Based on reviews, the airlines providing the best frequent flyer programs are JetBlue, Southwest Airlines and Alaska Airlines, according to U.S. News & World Report. United and American Airlines are also among the top five.
Reviewers consider JetBlue TrueBlue to be the best frequent flyer program for three main reasons: They allow members to book on other airlines, there are no blackout dates on JetBlue flights, and members can earn additional miles through social media or by using the JetBlue credit card. Southwest Rapid Rewards is also highly rated for their lack of blackout dates and for the ability to earn hotel rewards and miles that can be used on Southwest or AirTran. Alaska Airlines stands out because they offer miles on other airlines, have earning opportunities through other companies and have flexible redemption options.
