I am assuming T+ fares so it would be 10. Its 10 from YYZ to PHX and when you throw in YEG to YYZ the system crosess out the extra 10 and states 10.

I just came back yesterday from YVR-LAX-YYZ-YOW and that was ten! Yes its long but better in J. As long as its AC and the same PNR, so muliti city booking and you give up any discounts codes, but save on duplicate security BS fees. Not many people do what i do, yes a few but not many, works out nicely if you like AC food
