I have a question about this. I am frequently reading that routings are not allowed due to backtracking. Is this correct? Do routings have to be within MPM AND have no backtracking? I want YYZ-ORD-DUS-CDG-BKK and BKK-HKG-ZRH-FRA-MUC-JFK//LGA-YYZ. Both ways are definately backtracking but they are well under the MPM.

I called Aeroplan and asked about backtracking (didn't give my specific itinerary) and the agent said as long as it's within the MPM and I don't go back and forth between regions it should be fine. Is that correct? He seemed unsure.

Thanks!
