New York's Senior Senator

I'm all for Chuck Schumer's recent efforts to restrict carry-on fees that airlines might charge their passengers.

One point of advice for the senior senator, though: what you have facilitated is known as "collusion." Any agreements the airlines have made to you will be void if challenged in court, assuming whichever court might hear a claim follows the law.

Is there some sort of legislative immunity senators have to allow them to broker illegal deals?
