B6's recent announcement that they're planning on starting EWR service had me wondering...
Why do the legacy carriers never try to encroach upon each other's territory. Clearly, at least in hub cities, there are travelers with loyalty to a certain airline, but that hasn't stopped any of the LCCs from trying to move in.
For example, why hasn't CO tried to move into MIA? Or AA try to gain a foothold in DTW? Etc, etc.
It might seem like a stupid question, but I really became more curious the more I thought about it, especially considering that all of the LCCs have no qualms about diving into a legacy carrier's fortress hub.
Is there some sort of gentleman's agreement between the Big Six that keeps them from competing on the same routes and cities, or is there some other force at work here?
I would love to hear your opinions.
