Spring of 2009, making the round trip chart to one-way chart, did away international stopover but at North America gateway stopover when an international award involved North America which is defined in its geographic sense. Mileage required did not change.

There is no telling when and if AA would change its award chart again.

You do realize that a ticket has only 12 months validity started from the date the ticket is issued. So your statement of "travel later" needs to have a time line.
