Air travel is generally safe, but the flight environment poses unique physiologic challenges such as relative hypoxia that may trigger adverse myocardial or pulmonary outcomes. To optimize health outcomes, communication must take place between the traveler, family physician, and airline carrier when there is any doubt about fitness for air travel. Travelers should carry current medications in their original containers and a list of their medical conditions and allergies; they should adjust timing of medications as needed based on time zone changes. The Hypoxia Altitude Simulation Test can be used to determine specific in-flight oxygen requirements for patients who have pulmonary complications or for those for whom safe air travel remains in doubt. Patients with pulmonary conditions who are unable to walk 50 m or for those whose usual oxygen requirements exceed 4 L per minute should be advised not to fly. Trapped gases that expand at high altitude can cause problems for travelers with recent surgery; casting; ear, nose, and throat issues; or dental issues. Insulin requirements may change based on duration and direction of travel. Travelers can minimize risk for deep venous thrombosis by adequately hydrating, avoiding alcohol, walking for 10 to 15 minutes every two hours of travel time, and performing seated isometric exercises. Wearing compression stockings can prevent asymptomatic deep venous thrombosis and superficial venous thrombosis for flights five hours or longer in duration. Physicians and travelers can review relevant pretravel health information, including required and recommended immunizations, health concerns, and other travel resources appropriate for any destination worldwide on the Centers for Disease Control and Prevention travel website.
Air travel has become increasingly popular over time, despite decreases during the COVID-19 pandemic, with 1.1 billion total passengers in 2019 and most Americans having flown at least once in the past three years.1 Air travel is generally safe, but especially for the aging U.S. population, the flight environment poses unique physiologic challenges, particularly relative hypoxia, which may trigger adverse myocardial or pulmonary outcomes. To optimize health outcomes, communication must take place between the traveler, family physician, and airline carrier when any doubt occurs about fitness for air travel. Travelers should carry current medications in their original containers as well as a list of their medical conditions and allergies and should adjust timing of medications as needed based on time zone changes. Travelers should also consider available medical resources at their travel destinations and layover locations. Family physicians and travelers can review relevant pretravel health information, including required and recommended immunizations, health concerns, and other travel resources appropriate for any destination worldwide at https://wwwnc.cdc.gov/travel/destinations/list.
