The violent ejection of a United Airlines passenger from a flight bound from Chicago to Louisville appears to have marked a long-awaited turning point. David Dao, 69, suffered a broken nose, lost two teeth and faces reconstructive sinus surgery. At last, America's long-suffering flying public is crying as one, have you commercial airlines no shame?

How will the politics of protecting travelers from rapacious — and sometimes brutal — air carriers play out?

Or will U.S. President Donald Trump's Congress be forced to act?
