Pick your destination and reserve a seat on your chosen dates at the Tiger Airways website. The flight to your destination will probably depart in Singapore if you are outside Australia. Be sure to schedule a flight later in the day so you will have enough time to get to Singapore, or your connecting destination.
Find a flight from your origin to your connecting destination. Look at the same dates for flying, but schedule your connection at an earlier time and your return connection at a later time than your first flight. Tiger recommends a three hour layover between connections.
Pay for both of your "Flight Combo" flights at the same time on the Tiger Airways website.
Check your visa status for not only your destination city, but also your connecting city. You will have to clear customs and immigration in the connecting city to check in for your second flight and complete your itinerary. Check visa information for your connecting city, which will likely be Singapore, in the Resources.
Follow the crowd to the immigration control area at your connecting airport and have your passport out at the appropriate checkpoint.
Collect your luggage, if you checked any, at the baggage area.
Clear customs with your checked luggage.
Walk to the "Departures" hall and find the check-in counter for Tiger Airways.
Show your passport to check in for your next flight.
Check your bag, if necessary, and take your carry-on bag through the security checkpoint to re-enter the gate area.
Walk to your departure gate and get on your onward flight.
