On a recent trip EWR-PHX-IAH-PVR-ZLO-IAH-PHX-EWR, I didn't bother to take out my One Pass card, just showed my BP which clearly said "Platinum / Sky Team Elite Plus" and said "this is my companion" they typed something and said the Matron "enjoy your stay"

Both times at IAH, 9/2 @ Terminal E (out bound) and then 9/5 @ Termincal C President's Club South (inbound).

One minor issues was on the inbound, the Matron was confused at why I was asking for entry,t hen I explain "Elite Plus on an International Intn" and she was "oooo you are right - sorry"
