I'm not familiar with QF's W plans .. is that NRT/FRA 3-class using a different aircraft type? What's happening there? Are they changing from fjy to jwy, or something else? MM works the cabins by assuming an aircraft type (e.g. 773 or 744) has a fixed configuration per airline (i.e. 744 is always fjwy), so if the aircraft type 744 maps to different configs (e.g. fjwy, jwy) then it means either a lot of manual tweaking, or we just live with it!
The QF 2 class 744s (jy) are currently being refitted into 3 class (jwy). They don't have any 744 fjy. These will be used mainly on SYD-NRT and SYD-SIN-FRA (though there are a few temporary changes coming due to the situation in Japan which will see the NRT 744 used on BNE-SIN for a short time).
The 4 class 744s will be getting reconfigged into 3 class (jwy - dropping f) as more 388s come online.
At the moment, QF has 5 different configs of 744. 3x 4 class, 1x 3 class and 1x 2 class.
By the end of next year, the current plans are to only have 3 class 744s - jwy and QF will only have F on 388 routes.
