Thanks to all the concierges I never see -- working behind the scenes to get me where I want to go faster!^
Like today when I called to get earlier flights (outbound and return) on Tango Plus fares on oversold Jazz flights YYC-YEG-YYC. Got boarding passes on both flights (one on arrival at the desk and the other I had to wait for the plane to load before the GA issued the lone boarding pass). I have yet to be charged for any same day change since becoming SE again. That has involved at least 8 same day changes.
