Yes, it's the JAL's flat bed.
I think TG
wants to use those 772 for Japan routes. BKK
etc. Because those are one of the most profitable routes for TG
. So I think TG
wants to make it nice.
I remember that TG
put the 772 for Melbourne route (You can check the pic og TG
772 at MEL
). So they may use 772s to Australia too.
Let's just blame it on yields.
