YYZ-UVF is one of those ephemeral "direct" flights - two sectors with one flight number. Anyway, it goes away in early June, never to reappear on the timetable.

For tier points, note that AA books D into A on two-class US domestic flights, but US-Canada and US-Caribbean/Latin American flights don't offer first class, so while LAX-YYZ-MIA would earn 160 TP (120+40), LAX-MIA-YYZ would earn 220 (180+40 if LAX-MIA is flown in a 2-class plane such as a 757.)
