Healthcare businesses take off at airports

Pharmacies and walk-in health clinics are opening at more airports across the country, as operators try to capture a sizable portion of travelers and airport employees who want access to basic primary healthcare and to fill their prescriptions at the last minute before traveling. These facilities are common at large foreign airports, but domestic airports have mostly focused on services that cater to travelers' immediate needs. But now several entrepreneurs are betting that there's pent-up demand for such services at airports in the United States.
