Discount Airfare Search

[B Sousa]

Finding a reasonable airfare can sometime be a real pain. I have found that by searching the internet, I can usually get something I can live with. Problem is all this seems to be directed towards Economy. Also most sites ask you for specific dates. Im very flexible and could take a bigger window for a better price. Are there some sites out there where one can search for a discounted Business or First Class Ticket and variable dates??

Thanks
