This is a clickbait title that is totally unsupported by the article itself.
The article just confirms what people do:
> The same can happen with plane tickets: when people visit a website like Google flights or Kayak and search for a ticket, a wide range of different flights from the same airline appear. Travelers tend to make selections that balance convenience and price. The price of one flight might push people to select a slightly less convenient but cheaper flight.
The article then describes certain aspects of how airlines set prices, but it never substantiates the headline claim about comparing fares being a waste of time.
