Moving away briefly from the issue of contaminated runways (which don't necessarily apply in the OP's scenario), just a reminder of the two possible incentives for
considering tankering in the first place:
1) problems with fuel availability at the first destination;
2) fuel more costly at the first destination than at the originating airfield.
In (2), the cost of carrying the fuel must be taken into account. Issues such as extra wear and tear on the engines, brakes and airframe are tough to quantify. Whether the increased fuel burn on the first sector negates the gain from the price difference can easily be settled, as I commented in an
earlier post, using a graph of cost-difference versus sector-time (nowadays performed by computer).
