I think overall you overestimate the amount most people fly. Generally, many people fly very little or almost never. Sure, there's world travelers that know who are bad airlines, but knowing the 'secrets' to not having a bad flight is assuming a lot of the average occasional flight consumer.

And the people who fly a lot? Almost all of them are flying on business, on somebody else's money.

Which is also why the hotel where people stay when they're visiting friends has free wifi, and the hotel next to the convention center does not.
