Regulate airlines by setting minimum standards that provide sufficient space for passengers and their carry-on luggage.

The fleet, equipment and seat layout of domestic US airlines target maximizing profit with no regard or respect to the traveling experiencing of the American people.
Airlines and their regional associates cram passengers in inadequate sized airplanes with configurations that include uncomfortable seats, small airplanes, insufficient space for passengers and their carry-on luggage. Guidelines to dignify the travel experience in the United States should be established.
In order to operate in the US, an airline shall provide adequate room for the average height, size and weight for the average American and enough room for each passenger to bring a carry-on suitcase on-board.
In addition, evaluate if the HUB and spoke model leads to monopoly practices in detriment to the American travelers.
