I have booked MEL - CNS on QF5946. Since I have a QF flight number, can I just waltz in to MEL and check my luggage in as per normal at the QF counters or do I need to line up and check in at the JQ counters? 
I guess my concern is will my luggage get across from the QF check in to the JQ plane?
Many thanks
