the catch is that the vpn connects to the poorest areas of the country you live in
A common mistake.
You're going to get a worse deal if the airline thinks you're not going to be a repeat customer or part of a larger network of frequent fliers. The customers who get the best deals are the ones that airlines believe they will be able to collect money from routinely. If they have you pegged as someone who will only ever buy a ticket once or twice in their lives, they're going to try and sell you the worst possible seat at the highest possible price.
What you can expect as a poor buyer is debt-financing, bait-and-switch, and the worst kind of economy service at the highest marginal price point. Budget airline travel is miserable and AI isn't going to make the experience any better.
