United Puts Limit on Frequent-Flier Miles

United Airlines, the world's second-largest carrier, said it will cancel frequent-flier miles for customers who go 18 months without using the program.

Travelers can keep their accounts active and retain their miles by flying the airline, using a United-branded credit card, or using or donating miles, the Elk Grove Township, Illinois-based airline said Friday in a statement.

United's move cuts in half the previous three-year limit on dormant accounts, making the policy among the airline industry's most restrictive regarding existing frequent-flier miles.

Carriers use the reward programs to win repeat business. Frequent travelers will benefit "because there will end up being less competition for award seats" as other customers' miles expire, spokeswoman Robin Urbanski said. "We are focused on treating our best customers even better."
