However, the Association has received reports from several travelers which suggest that there is a new TSA policy subjecting all pump-wearers to additional screening. Specifically, on multiple occasions when TSA personnel have become aware that a traveler uses an insulin pump, they have done a comprehensive hand and explosive check of all of the traveler’s carry-on baggage, not just medical supplies. In light of these reports, we recommend that you allow extra time to be processed through airport security if you wear an insulin pump.
