I don't know exactly which airports these may be, but airports often share runways with military bases, especially ANG bases. I sat on a plane waiting for takeoff before while watching several F-16s take off in front of us. It is also similar to how many big airports have areas for UPS or Fedex away from the passenger side. Lots of room in those areas for jets to just sit if they need to.
It is possible that the USSS asks the Trump people to park on the military side (if there is one at that airport) so the plane is safe and not in the way of commercial transportation during his rallies.
