I have too many nightmarish stories to write them all here...but I must admit they all sound quite similar to others already posted. I fly to the Gold Coast once every three weeks and I too am saying I will never fly again BUT unlike some of you have mentioned here - I will not be going back again. Sale or no sale (in fact i have vouchers I have torn up because I simply am not interested in flying with them ever again) You get no service, arrogance and confusion! I do realise they are an economy airline, but so are Virgin and Tiger. I have had NO issues with Virgin....and I've had MANY with Tiger LOL But the difference is you have to expect them with Tiger - you fly at your own risk. Plus there are no hidden secrets with Tiger - they are a discount airline and you are told several times the fee structure and how to check in etc without building more fees. Jetstar have rules and regulations that change daily. I firmly believe the harder you search for rules and regs or baggage limits and prices on their website the dumber you get.
P.S this site is bloody awesome. :)
