My first time flying out of Billy Bishop and so far it's been great! If you are flying to US you don't have to deal with customs till you arrive at your destination. They have complimentary coffee, tea, pop, water, and snacks! The snack bar at the gate is credit card only - no cash. But, they also have free charging/computer stations. A+
If you want more than a cookie buy your meal at the cafe where you wait for the free ferry to take over to the airport. Better selection! There are 2 small duty free shops at the gate.
