YYZ- YVR is a stretch for an MD-83. To fly to YVR, it typically needs 3000 lbs short of full fuel. That's less than 1.5 tons, in other words nothing. We fill them often to 41, 500 lbs. That's 9,500 in each wing (full), both aux tanks at 2500 (full) and 18,000 in the center ( 3000 short of full).
1,5 tons short of full fuel means a lot of bags often get left out in the curb, as do pax and while that happens... long delays, of up to an hour. That's unnacceptable, especially due to the fact that it is unavoidable every time there's a headwind (always) and a big load.
Given, it's a low- cost. But consider a full AC 320 goes to LAX from YYZ on 14,5 tons of fuel. The high- bypass factor...
