I think the target user for sites like travelocity is probably fairly inflexible in their preferences. They want higher income, price insensitive business people who specifically want from point A to point B at time X. The sites and airlines don't really want to cater to College Kid Joe who's carefully weighing his options and playing around with them to save $150. Those people just don't drive revenue.
