The GSA policy also imposes certain restriction on personal use of frequent traveler benefits. It states that employees may not select a traveler service provider based on whether it provides such benefits. “You must use the travel service provider for which your agency is a mandatory user. This includes contract passenger transportation services and travel management systems. You may not choose a travel service provider to gain frequent traveler benefits for personal use,” the rules say. Also, a denied boarding benefit (for example, cash or a free ticket coupon) is not considered a promotional item and must be turned over to the government.
