Unfamiliar with the Priority Pass? It is a pass that gets you access to almost 1,000 executive clubs around the world.
Sitting in an airport for hour can be fun but sitting in the executive club for hours until your next flight is more fun and much more relaxing and civilized. You get to access the food and drink in these clubs while waiting for your flight and also get access to the usually free wifi in the club.
Note: Access to the Priority Pass clubs is restricted so if you are in uniform you cannot access the clubs. Only when traveling on vacation.
