Operating a major airline in the 1980s 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.
It is no coincidence that the two major airline bankruptcies in 1982 were among the companies specializing in cheap flights. But low fares require consistently full aircraft to make flights economically viable, and in the recent recession the volume of traffic has not grown. Equally the large number of airlines jostling for the available passengers has created a huge excess of capacity. The net result of excess capacity and cut-throat competition driving down fare's has been to push some airlines into collapse and leave many others hovering on the brink.
Against this grim background, it is no surprise that airlines are turning increasingly towards the business travelers to improve their rates of return. They have invested much time and effort to establish exactly what the executive demands for sitting apart from the tourists.
High on the list of priorities is punctuality; an executive's time is money. In-flight service is another area where the airlines are jostling for the executive's attention. The free drinks and headsets and better food are all part of the lure.
One criticism against many international airlines is that they have, in the recent past, ______.
A．catered for the more wealthy people
B．given preferential treatment to executive clients
C．only met the needs of the regular travelers
D．marketed their service with the masses in mind

Teachers are grateful, but know it may be years before the district is solvent(有偿付能力的). They feel really good about the parent support, but they realize it's impossible for them to solve this problem.
The 22,000-student district discovered the shortage last month. "It's extraordinary. Nobody would have imagined something happening like this at this level," said State Treasurer Mike Coffman.
Coffman and district officials last week agreed on a state emergency plan freeing up a $ 9.8 million loan that enabled the payroll(工资单)to be met for 2,700 teachers and staff in time for the holidays.
District officials also took $1.7 million from student-activity accounts in its 38 schools.
At Coffman's request, the District Attorney has begun investigating the district's finances. Coffman says he wants to know whether district officials hid the budget shortage until after the November election, when voters approved a $ 212 million bond issue for schools.
In Frederick, students' parents are buying classroom supplies and offering to pay for groceries and utilities to keep first-year teachers and principals in their jobs.
Some $ 36,000 has been raised in donations from Safeway. A Chevrolet dealership donated $10,000 and forgave the district's $10,750 bill for renting the driver educating cars. IBM contributed 4,500 packs of paper.
"We employ thousands of people in this community," said Mitch Carson, a hospital chief executive, who helped raise funds. "We have children in the school, and we see how they could be affected."
At Creek High School, three students started a website that displays newspaper articles, district information and an email forum(论坛). "Rumors about what's happening to the district are moving at lighting speed," said a student. "We wanted to know the truth, and spread that around instead."
