Answer 1

Money, jet fuel is far more expensive than the fuel for the little tug.

I build products for airlines on the Tarmac. We have a complete system of hoses that run from H/Vac units under the bridge to the airplane because it is too expensive to run the onboard climate control off the jet fuel.
