Hey travellers, TigerAir are having a domestic sale blitz with fares starting as low as $40. If you're looking to travel between May and September this year, then this sale may help you get you on your way for cheap.

Tigerair are offering two-for-one domestic flights across Australia, which means you can purchase one fare and get the second fare for free. If getting in a giant metal box with wings and travelling across Australia is on your agenda any time soon, then this Tigerair deal is worth considering.

Tiger Airways was once known as the worst budget airline in Australia. In recent times, the company has made some drastic changes to improve its reputation and claw back former customers. We were recently invited to test the airline on a return flight from Sydney to Melbourne. So has the Tiger changed its stripes? I put my body on the line to find out.

Tiger Airways and Jetstar are the cheapest airlines for domestic travel in Australia. Tiger is usually the cheaper option but, you really get what you pay for: bad service, uncomfortable seats, and a miserly baggage allowance. Jetstar is the better option although it's usually pricier. But there is a way around that.

Getting a good deal on an airfare is never unwelcome -- as long as you're on top of all the conditions. If you don't mind its stingy carry-on limits, Tigerair has just launched a new campaign, offering cheap domestic tickets every Saturday afternoon.

Travelling only with hand luggage saves you valuable time, but domestic airlines in Australia are getting much stricter about enforcing their baggage limits. Here's the current state of play for Qantas, Virgin, Jetstar and Tigerair, and the best tactics to use to avoid unwanted hassles or excess luggage fees.

If you’re flying Tigerair later in the week, it would be wise to check both your booking date and the weight of your carry-on luggage.

Tigerair Australia already has a deserved reputation for meanness with baggage: it charges a fortune for excess baggage and weighs your hand luggage before you board to make sure you comply with its limits. That process will now be even harder, since the allowed weight for carry-on has dropped from 10kg to 7kg.

Like any low-cost carrier, Tigerair makes a lot of its money from extra fees for selecting seats or being the first to board the plane. Its new Express Fare option for domestic theoretically offers a slight discount if you choose more than one of those at once -- but in reality it's just a way to get you to pay even more fees.
