In a recent article on a proposed travelers’ bill of rights, travel columnist Ed Perkins had this to say: Airlines should make a reasonable number of frequent-flyer seats available to popular destinations, in all classes, at the lower mileage scales. Yes, I know that we accept the airlines’ unilateral frequent-flyer terms when we enroll. But the legacy airlines set us up the way street drug dealers do with addicts: First they flood us with miles and get us hooked; then they squeeze us to pay double or triple miles for the “free” tickets with which they hooked us. Those airlines have created expectations that, in all fairness, they should be required to satisfy.
