Later in April I will be flying commercial air within the states. This will be the first time since I had Medtronic pace makers inserted in my chest to fly. What is the easiest method for advising Southwest that I cannot go through the security gate because metal pacemakers will cause alarm to sound and may shut off the pacemakers. [I] do hAVE ID CARDS FOR EACH PACEMAKER. i CAN NOT BE "wANDED" EITHER AS WAND IS MAGNETIC AND ALSO CCAN SHUT OFF PACEMAKERS. Anyone have suggestions.
