B737-500 -> A220-100ER total expences?

[Flightman]

Cannot understand, why in some airports total expences remain but fuel cost lowers like it should. A220 compared to B737 should be less expensive to operate on all meters?

B735 has MTOW of 52.4tn and A220-100ER is actually a bit heavier at 58.1tn, so the enroute navigation fees and airport landing fees are higher since they are MTOW-related. The ground handling fees about are the same. You can compare these from the airport pages.

but the fuel line has a noticeable drop about 10th April so that's good. But this plane is full so time for a bigger one/HD seats perhaps?
