If you travel by air frequently, and your busy schedule has so far this season prevented you from getting a flu shot, check out your next airport stop. Many major ones now offer in-station medical facilities, including quick flu shots.

As of this writing, they include Las Vegas, San Francisco, Los Angeles, Cleveland, Chicago O’Hare and Nashville. In the New York City area, clinics are available at JFK and Newark. Other airports may also have or plan to offer the service in the future.

To protect yourself, especially during the heavy air traffic holiday season and winter, allow the extra time for the service. When you arrive at the airport, ask security where you can get your flu shot. Costs per shot can be as much as $50, or free for those with in-effect proof of insurance coverage.
