Thanks guys for addressing everything. The only thing I still have questions about is how to check the different fare classes. When I do the search on AA it comes up with all of the options and I click on details and I can see what the price is for the ticket that is being quoted. But if it shows $X for a Y ticket, I don't know how to find out what the price is for a B ticket because that option isn't showing. And maybe that's because there's no availability. Am I to assume that AA will quote the cheapest price for each ticket tier?
