Cost Per Mile Web Tool?
A lot of times, I'll search for airfares, regardless of destination. Since I'm willing to travel anywhere and explore any/all cultures, I'd like to know if there is a web tool out there that calculates the best airfare deals based on Cost Per Mile.
I basically just like going to far away places, as long as I know that the fare I got is a really good deal (ex. IAD-MIA-IAD may be $200 and a pretty good deal, but maybe IAD-NRT-IAD costs $620, and that's an even better deal. Sure, it's more money, but it's a cheaper cost-per-mile).
See where I am getting at? I don't care where I go, I just care if I can get somewhere far away, and it's a really good price to do so.
Any help is appreciated. I apologize if I posted in the wrong forum.
