The author is suggesting yield management to mitigate price arbitrage. Airlines have been doing this for years (maximize butts in seats & profit)., and require entire teams of business analysts to monitor the supply & demand of tickets, and reclassify seats so they stay balanced.

Every flight/hotel-comparison website has its goal to make the yield management team as ineffective as possible. Being too effective means running your suppliers out-of-business!
