Real world fueling question (Southwest)

[leinsters]

Let's say a Southwest jet has a planned five takeoffs and landings.in a given day. Does the company essentially fill-up the tanks to accommodate as many flights as possible, thus saving turnaround time on the ground? Or does it fill up on the ground for each flight?

Thanks,

Len

Hi Len, Uplift fuel each flight unless the fuel is very expensive down route, in which case you could tanker fuel for a round trip if able. The main reason is it costs money to carry the extra fuel, for example on my real world flight today we would burn an extra 7kgs of fuel for every 100kgs of extra fuel we carried.

In europe you have expensive fuel prices on the isles so mostly you'll fill up for the backflight but rarely on short flights or within cities.
