tsa to be specific.
these pictures uploaded i think they will show, but not as well as the picture i tried to take, that it can be worth the small amount of time and money, if you fly enough, to warrant getting tsa precheck or global entry. if my information is still valid, the canadian system of nexus is really prime since it is cheaper and gets you global entry and precheck. but global entry i don’t think gets you nexus.
these pictures should show the ridiculously short tsa line. and at this airport i admit usually the precheck line is closed. maybe i’ve been taking the wrong flights. you can’t appreciate just how long the regular line extends back unless it’s clearer on a bigger screen.
