Malaysia provided a good example back then.
Jambojet has now surpassed what MASwings was and needs to be freed so it can transition to something like Firefly, or better yet Scoot.
Add Engineering, training & working with the Airports like Malaysia Airports.
If KQ must remain a flag carrier, viability will come from vertical integration, not scale. Grant it long-term rights to operate JKIA, align slots, terminals & pricing to its network, deepen regional feed via Jambojet, & optimize yield over volume. Hub Control is a must.
