Just in case someone is stuck in Bali and they checked OzBargain for whatever reason:
If you booked directly with Tiger:
Tiger's official stance is they will contact you however most of us go to Bali with no reception on our Australia numbers. Please keep an eye on your email or head to the airport and Tiger service counter will rebook you.
If you booked with a travel agent:
Speaking from Flight Centre, we have express permission to rebook customers on the next available. I'm not sure what other travel agents are doing. PLEASE contact your travel agent as soon as possible as seats are selling fast on AirAsia/Jetstar.
Gist of what Tiger are doing:
They are offering to rebook you on the next available ECONOMY class ticket, whether that be today or tomorrow. If tomorrow, they will pay for one nights accommodation up to a set limit (so no sneaky one nighter at the W).
They aren't sure on their future flights either as it was a snap decision by the Balinese Indonesian Government so if you are on Tiger for the next few days/weeks, keep an eye out on the Tiger website / get in contact with your travel agent.
Good luck!
