Rant mode ON because I see too many hunters unprepared, clueless and standing around with their thumbs up their asses waiting to get in the gun room: Get your ducks in a row. Get Global Entry, go with Delta custom comfort seats and get off the plane quicker, be first or second in line at the gun room, have your shoes ready to spray, out of your luggage or on your feet, have your passport and customs forms in your hand when you enter the gun room. Have your gun case lock keys in your hand, not in your pocket. Don't have more than one key for all locks. I've seen jackasses with four locks and two different keys fumbling to open their cases. In other words get your shit together BEFORE you leave the United States. Help YOURSELF, don't depend on someone else to worry about your connection. Rant mode OFF. I was there three weeks ago, I was done in a half hour and on my way to the gate to Philly and have made previous connections in less than a hour layover.
Aside from that, it's a hundred bucks for five years for Global Entry, another four hundred bucks for the Comfort seats. Average safari is 7k plus, the extra expense for the convenience is minimal in the overall cost. From this chai, trying to save what amounts to peanuts is just plain dumb.
