Do I have to go through TSA again if I have a connecting flight?

How many times do you have to go through TSA on connecting flights? Most of the time on connecting domestic flights, you do not have to go through security a second time. As long as you do not leave the secure area you usually are ok.



In 2026, the answer depends on your origin and terminal layout. If you are on a Domestic-to-Domestic connection and stay within the "sterile" post-security area, you do not need to go through TSA again. However, if your connection requires changing terminals that are not connected airside, you must exit and re-clear security. For International-to-Domestic connections arriving in the U.S., you must clear Customs and Border Protection, collect your checked bags, and then go through TSA screening before your next flight. A key 2026 update: Beginning February 1, 2026, TSA strictly enforces REAL ID requirements; if you exit the secure area to change terminals and do not have a REAL ID-compliant license or passport, you may face a $45 noncompliance fee to re-enter.
