So we all know you can use hidden city tickets to get to places like Istanbul for less than the required 37,500 Aeroplan miles. You just buy a 30,000 miles ticket to a European city, opt for Turkish Airlines with a layover in Istanbul, and then simply get out.

But are there limitations to how far you can push this logic?

For example, can I do the same thing by buying a 30,000 miles ticket to Europe that connects through Delhi, the Air India hub? That would get me to Delhi (normally 50,000 miles) for just 30,000.

Or what about buying a ticket to Europe with EVA Air, or Air China, or Singapore Airlines going through their hub cities (Taipei, Beijing, Singapore). That would get us to those cities (normally 40,000+ miles) for just 30,000.

These routings don't show up in the Aeroplan search results, but are they even possible? Could I stitch together something like YYZ-DEL-FCO or YVR-PEK-ATH and then call the Aeroplan contact center to make it happen? Or is there some rule that would prevent these trips from working at all? Thanks.
