I fly Southwest specifically because they don't charge to check bags (seriously, fuck this nonsense of charging for basic functionality). I find that it's actually very rare that the overhead bin space fills up, even on completely full flights. I think that the GP is spot on that contention for the bins wouldn't be nearly as bad if checking bags was free (which again, it bloody well should be even if it didn't help the bin situation).
