Credit Card Scheming and my experience with Jetstar Mastercard

This is my experience with saving with the Jetstar Mastercard. It is the first rewards card I have had.

1) Applied and made a purchase, which entitled me to a $100 flight voucher. It's advertised at $50 on the website, but they sent a $100 voucher, maybe because I'm on the Jetstar mailing list? = + $100 FV.
2) Going overseas so booked a flight, topped up my health insurance, and made general purchases for about fourteen days, spending $2500 in total, which gives me $25 flight credit = + $25 FV
3) Paid off everything on the card, rang them up to get a $2000 balance transfer from my other CC, with 0% interest for the first 6 months since card activation
4) Put the $2000 I am up by in a Ubank Saver for 5 months, enjoying 6.51% interest, giving me $54.25 interest = $54.25
5) After the five months (5 1/2 months since card activation) used the money in the bank to pay off the Jetstar Card

So, taking into consideration the $50 annual fee, in six months I have made $4.25 cash and $125 worth of flight vouchers. This could have been more if they gave me a bigger CC limit. Now I will continue spending on the credit card as normal to accrue further points for the remainder of the year, so I think I've done pretty well.

TIPS Learned:

• You don't have to take up the introductory transfer deal immediately, which allows you to make initial purchases to get the bonuses, pay it off, apply for the transfer, and not have to worry about paying interest in what you initally bought. This method probably applies to all cards in general.

• The credit card balance transfer was simply processed as a BPAY payment to my other credit card, so if the non-Jetstar credit card has a balance of $0, you could actually apply for the balance transfer, get $2000 (or whatever) transferred into that account, and use it as cash! If Jetstar give you a $10000 Credit Limit, then you could do a 0% $9500 balance transfer, stick it in a saver, and get around $300 interest from it. Just before the six months, pay it back!
