We are planning our first trip to CN soon (May) and I have never flown before, ever, my husband has once or twice. This may be a silly question,But we were wondering if we pay off our trip and then fuel costs or something else goes up, will we be asked to pay more or will the original amount that we paid stay the same? And are there any hidden fees once you get to the airport besides maybe baggage fees?

And also, we were wondering what is the best way to book a trip to Dunn's River, at the resort or online before we go?
