This is a unique air ambulance alternative which provides bedside to bedside non-emergency medical transport services with patients accompanied by an experienced RN flight nurse on commercial airlines. Flying Angels tailors the transport to the patient and also works with insurance companies. While not free, it is generally much less expensive than traditional air ambulance and could be a good alternative in some situations. Click here to read some case examples.
