How to save porridge and fish ?

If you have the plane, and your sled is empty, use your plane to go to location and return with your sled.

You fly, if your plane (or sled) is empty, to all stations for ONLY 1 kerosene. For Polar-Side Station, with my sled, the travel use 11 fish to go and 11 fish for return.
