Airborne telemedicine

As airlines upgrade their in-flight Wi-Fi systems, they often tout the passenger experience benefits, like faster internet browsing or better entertainment options. But some see another advantage: Easier communication with medical experts on the ground when a passenger is sick or injured — and potentially one day, true airborne telemedicine service. About 11 of every 100,000 flights are diverted because of in-flight medical emergencies, per one 2021 study, costing airlines anywhere from $15,000-$893,000 per incident. While flight crews have first-aid training and aircraft carry some basic medical equipment and medications, easier access to fully-trained experts could save lives — and maybe reduce the need for diversions that are both expensive for airlines and a headache for travelers. Delta Air Lines and others have partnered with MedAire, which provides on-demand medical advice to flight crews, among other services. Delta flight attendants can connect with MedAire's medical experts via voice or text directly on their company-issued mobile device, using on-board Wi-Fi. That simplifies and quickens the process compared to the old days of using satellite phones and passing messages back and forth with pilots, who are ultimately responsible for passengers' safety and make the call on whether to divert.
