Online miles broker refers to an intermediary service that facilitates the exchange or transfer of airline loyalty miles between eligible parties, subject to the terms and conditions of applicable loyalty programs. In the USA, the term is commonly discussed in the context of travel rewards, mileage management, and frequent flyer account strategies. An online miles broker may assist with transactions involving reward balances, although the availability and legitimacy of such services depend on individual program policies. Online miles broker activities are often evaluated based on compliance with loyalty program rules, transaction security, account verification procedures, and applicable regulations governing travel reward programs.
