This question is part CX but may be more applicable to the HK destination forum. Mods, if this is not the correct place to post, please help move.

Situation:

I fly into HKG on Sep 2 for the weekend and our to MNL for a day work trip on Sep 5. I will fly out of MNL to SIN via HKG on Sep 6. As I will have a considerable heavy suitcase from my stay in HKG, I am thinking of bringing a carry on to MNL only.

Question:

Am I able to check in my large case to SIN for the Sep 6 flight when I check in for MNL on Sep 5 and can CX store it for me?

There is a left baggage counter near T2. Am I able to deposit my bag there more than a day?

Worst case, are there are left baggage facilities in NAIA T3 (operated by CX or third party) if I have to cart all my luggage into MNL

Thanks in advance
