American has greatly improved their online award search tool over the past year or so. Going back a bit over a year they only displayed American and British Airways award space on their website, while they now additionally display award space on Air Berlin, Alaska, Finnair, Hawaiian, and Qantas.
I’m sure most of us would love to see Cathay Pacific and Japan Airlines award space on aa.com, though instead we get award space on one of their few remaining OneWorld partners — Royal Jordanian.
Anyway, when searching award space on aa.com you should now see Royal Jordanian options show up. In North America they fly to Chicago, Detroit, Montreal, and New York. They also have some fifth freedom routes within Asia, like my flight on them from Bangkok to Hong Kong.
