How to sign up for TSA PreCheck Touchless ID and save time at airports

As TSA lines grow longer at U.S. airports, travelers can speed up security checks by enrolling in the TSA PreCheck Touchless ID program. This program uses facial recognition technology for quicker identity verification and is available at 65 airports. To join, travelers must have TSA PreCheck, a frequent flyer profile with a participating airline, and valid passport information uploaded. Currently, five airlines—Alaska, American, Delta, Southwest, and United—offer this program, each with its own enrollment process. For example, Alaska Airlines requires an Atmost Rewards account, while American Airlines needs an AAadvantage account. Delta uses SkyMiles accounts, and Southwest requires a Rapid Rewards account. This program aims to make airport security more efficient and less time-consuming for travelers.
