For many executives, flying business class is both the comfortable choice and the financially smart one. However, there are some cases where buying a more expensive business class ticket could be unwise. Avoid paying for business class on short domestic flights, where gains from productivity are marginal. Instead, fly business class on long-range flights where 8-16 hours could be spent working in comfortable quarters instead of a cramped seat. Try to leverage frequently flyer programs into upgrading a coach ticket to business class. This is one of the few ways that businesses can get discounted tickets, as airlines customarily charge full-price for their business class tickets.
