You're basically saving some money on the ATPLs which equates to 10 h on the hour building
The integrated versus modular route has been discussed elsewhere on these forums but I don't have heaps of money and at the end I shall do the flight instructor route at CATS then deal with the airline bit with hours under my belt in a couple of years
If its integrated you want then CATS provide the material to WAAC so you can have both but you have to up sticks to Australia for a year
As for airline job at end, I see CATS students filtering in every couple of weeks to tell their airline tales which is a considerably positive point about the set-up
