These Four International Airlines Are TSA PreCheck's Latest Additions

TSA PreCheck is arguably one of the best things to happen to airports, and for travelers flying internationally, it just got even better. In July 2024, the Transportation Security Administration announced that four airlines have joined the TSA PreCheck program. The new additions include Ireland's Aer Lingus, Air New Zealand, Ethiopian Airlines, and Saudi Arabia-based carrier Saudia. Now, Precheck-approved passengers flying with these airlines can enjoy speedy security lines, where shoes don't have to be removed, and electronics and liquids can stay inside carry-on bags.

Keep in mind that the airport security scheme is still only available at U.S. airports. If you're departing from an international airport, you won't be able to use TSA PreCheck to bypass the regular security line, even if you're flying into the U.S. with a participating airline. Additionally, the requirements needed to apply for TSA PreCheck remain the same: You must be a U.S. citizen, national, or lawful permanent resident believed to pose no threat to aviation security.

This isn't the first time TSA PreCheck has expanded its list of participating airlines. In August 2023, a handful of other international airlines joined TSA PreCheck, including Cayman Airways, French Bee, Titan Airways, and Zipair. A whopping eight international airlines — Air Premia, Air Tahiti Nui, Air Transat, Bahamasair, BermudAir, Iberia, La Compagnie, and New Pacific Airlines — were also added in early 2024, before July's newcomers.

At the time of writing, nearly 100 airlines are compatible with TSA PreCheck's security procedures. All major U.S. carriers, including Delta, American Airlines, Southwest Airlines, and United, are on the list. Many of the world's biggest international airlines also participate in the TSA PreCheck program, including famous names like KLM and Air France. Still, some well-known carriers are notably absent, such as Ryanair and easyJet.

However, don't be surprised if you see some familiar favorites added to TSA's lineup soon. In 2023, the security agency confirmed that membership in its PreCheck program had reached an all-time high, with 15 million active members. As more travelers sign up and use the TSA PreCheck lane, you might see more airlines jumping on board.

A complete, up-to-date list of participating airlines can be found on the TSA website. Keep in mind that the carriers registered are subject to change. If your airline doesn't currently participate, you won't be able to use TSA PreCheck, even if you're enrolled in the program and provided a Known Traveler Number (KTN) on your flight reservation.

Besides consulting TSA's website before your trip, you can also check your boarding pass to confirm that your flight is eligible for PreCheck screening. If TSA PreCheck doesn't show up on your boarding pass — and assuming your membership is still valid — your airline may not subscribe to the program. Although it can be frustrating to pay for expedited security screenings and not have access to them for every flight, the best thing to do in these cases is to accept your fate in the regular security line. You can also contact your preferred airline and ask them to consider joining TSA PreCheck to improve your future travel experience.
