The problem is lack of information at time of purchase, in both cases. It's so onerous to figure out what these products are doing that people give up. Same in the airline case. If any of the airlines actually provided better service at a higher price, they'd have a market, but it's impossible to assess that as an end user with all the fake review bullshit that's all over the Internet these days.

The only cases where it's clearcut are a few overseas airlines like Singapore Airline who have such a rock solid reputation for great service that people will book them even if the price is 2x.
