Eg YYZ SEA will show as YYZ YVR SEA max on ac.com but you could go through every single province if you wanted to pull a Cow

*Note: The only time I have done this was a non complex routing between YYZ and Quebec City...so I'm no expert, but that was the advice given to me when I asked about a YYZ SEA route (which permitted me to go through DEN of all places!)
