A specified period when a particular service, offer, or promotion is unavailable is often designated. This restriction can apply to various sectors, including travel, entertainment, and retail. For instance, an airline might restrict the use of frequent flyer miles for booking flights during peak holiday travel periods.
This practice is implemented for several reasons. It enables organizations to manage demand during periods of high activity, optimize revenue, and ensure service quality. Historically, such limitations were a standard practice for businesses attempting to balance supply and demand, particularly during predictable seasonal peaks. The limitations help businesses to avoid overextending resources and preserve service availability for paying customers.
