If your flying EK or EY in Business for First, your almost always away from the regular Crowd, not that you have too, but you can walk fast from the Business or First class lounge to the Gate. I've been to AUH in F and no problems I have had my own space always, my Tefilin passed through the security xray machines and no questions asked, the staff\crew are mostly internationals both in the Lounges and on the Aircraft.
