Aviation Most flyers like their air rewards program, but some say points are worthless By Robert Silk / March 18, 2016 Share 1 -- More than 60% of people who are earning frequent flyer miles or points say they are satisfied with their awards programs, according to a study released by the frequent flyer credit card comparison website MileCards.com.The online survey of more than 600 adults was conducted by Google Consumer Insights on behalf MileCards in February.In response to the question, “Are you satisfied with your miles or points,” 53% of respondents said yes and another 9% said they are obsessed with the programs. Twenty-eight percent of respondents said they aren’t satisfied even though miles or points have value to them. One out of 10 respondents said the mileage programs are worthless.Despite respondents’ general satisfaction, 39% said that one thing that bothers them most about their miles or points is that flight awards are too costly. The answer came as several U.S. carriers have shifted from awarding flight miles based on distance traveled to awarding them based on ticket cost. It also comes as American Airlines prepares to increase many AAdvantage award prices next week, MileCards said. Another 31% lamented that award miles and points expire and 26% said the miles are getting harder to earn. Survey participants were allowed to list more than one item that bothers them.Among the survey’s other findings are that people earn more miles through the use of airline-affiliated credit cards than they do by buying plane tickets. However, airline miles are more valued than bank points and hotel points.In addition, a comparison of SEC filings conducted by MileCards showed that Southwest flyers are most likely among U.S carriers to be using miles. Twelve percent of revenue passenger miles flown on Southwest in 2015 were purchased with award miles compared with 7.5% by flyers of United, the second-place airline.
