All of these factors can affect your diabetes control: the routine hassle and stress of travel; changes in time zones, schedules, and activity levels; and unpredictable meal times and types of food. Be extra attentive to monitoring your glucose frequently, and be prepared to respond if needed.
Our tips on flying and airport security guidelines apply to travel within the United States. These tips are subject to change, so please also check with the Transportation Security Administration (TSA). International passengers should consult their individual air carriers for international regulations.
Insulin pumps and blood glucose meters
Manually check your glucose levels using a blood glucose meter.
Personal CGM
If you wear a CGM device, it is safe for use on U.S. commercial airlines. If questioned by airline personnel about the use of your device, please show them your Airport Information Card. If they still request that you turn off your CGM device, you must comply.
If you are asked to turn off your CGM device, you will have a "data gap" when uploading data into CareLink™ Personal Software, where information is missing from the period of time when your CGM system was turned off.
