Why the Person Next to You Paid Half Your Fare

Episode 12  ·  Why one airline seat has many prices: booking classes, revenue management and the computer that decides  ·  all sources

Two people can sit side by side in economy, in identical seats, and one can easily have paid twice what the other did. This film explains why: airlines sell each cabin in booking classes, each with its own price and rules, and a revenue-management system decides how many seats to sell in each, flight by flight, until the door closes. It follows one seat, 14C, from the day it goes on sale to departure, and tells how the method was built by American Airlines in the 1980s in its fight with People Express.

Visuals

• All animation, planes, seats, airports and diagrams were created by ColdProvenance for this film. No footage or photographs appear in this film.
• Seat 14C and its passengers are illustrative. The balloons (a higher balloon means a dearer fare), the price tower and the pricing machine are visual metaphors for booking classes and the revenue-management system; their numbers are the sourced figures. Planes and liveries are generic, not real aircraft.
• The two neighbours paying "twice" is an illustration of what can happen, not a documented pair of tickets.
