Do not book with Webjet. They are a fraudulent operation. I canncelled my wifes ticket 3 weeks prior to the flight and requested the taxes portion of the ticket. Webjet refused. Airlines will refund the tax portion if a flight is not taken as the tax is not paid to goverments until the flight is taken. As a result of Webjet refusing to refund the taxes they can pocket the money as additional profit.
Estimate your luggage well: As cheap airlines are trying to minimize their costs they usually have a restrictive luggage policy. - You can board the plane with only one piece of hand luggage (usually not heavier than 10kg and with maximum dimensions of 55x40x20cm). For detailed information on hand luggage allowance check the website of the carrier. - If you plan to also take hold baggage with you, you will need to pay for it online (when you book your ticket) or at the airport. Keep in mind that it is cheaper to pay for your checked-in luggage online than at the airport.
