Unable to book YZF-YVR-HND, TPE-YYZ
I'm looking to book YZF-YVR (stopover) - HND, TPE-YYZ with ANA miles in J. According to my research it should be an admissible itinerary and cost 92.5K miles. However, I'm getting "This service is not available for the specified itinerary. Please amend the flight criteria and try again." whenever I try to book the flight. Sample dates are 10/22, 12/16 and 12/17. What is the issue with the itinerary? The problem disappears if I change the origin airport from YZF to YYC or YEG. Thanks.
