Thank you! I do not know if I need to go through

security if I do not go through the customs. This is what their website says:

Do I need to go through security to travel from one terminal to another?

A.If you are in the post-security checkpoint area, you can connect to any terminal without having to go in and out of security a second time. If you are walking to Terminal F from another terminal, or walking from Terminal F to another terminal, you must go through security to access post-security facilities. If you are post-security and wish to travel to and from Terminal F, there are free shuttle stops at Gate F-10, Gate C-16 (access to Terminals C,D,B) and Gate A-1 (access to Terminals A-East, A-West).

Do I need to go through security to reach my connecting flight after leaving the Customs area?

A.Yes, you will need to go through security to reach your connecting flight after leaving the Customs area. Return to Top
