I totally agree with your complaint. i am now the passengers that will fly to australia about this coming August. I had been changed the flight one time from Brisbane to Sydney (TT6108) by tigerairways call center from morning time to evening time. In that time we had accepted and we must change the plan for the new flight. But!! Now, i am checking the status of my new flight.
It is showing us the status of our booking are cancelled!!! this is the twice shocked for us!!
What does it mean? i do not understand the system of your operation, Tiger Airways.

Consequently, I must request to have tourism visa to Australia very soonest. I must use the schedule to submit for the australia embassy.But your company made my schedule changed. and Moreovers, we expected to have a refund for our payment soon!! No more Tiger Airways!!
