Escorts are not provided by TSA
Passengers are allowed to leave the airport and re-enter through security. However, it is important to leave enough time to get back through security. In some cases, passengers may need to be escorted by staff to immigration and have their boarding pass "released" on the security system.

For example, Air France provides an escort to first-class passengers, helping them cut the line. In contrast, Korean Air does not provide escorts through security due to TSA regulations. Lufthansa is known for providing escorts to first-class passengers, but even their policy varies based on the airport.
The Airport Escort Screening Courtesies Program, administered by the Office of the Chief of Protocol, is available for foreign officials equivalent to members of the US Cabinet and their families. Requests for this program must be submitted three business days in advance, and late submissions may not be approved.
