Just thought I'd let everyone know that I now have a paid ExpertFlyer subscription of my own (with unlimited queries), so I'm more than happy to check the availability of exit row seating (or any other specific seats) to anyone that asks (as well as flight loads (via fare buckets), domestic upgrade & award availability etc etc etc)!
Through using EF, I was recently able to book flights around exit row availability (which Qantas doesn't let you see online before you pay)... I'm glad I did it this way, as one of the flights that I was originally going to book had NO EXIT ROWS available (despite being in January next year), but I was able to book a different flight that departed within an hour of the original (both A380)... in doing so I scored row 79 seats on 4 A380 flights (MEL-SIN/SIN-LHR/MEL-LAX/LAX-MEL), exits on B747 (FRA-SIN) that are not impacted by a protuding escape slide (and aren't close to the toilets), and row 45 exits on A332 (LAX-JFK).
