Price Discrimination Strategies in Airline Ticket Pricing
Quick fact
Airlines can charge over 10 times more for a ticket purchased at the last minute than for one bought months in advance, and the exact same seat can be sold at wildly different prices to different passengers.
Why this is interesting
Ever wondered why the person beside you on a flight paid half the price for the same seat? Airlines have turned pricing into a science that charges each passenger as much as they're willing to pay.
