I was just reading Plane Talking, a great Crikey blog about everything flying related in Australia. Apparently, Tiger is going to start flying from Adelaide in November and is going to kick off fares for $20. I can't find this mentioned anywhere on the Tiger site otherwise it would be a decent deal (Jetstar is $60 one way). There appears to be a Stripes deal in 24 hours time, so that may be where it will be announced?
