Problem is TA's not airline's, so this is not like the QF/AA or BA debacles.
Question is whether the big O will honor the fare and whether it's worth it to fight with them until they do! Someone would have to be pretty litigious and with a lot of time on their hands to do so.
I think AF has a similar problem with their A class for Premium Econ while other airlines use it as First.
Still, a nice looking ticket!!!
