ms101 as I said in post 599 of this thread " If the next destinations are Tokyo and Sao Paulo rather depends upon the number of Qsuites aircraft available.". QR cannot use aircraft they do not have!
QR probably have a wish list for Qsuite destinations but even they are unsure of when Qsuites can be introduced for a destination. Given the problems caused by aircraft availability QR are wisely not saying anything1
