allowable connections
 

Would someone please help me out. I can't for the life of me remember the answer to this one even though I've done it numerous times. Where do I go to find allowable routings/connections for a through fare from A to B?
Thanks

here's what i've done:
-go to expedia (http://www.expedia.com)
-click on the "flights" tab
-then click on the "Airline Fare List"
-then enter the appropriate cities/airports
-once you get the fares, click on "more rules..."

routing the near the bottom of the rules.
occasionally the routing is not there. i know not why.
