What is the pattern of releasing award tickets in Y? I'm trying HKG-YYZ for June 2018 but only 2 days in the month have Y availability (one of the days has 7+ tickets, the other has unspecified number of tickets). Will more Y tickets be released sometime down the line?
Also, just wanted to confirm that NRT-HKG-YYZ is allowed as a one-way for 30,000 miles despite a little bit of backtracking?
