The Transportation Security Administration (TSA) announced the expansion of its TSA PreCheck program with the addition of Aer Lingus, Air New Zealand, Ethiopian Airlines and Saudia. Nearly 100 airlines now participate in the program.

PreCheck is an expedited screening program enabling low-risk travelers to enjoy a secure and efficient screening experience at more than 200 US state and territory airports, and one foreign preclearance airport at the Lynden Pindling International Airport in Nassau, Bahamas.

Passengers using PreCheck may keep on their shoes, belts and light jackets and are not required to remove laptops, 3-1-1 liquids and food items from their carry-on bags. About 99% of TSA PreCheck passengers wait less than 10 minutes in dedicated lanes at airport checkpoints nationwide, according to the agency.

The program is available for eligible passengers departing from a participating airport or connecting on domestic flights after returning to the US from a foreign airport. Travelers who are US citizens, US nationals or US lawful permanent residents may apply for TSA PreCheck and can pick any enrollment provider based on cost, location and additional benefits. Costs for enrollment vary by provider.

PreCheck is continually expanding its list of participating carriers, especially in recent months. In March, TSA added eight new airlines to the program, including Air Premia, Air Tahiti Nui, Air Transat, Bahamasair, BermudAir, Iberia, La Compagnie and New Pacific Airlines.

Teenagers aged 13-17 may now accompany TSA PreCheck enrolled parents or guardians through TSA PreCheck screening when traveling on the same reservation and when the TSA PreCheck indicator appears on the teen’s boarding pass. Children 12 and under may accompany an enrolled parent or guardian in the TSA PreCheck lanes without restriction.
