I will be travelling PER to HKG, but to capitalise on SC, I will be flying PER-MEL-SIN-HKG all on a VA flight number, but the MEL-SIN-HKG will be on SQ metal. Flying in Y. When I check in at PER, I presume my bags get checked through to HKG, but do I get all my boarding passes at that time? Someone told me I need to obtain the SQ leg boarding pass by checking in at MEL. If so, as SG, can I check in at the Business counter? On the return leg, I will be going HKG-SIN-BNE-PER. Again, I presume my bags are tagged through to PER, but do I need to collect the boarding pass for the VA leg in BNE? Also as SG, will the bags be tagged Priority? Thanks in advance.
