Buying miles is a high-stakes strategy that can either save you thousands or leave you with a devalued digital currency. Expert consensus from sites like The Points Guy and One Mile at a Time suggests that you should almost never buy miles "speculatively"—meaning without a specific flight already in your sights. Review: Is Buying Miles Worth It?
: Airlines can change reward charts overnight, making your purchased miles worth less than what you paid.
: Just because you have the miles doesn't mean the seat is available. Always verify "Saver" award space exists before hitting the buy button.
