Under the new regulations, airlines operating domestic flights will be able only to keep passengers on board for three hours before they must be allowed to disembark a delayed flight...

From January to June this year, 613 planes were delayed on tarmacs for more than three hours, their passengers kept on board.

Airlines have strongly opposed a hard time limit on tarmac strandings... past efforts to address the problem have fizzled in the face of industry opposition and promises to reform.

Clearly, Libertarian theories about the marketplace are correct, and Government regulations are never necessary. Thats why the airlines reacted to widespread outrage over tarmac strandings by creating their own reasonable policies and communicating them to them public. Oh wait, actually that is not at all what happened.
