Hi,
I was wondering if anyone of you guys could help a 20 year old girl who is NOT a seasoned traveler and is new to booking tickets from different airlines just to save some extra bucks on how to handle things like collecting of bags/transfer of bags to my next flight and , do I have to go through immigration and customs and etc,.. i am just at lost to this

anyway, my exact situation is,

i am planning to book in advance 2 tickets from different airlines to reach my destination which is Cebu just to save some cash. My first flight is by Jetstar which leaves Perth on 05/12/12 at 00:15 and arrives at Singapore at 5:30 am. My second flight , which is bound for cebu is booked through Singapore Airlines, so I'm guessing silk air would be the one used for the flight and this deaprts SIN at 9:05 am.

so my question or rather problem is,

a) how would i go about the process of transferring my luggage from my previous flight to my next one? (dumb question, i know just really need to ask)
b) would it be better if i go through immigration, customs then collect my bags then check-in right away? any other reccomendations?
c) if i do go through the whole process of immigration and what not, what do i write in the disembarkation/embarkation card since i'm not leaving the airport? are there extra fees charged when you go through customs when you re check-in again?
d) would the time between 5:30-9:05 be enough to do all of this?


and one more thing, the ticket i'm gonna book through singapore airlines is going to be paid by paypal, and since the carrier during the flight is silk air would they still ask for credit card verification/ LOI or any other verification? well ofcourse besides the boarding pass and passport they do but are there still any other things they ask?


I hope someone could help me cause i really really need it!
cheers!
