I have an economy RTW Oneworld Explorer ticket, whihc I assume is fare class L.
After about 1000000 messages to Qantas (they really, really don't understand RTW) I finally got them to check flight availabilites for a possible change/reroute.

One two flights (BA98 and 92 YYZ-LHR) they said "available but not in the same class"
Expert flyer, however, shows L3 for BA92 and L2 for BA98 -- which suggests there are seats available?

Not sure how these fit... am I missing something? Just want to make sure I get things right before the ardious challenge of dealing with Qantas' (uninformed) customer service desk.
