I recently wrote about the free one way options using American Airlines, and in that I referenced just 6 major hubs where this works on. Brian, a reader of the site pointed out that it could be done on more than just those, so I started digging a little to see what other options were available and struck gold.
It turns out, that when you start including travel booked on the One World Partners of American Airlines the options are a lot wider that I first thought, here is a list of airports and valid gateway cities for them based upon the partner that you are flying on.
Let me know if you have any questions on how to use this, and if you have any other airports or airlines that I missed, and I will update accordingly. Read more on how to get these free one ways here:
