A bit of helpful news for AAdvantage miles holders: you can now search for award availability on British Airways, Hawaiian Airlines and Alaska Airlines on AA.com. Apparently Alaska has been available for some time, but BA and Hawaiian are new. Unfortunately, BA awards are pricing fuel surcharges correctly, which is a giant bummer (unless you enjoy spending $1,000 in addition to using your miles).
You can search itineraries originating both from the US and overseas, which is helpful if you’re looking at intra-Europe flights on BA.
There don’t appear to be any bargains in the new functionality, but AA’s tool is easier to use than BA’s (and I find it easier to use, though far less comprehensive, than Qantas, which has been the go-to search site for Oneworld award travel).
