There usually are private air ambulance crews which transfer patients all over the US. As they need to be taken to a new medical facility and are for emergency situations , medflight crews must be used. Family members call for a flight doctor , and/or an IV care setup for narcotics ….. and they are not good to go by your usual airliners. Many elderly men and women who look for help from med flight companies are not US citizens and/or have a medical necessity of being taken to a more proficient hospital. Accredited medevac businesses sometimes are contacted by families of patients without the assistance of a trained hospital case worker.
