Impose penalties on airlines for delayed or canceled flights.
Why is this important?
I missed my brother's graduation because of a 17-hour flight delay, due to maintenance. They wouldn't even put people up in hotels. I know so many people who have spent nights in airports and on planes due to overbooking or late flights. People missing weddings, funerals, important meetings. The money that is lost due to thousands of people sitting around in airports waiting for their delayed flights has got to be astronomical, and it has a negative effect on the economy. The airlines keep doing it because they can. They have a monopoly. Without a government-imposed penalty system, this will never stop.
