There are several audiences for this question and at least as many possible answers. The audience which likely first comes to mind is the business person - finding his seat on an early Monday morning, then monitoring connection times as he makes his way home on Friday. Invisiblein that mental picture is a second audience: the traveler’s corporate travel policy. Then there is a third one – the corporate managers responsible for the execution and outcomes of that policy. It’s impossible for any travel agency to arrive at a good answer to the question unless it thinks in terms of managing travel rather than simply arranging travel.
