ATC uses the prefix XAX (Xanadu)
BTW I hope the Flt Ops guys in Air Asia X take note:
3 of your Xanadu flights arrive almost same time
at KLIA with the c/s ending with 7.
XAX547/XAX507/XAX527 (not too sure of
the flight numbers but very sure it ends
with the number 7. This can lead to c/s confusion.
Not good for ATC and pilots.
