Are frequent-flier awards worth all the trouble travelers sometimes go through to rack up enough miles for a free trip ? Not according to a lengthy piece in th e May issue of Worth magazine , which concludes that the programs are vastly ove r-rated . Then why do so many banks , rental-car companies , long-distance phone services and hotels reward their frequent customers with airline miles rather t han cash discounts or other perks ? Simple , says Worth contributing editor Jeff Blyskal , in the article entitled `` The Frequent-Flier Fallacy . '' Companies want to give premiums that combine the greatest perceived value with the lowest possible outlay , and frequent-flier miles are the perfect solution . Each freeb ie ticket costs an airline only $ 11 to $ 42 , Blyskal calculates . The average discount to passengers amounts to 3.3 percent almost 2 percent less than you get by being a valued customer of Sears , he writes . His data showed the cost to a traveler for each award ranges from $ 929 with Southwest Airlines to $ 7,527 wi th Delta , which requires higher-than-average mileage minimums to collect a free bie . The dollar value of the freebies ranges from $ 56 with Southwest to $ 208 with United . The effective discounts passengers reap range from 1.5 percent ( U SAir ) to 6 percent ( Southwest ) . Hotel frequent-guest programs typically prov ide a 5 percent discount , as do numerous retailers ' programs , including Sears Best Customer , Blyskal found . The number of dollars spent to earn a domestic freebie usually available after flying 20,000 miles typically ranges from $ 3,62 6 to $ 6,555 , he said . ( On Southwest Airlines , the average passenger gets a free trip after 7,104 miles because freebies are awarded by that carrier after e ight round trips rather than a mileage minimum . ) Blyskal says his accounting s ystem gives airlines the benefit of the doubt in every aspect and was based on t he programs as they stand now before the program devaluations most airlines plan starting next year . The payback is even worse from affinity credit cards , he says , which generally award one frequent-flier mile per dollar charged . This t ranslates to an effective discount of just 0.7 percent on $ 20,000 in credit car d spending needed to earn the $ 152 in value of the average free ticket , Blyska l figures . All in all , he says , to earn these paltry awards , travelers spend more on air travel in the first place than they have to because they often shun low-cost airlines that do not participate in frequent-flier programs . For exam ple , he says , to earn 20,000 miles on United , a traveler would have to make 1 4 Newark-Chicago round trips at a cost of $ 12,348 . Fourteen round trips would cost just a quarter of that $ 2,912 on upstart Kiwi International Airlines , whi ch offers consistently low rates but no frequent-flier perks , he says . You say you don't care about the price because your boss pays for a lot of your flights and lets you rake in the resulting frequent-flier perks ? Don't let the company bean-counters get wind of the fact that you could be sent on 45 more Newark-Chi cago business trips for what it 's costing to ensure that you get your perk , Bl yskal cautions . Add on the annual fees charged for some affinity cards , not to mention high interest on purchases and maybe a computer program to help you man age your miles . And , of course , most travelers who earn a freebie purchase a ticket for their spouse or companion to accompany them which often isn't availab le at any discount whatsoever . Plus the hardest cost to quantify which may be t he biggest cost of all , Blyskal says : the time many fliers spend obsessing ove r maximizing mileage for minimum payback .
