Check In Exactly 24 Hours Before

To further expedite the check-in process, consider joining TSA PreCheck. This program allows pre-approved travelers to go through a dedicated security screening line, where they can keep their shoes, belts, and light jackets on, and leave laptops and liquids in their bags.

This can save you a significant amount of time and stress at the airport.

Applying for TSA PreCheck is a simple process that involves filling out an application, undergoing a background check, and completing an in-person interview. The program is valid for five years and costs $85. It’s a small price to pay for the convenience and efficiency it provides.
