I do have Precheck, but will be flying internationally out of an A gate next week. I'll also be checking my bag. I can use the bridge (where the "Reserve" service is provided) and avoid the DEN trains. Last month I was in the Precheck queue at DEN for over 30 minutes. I may just give "Reserve" a try. I'll report back.
