What is going on, most likely, is the final details of the Malév (and JAL) relationship haven't been worked out and / or AA IT hasn't received the details in time to post all the information we need.

AA is also slow on the uptake. Witness, it is April 1, and on aa.com, Aer Lingus is still listed as oneworld, which is no longer true, no fooling. Japan Airlines and all its symbiotes, also now oneworld, are not listed as such, though, mirabile dictu, Royal Jordanian and its details has been listed for a few days.

The oneworld website has been updated, I see - but it isn't of any particular help in terms of which fares earn what. From that site:

"oneworld today completed the biggest expansion in its history with Japan Airlines, Malév Hungarian Airlines and Royal Jordanian all now offering the alliance's services and benefits as full members, along with LAN Argentina and LAN Ecuador and five JAL associates as affiliate members."
