My website (airlinecrewhub.com) had a page with flight schedules. It was getting really popular but FlightStats wanted to start charging me over $500 per month just to access the data. I was barely in the black at about $70 per month! These data companies guard their schedule info and charge a big chunk of money to those who want the info. Ad revenue is not enough to pay for the cost and flight crew are too cheap to sign up for subscriptions. If somebody has any ideas, I'm all ears. The site still exists... It's just on pause.

I also had a really good idea for loads but that got shelved when I shut the schedules down.
