I have a one way flight (LAX-YYZ-FRA-BUD) that I purchased as a mixed cabin (econ from LAX to YYZ, business from YYX to FRA, econ from FRA to BUD) on Air Canada. I know I'll have access to the Maple Leaf Lounge in YYZ, but I am wondering if I would have access to any lounge in FRA considering the last leg of my trip is in economy. Thanks!
