She can call for a hearing on the matter all day long but Congress needs to stay out of it. This is another gotcha moment coming from the Democrat party and Republicans better not fall for it.

Smart Republicans should get out in front of the issue. It is really simple to end the problem of passengers getting bumped so that airlines can save money relocating their crews. Right now DOT regulations control many aspects of involuntary bumping. All that is needed is to increase the involuntary bumping fees to a large amount. If United knew it would have to pay, say $10,000 per passenger it bumped in order for one of their employees to take their place they would find another way to move their employees.
Doing so would have minimal effects on the costs of tickets since airlines rarely fly with any empty seats, and rarely do airlines have to bump passengers to move crew members.
