They seem to have spat the dummy on all the three routes they transferred to Tiger i.e. MEL, PER and ADL. In addition to no MEL-DPS you now have other anomalies such as flying PHE-DPS but not PER-DPS, the latter having Indonesia AirAsia (3 per day), Jetstar (3 per day) and Garuda as well. The booking engine shows the cheapest option for PER-DPS as a 15 hour trip with connection in BNE !
