The dynamic fare pricing system is based on demand and supply, as the demand increases price also increases. That means the cost of fare increases as the number of tickets sold increases. The Flexi fare system is applicable for premium special trains like Rajdhani Express, Duronto Express, Jan Shatabdi Express, and Shatabdi Express. The First 10% of tickets are sold at base fare but later on, it will increase by 10% with every 10% of tickets sold. This goes till 50% and after that rest of the tickets are sold at 1.5 times the base fare. For 2S, SL, CC and 2A class, fare increases between 1X to 1.5X whereas for 3A class remain between 1X to 1.4X. This pricing system doesn't applicable for 1AC and EC classes as it is sold on base fare only.
