here is an hypotical situation lets say a forgein carrier flying from DFW to London and they have a medical emergency around Chicago to make an emergency landing at ORD they have to dump fuel, but this particular airline doesn't not any facilities at ORD,. my question is after the emergency is over, the plane will need fuel so they can continue the flight to London how can airline get the fuel for the aircraft? (I would assume the local fueler would bill that airline)
