This site is $20 for a year subscription but will give you a good idea of the loads on all airlines except southwest. Use coupon code 20723 for $1.50 off.
ASU.COM has a solution called TripCheck. It is actually better than Flyzed as it gives actual numbers, alerts, Zed prices and airline phone numbers. I have used it for a year or so and it works fine. You can find more info at: Sign Up For Tripcheck - ASU Travel - Interline discounts for over 40 years
I saw a website once that you could put in any 2 airports and it showed you every possible way to get there in a really simple chart, anyone know what it is?
