I am going to Europe in December and would like to find P-class (deep discount business class) fares for the over the Atlantic segments. When I do a flight search and check what fares are available I can see "P9" for all the segments (the flights are wide open), but the website only offers me Z class fares or higher - which are more expensive than I want to pay.

Is there a way to get the website to offer me a P-class fare? Is there something I am missing? Will a call to a human help?

Thanks, Joe
