eachself - A word for when you're so proud of yourself you think you're

A word for when you're so proud of yourself you think you're flying twice on the same flight and still get a discount.

I did eachself on the same flight. I'm so proud of myself. I don’t even care that I’m sitting next to me.

Eachself is when you think you're being smart, but you're just being a fool with a discount.

I did eachself on the flight because I thought I was saving money. Turns out I was just being a fool.
