I booked a roundtrip Business Class award flight for myself, wife and parents HKG >BKK >HKG. I then purchased roundtrip ticketsBusiness Class from MNL > HKG > MNL, my final destination, so its 2 separate bookings. I am wondering of its possible to ask the agent at check in to check us for both flights there in BKK, BKK>HKG, and then HKG > MNL and check my luggage all the way through, saving me the hassle of going through immigration, collecting my luggage and then checking in again for my HKG > MNL flight, and going back through immigration again?

Any advice would be greatly appreciated. Thank you in advance.
