For travelers with TSA PreCheck in 2026, the recommended arrival time is generally 60 to 90 minutes before a domestic flight and 2 to 2.5 hours before an international flight. While the standard "2-hour rule" for domestic travel provides a safe cushion for the general public, PreCheck significantly streamlines the process by allowing you to keep your shoes, belt, and light jacket on, and leave your laptop and 3-1-1 liquids in your bag. On average, PreCheck lines move in under 10 minutes, even during busy periods. However, "PreCheck" only saves you time at the security checkpoint; you still must account for the time needed to park your car, check your bags (which can take 20–30 minutes at a busy hub like ATL or LAX), and navigate the airport to your gate, which may be a 15-minute walk or train ride away. If you are not checking bags and have your boarding pass on your phone, you can often push your arrival to the 60-minute mark. For international travel, the extra hour is essential because airlines must perform manual passport and visa verifications at the counter or gate, which can create bottlenecks that "expedited security" cannot bypass.
