Interesting idea, although I would imagine most customers buying an airline ticket would like to get to their destination quickly, hence the reason they bought a plane ticket in the first place, not a greyhound ticket. Imagine spending hundreds of dollars to find out you have to get shipped on a five hour bus ride to ORD before your flight even departs. On the other hand, maybe people living in EAS towns are used to long drive commutes to get to major cities anyways.
