What different ones? Do you live in the US? There are 30ish percent less airlines than there were in 2009 due to consolidations. There are hubs where airlines monopolize entire airports and drive costs up.
Have you ever been to Europe, if you are living in the US? I'd like you to compare costs of flying regionally there compared to here.
Airlines are just another example of oligarchic control - it's incredible that people are expressing sympathy here as if the consumer and the airlines are on equal footing. I hope you enjoy your customized dynamic pricing based on personal information they've collected about you.
Fuck you, airlines.
