Why Airline Credit Cards Have an Enduring Appeal
New York Times
Mr. Sorensen, who runs the IdeaWorksCompany airline revenue consultancy, ran hundreds of simulations to come up with the following data for an award seat availability study he does with the rental site CarTrawler: The average value per mile redeemed for economy class travel ranges from 0.7 cents to 1.4 cents, depending on the airline. For long-distance business class seats, it ranges from 1.5 cents to 2.4 cents. So a 2 percent cash-back card would more often be a better value.
