Hi, This is probably a rookie question, but was just looking for some clarity.

I used ExpertFlyer's Fare Information tool to look up a route I am planning to fly (YYZ to YVR) on a certain date. On my chosen date, there is a relatively cheap option, with a fare basis code of "AZ4NZCTG" - it is much cheaper than any flight I can find on the web (through AC, Kayak, etc.)

Is there any way to take advantage of this? How do I book a flight with this basis code and cost?

Thanks,
