Most airlines use this system of Dynamic prices in which an algorithm uses data from supply and demand, time, competitors prices, groups of customers and other factors to determine the current price for a ticket.
This has been a technique used from the very beginnings of human civilization since prices have always fluctuated according to external factors.
Dynamic pricing, is how flexible products can be priced differently for different people or in diffrent times.
This means online companies can easily adjust their prices such as ticket buses which may be adjusted according to the season , they may be highly priced during busy seasons such as holidays and be lowered during slow season. Hotel rooms also can fall under this pricing , during busy seasons prices will be increased and during off season customers get discounts. customers can be charged diffently for the same product such as kids paying less than adult.
