I'm looking at an SDC situation which for me would be a first.
I'd like to take an earlier DCA-YYZ flight then I am scheduled for and subsequently an earlier YYZ-YVR flight. To do the change now is expensive.
Do I just show up hours early to DCA and ask to get on the earlier flight? If that works, do I go see the concierge in YYZ and ask if they can get me home earlier? I'm on an eUpped B fare for both legs.
