Go to http://www.oag.com and you can engorge on a huge menu of paper and electronic airline schedules, prices, routings etc. All are for sale but it used to be possible to try some of them for a month for free. I subscribed for a couple of years for paper and disks, but decided the disks were not worth the cost.
