Qantas would smash them. So would Virgin Mk 2 if it gets up. Look at Rex's track record. They move in on someone else's turf like in WA but when Q/link move into there turf such as in SA they chuck a wobbly. Pull out of KI and threaten the same for Whyalla claiming unfair competition. Constantly whining about airport fees etc ,always looking for taxpayer/ratepayer assistance and screw their workforce to boot.
If they went and played with the big boys on trunk routes it would be Compass all over again....I give them 6 months.
However what they may like to consider is smaller jets on their long routes such as Sydney- Broken Hill etc, that might work.
