Priority Pass has introduced an app for the iPhone and iPad that provides photos of airport lounges and information about the lounge amenities such as free WiFi. Not all airport lounges are featured–only those accessible through a Priority Pass membership–but the free app is a good way to help you assess if a paid Priority Pass membership is something you want to sign up for. A standard pass is $99 per year, plus $27 per visit and other membership options are available.
