You're the second person I've seen post this about airlines in the past two days (I believe the first was on Reddit). I have thought about it and don't actually believe it's 100% true. People buy what's cheap at the time they need the ticket. The problem is price variability/gaming by the airlines. You can very easily see >100% variability in the price of the same ticket from one day to the next, and it has nothing to do with objective variables. It's pure price manipulation, just like everything else airlines do (baggage, food, boarding order, upgrades, elite lounges, free drinks, point bonuses).
