> There is no subsidize at all, an empty seat on a flight is an empty seat unsold, any money they can make back is extra profit. This completely disregards the opportunity cost of being able to sell the same seat. Even if the airline is absolutely unable to sell the empty seats cheaper, consider what consistently giving away seats for free would do to the remaining paid seats... > Airlines do not make money by flying…
What you said is true, but it pertains to how to balance the game once it started, while I was giving a explanation why the game is started in the first place. > consider what consistently giving away seats for free would do to the remaining paid seats After all those years it is still fairly niche because few people knew about how it actually works, and it took quite a bit of learning, with dedicated forum [0] exist…
I do however very much doubt that it’s somehow core to the economics of airlines. I think that the real power of rewards programs is that they exploit the principal-agent problem of business travel, with an added bonus of many people being very bad at redemptions and realizing how much they’re often overpaying for a few extra miles or status.
