"According to an April 2003 report from the Alexandria, Va.-based National Business Travel Association, less than 5% of business travelers fly first and business class, while more than 70% fly in restricted economy. But this tiny group is contributing to the majority of the airline's revenue. "These premium seats can account for 40% to 60% of the revenue, while they're practically giving away seats in the back," says Bennett."
I wondered for a long time if there was a case for a purely business and first class airline or is one already in existence?
