The reality is all of those issues you mention are largely alleviated for frequent fliers, and I don't think that's a surprise given the revenues they generate.

The reality is all of those issues you mention are largely alleviated for frequent fliers, and I don't think that's a surprise given the revenues they generate. When I fly I get a free upgrade to economy plus (it ain't much but the extra legroom is nice) and occasional upgrades to first class, a free check bag, priority boarding, and priority security. And that's only with basic status. Checking in online and packing only carry-on means I can breeze through pretty quickly. Add a trusted traveler program and it's almost like flying 20 years ago. My guess is the goal of airlines is to encourage frequent flier loyalty by making conveniences a part of the status benefits, and then squeeze the occasional travellers for more dollars at the same time.
