Friend plans to go YYZ-LAS-DFW-YYZ, stopping at each city for a few days.
He consulted Travelocity and Expedia, but they consider the itinienary (sp) as multiple one-way trips, which means expensive for him.
So all wise men at a.net, any less expensive way to fly this trip?

Go to www.Flyertalk.com and ask your question. They live for that kind of stuff.

You should try your travel agent for this one. You could possibly do YYZ-dfw-LAS-DFW-YYZ, only adding DFW on his way to connect on another AA flight, but stopping at DFW will cost more.
