I always get tickled when I see people make brilliant suggestions like this.
Do your research...Southwest has already raised fares several times.
You can only raise fares so many times until the customers say, "It ain't worth it." Then they'll either fly on your competition...or they won't fly at all. Southwest is a low-cost, no-frills carrier. Period. Just a few days ago, Gary said we were already seeing some resistance to our last fare increase.
And you suggest raising our fares again?
Of course, if you had half a clue of what you're talking about, you wouldn't even suggest such a thing, but then again, I suspect your motives are more about helping yourself rather than Southwest. Stop trying to play "Airline CEO" and educate yourself as to some basic airline economics. Then accept that when it comes to running an airline, Gary Kelly has you beat.
