Operating a major airline in the 1980s is essentially a(n)【69】of finding the right mix of passengers. The airlines need to fill up the back end of their wide-bodied jets with passengers paying a【70】fare, without forgetting that the front end should be filled with people who pay【71】more for their tickets.
It is no【72】that the two major airline bankruptcies in 1982 were among the companies【73】in cheap flights. But low fares require consistently full aircraft to make flights economically viable (可行的), and in the recent recession the【74】of traffic has not grown. Equally the large number of airlines jostling (争夺) for the【75】passengers has created a huge excess of capacity. The net result of excess capacity and cutthroat【76】driving down fares has been to push some airlines into【77】and leave many others hovering on the【78】.
Against this grim background,【79】is no surprise that airlines are【80】increasingly to the business travelers to improve their rates of return. They have【81】much time and effort to establish exactly what the executive demands for sitting apart from the tourists.
