So they STILL havent sorted this out then? I emailed them about this when I was looking at LHR-BUD-ARN for £330 and got this reply:

"Dear Mr. Koksy,

Thank you for your message to American Airlines about business class on Malev.

You are correct. While Z class is business class on American Airlines, the designation of "Z" on Malev iis for economy.

If you select Business Without Restrictions you will receive a Business class fare, however, it is not the lowest fare they offer. In order to book the lowest Business class fare you will need to contact American Airlines Reservations or Malev Reservations by phone. Ask the phone agent about booking a fare with an "I" class. This fare will be £962.30.

We have reported this issue to the appropriate department and to the programmers.

Our AA.com Web Services will best handle your questions and concerns regarding this issue. Please call for immediate assistance.

We appreciate your patience while we continue to technically fine-tune American Airlines website, AA.com."
