The Operation of International Airlines
International airlines have rediscovered (重新发现) the business traveler, the man or woman who regularly jets from country to country as part of the job. This does not necessarily mean that airlines ever abandoned their business travelers. Instead, companies like Lufthansa and Swissair would right argue that they have always catered best for the executive class passengers. But many airlines could be accused of concentrating too heavily in the recent past on attracting passengers by volume, often at the expense of the regular traveler. Too often, they have seemed geared for quantity rather than quality.
Operating a major airline is essentially a matter of finding the right mix of passengers. The airlines need to fill up the back end of their wide-bodied jets with low fare passengers, without forgetting that the front end should be filled with people who pay substantially more for their tickets. <
A. making their seats more comfortable.

C. showing more movies during the long flights.
D. offering sleeperettes to first-class passengers.
