A plan for business travellers to fly economy. But will it take off?
Chad Lykins says firms can donate the savings to charity, to do some good

Want to stump your friends at the next party? Ask them this: Where is the most expensive office space in the world?
Hong Kong? New York? London? The answer is none of the above. Or actually, above all of them. You'll have to look up for the answer - it's the extra foot you get when you fly business class.
On a typical flight from Hong Kong to Tokyo, you will pay HK$16,600 more than economy class for the privilege of renting that extra foot of space for five hours or so. The price of fuel, maintenance and other incidentals is already covered by the economy airfare.
Considered annually, the extra foot of office space in business class costs over HK$2 million per month, compared to HK$138 per square foot in Two IFC.
Why do corporations still fly their people business class? There are a couple of reasons. First, most businesses do not do it that often, and when they do, they perceive it to be a necessity. Second, they often do it as part of an effort to take better care of travel-weary employees.
That is why most large companies have travel policies that permit business class on flights over a certain length. They are generally good policies.
However, not all employees are the same. Some would be happy to fly economy class every once in a while - if they felt like it produced some good.
