No they can’t. If they can provide enough non-stop routes to unique city pairs combined with a product that directly steals legacy pax they might be able to claw their way back. That being said they’ll never be more than a small pest that the big 3 have to occasionally use their CC revenue to swat away. Or they’ll have to do the AS thing and just become a regional feed to one of the big 3. Either way this and other blockages of future mergers amongst B6/NK/F9/HA/G4/AS will only continue to result in higher prices. But overall I agree with you, the legacies have too much of a stranglehold on the industry and now given the superpower of CC revenue to run their entire domestic network at a loss if need be they are essentially unstoppable. Only path forward here to competition is consolidation amongst the smaller airlines.
