I just wanted to check something in my planning for a mhd. I'm not absolutely sure I understand the routing codes given in Expedia. Is it the case that where it says From-To, then any or all of the airports listed are legitimate connections? If that is the case, then is it possible to cascade routings? So, if one can go YVR-LAX via ORD, then is it possible to go ORD-LAX via DFW or OMA or whatever. Eventually you run out of time, obviously, but I'd like to know the options.
