I'm going to do a JFK - HKG sector (transit in SIN) by SQ in suites/first class.

Wondering if there's any way I can get my checked baggages out in SIN during the transit and store it there for a couple of days?

A detailed plan :

JFK - SIN
Long transit in SIN without clearing immigration
Collect checked baggages and store it in SIN Changi Airport
SIN - HKG
(worktrip)
HKG - SIN
Collect checked baggages
Clear immigration

The reason i'm planning to do this is because I will have a lot of baggages from JFK-SIN which I don't want to lug to HKG.

Thanks!
