Question ID:PT9 S4 Q3 Passage:It might seem that an airline could increase profits by reducing airfares on all its flights in order to encourage discretionary travel and thus fill planes. Offers of across-the-board discount fares have, indeed, resulted in the sale of large numbers of reduced-price tickets. Nevertheless such offers have, in the past, actually cut the airline’s profits. Stem:Which one of the following, if true, most helps to resolve the apparent discrepancy described above? Correct Answer Choice:CChoice A:Fewer than 10 percent of all air travelers make no attempt to seek out discount fares. Choice B:Fares for trips between a large city and a small city are higher than those for trips between two large cities even when the distances involved are the same. Choice C:Across-the-board discounts in fares tend to decrease revenues on flights that are normally filled, but they fail to attract passengers to unpopular flights. Choice D:Only a small number of people who have never before traveled by air are persuaded to do so on the basis of across-the-board discount fares. Choice E:It is difficult to devise an advertising campaign that makes the public aware of across-the-board discount fares while fully explaining the restrictions applied to those discount fares.
