Where is the Kayak flight booking through (i.e. United.com, Orbitz, etc.)? Most booking channels allow you to look at the fare rules before purchasing the ticket, and this will show you the fare basis. The first letter is almost always the booking code.
It's through Orbitz, but I don't see a way on how to find out the fare rules.
