Every Flight. Baby Free. I'm sort of surprised an airline hasn't tried this yet. Being stuck within 15 rows of a screaming infant on a flight is just about the most torturous experience we face in our lives. And when it's the preamble or the conclusion of a vacation, it's unbelievably annoying. I'm sure an airline would be scared of alienating new families, who then could become used to using another carrier, once past the infant stage. But, if I could know that there would be 0% chance of me hitting the baby lottery on my next flight...I feel like an airline could gain a lot more than they'd be losing. And I think those very families who would have to fly Southwest for a couple years would come back, too.
