Apologies for a beginner's question, two actually:
- can Openskies (US-Paris) be included in DONE?

- I wish to do this itin:
HKG-xNYC-YUL-NYC-CDG-HKG

I only stated NYC because I wish to use CX nonstop to JFK and directly connect to Montreal where I spend a few days, then a few days in NYC.
Is that a valid itin?
