Reopening the T4-T5 tunnel is a back-to-the-future great idea. Other than for its obvious terminal and airline connectivity, I often enjoyed a nice, brisk, climate-controlled, stretch of the legs when my situation permitted.
I've always considered the tunnel system to be a genius, ahead-of-its time design gem of LAX. Even though very few people changed terminals when it was built, someone was thinking ahead.
