage and they do not have to remove the following items at security checkpoints:

  • Shoes
  • Belts
  • Light jackets

Who is eligible for TSA Precheck?

The TSA PreCheck program membership is only open to U.S. citizens and lawful permanent residents. If you're a US citizen and an active elite member of any of the partner airlines' Frequent Flyer Programs, you may be invited to opt-in for TSA PreCheck. If you choose to do so, you'll only be eligible to go through TSA PreCheck when you're flying on that FFP's airline.

In order to be eligible for TSA PreCheck for all airlines that allow for the service, you must have a 'known traveller number' (KTN). You must be travelling on an airline that accepts TSA PreCheck as well as an airport that accepts TSA PreCheck.

At Alternative Airlines, we only show passengers buying domestic flights in the US the option of adding their TSA PreCheck Known Traveler Number to their flight reservation. For those wishing to buy TSA PreCheck eligible flights from the US to international destinations, please contact Alternative Airlines and we can assist you with this request.

Which airports accept TSA PreCheck?

There are over 200 Airports that Accept TSA PreCheck across the entire United States. If you are not sure whether your local airport accepts TSA PreCheck, use the TSA PreCheck website to find out.

Can you use the TSA PreCheck lane when flying from a US airport to a foreign country?

TSA PreCheck is available when you depart from a U.S. airport to a foreign country, and for domestic, connecting flights after you return to the United States. If you travel to foreign countries even once a year, consider enrolling in Global Entry instead of TSA PreCheck. With Global Entry you’ll receive expedited customs processing when entering the United States, plus you’ll receive TSA PreCheck when flying from U.S. airports.

How do I apply for TSA PreCheck?

To apply for your TSA PreCheck membership, you first need to fill in an online application with your personal details. Ensure that the name that you write on this application form exactly matched the one on your passport and on the boarding pass you issue. Once you have applied online (the process takes around 5 minutes), you will be invited to a background check at your nearest enrollment centre. The in-person appointment usually takes no longer than 10 minutes. Find out where your nearest enrollment centre is located.

What is a TSA PreCheck number?

The number linked to TSA PreCheck is called a CBP PASSID and is given to you when you're approved for membership in Global Entry, NEXUS, or SENTRI. This is a nine-digit number that is also known as a known traveler number. Your known traveler number can be found on the back of your NEXUS, SENTRI, or Global Entry card. A known traveler number is a nine-digit number that can be used to verify that you're accepted to use TSA precheck when you make a flight reservation.

The TSA precheck number and NEXUS, SENTRI, or Global Entry card itself can not be used to access TSA PreCheck lanes, however, if you provide your TSA PreCheck to Alternative Airlines at the time of booking, we'll take care the rest and make sure that your known traveler number is linked to your flight and the TSA PreCheck indicator is embedded in the barcode of your boarding pass.
