I know there is a related thread open now (concerning MLL), but I didn't want to get shot doen for "hijacking" that thread...
I have Aeroplan tickets YYZ-DEN-SAN, with the DEN-SAN portions (confirmed O-class) on UA. While I know I will have MLL access in YYZ on departure (D-class), will I have RCC access in either DEN or SAN? I've checked both forums (albeit briefly) and found somewhat contradictory answers.
