The longest I've ever spent between the front of the line and the concourse was ~2 minutes. The screening process doesn't need to get shorter, just more parallel. Have more lanes. Hire more staff, and schedule them more evenly. Every time I've waited in an obnoxiously long line, additional lanes were extant but closed. Meanwhile there seemed to be at least 5 staff standing around doing nothing. Have them man a second lane and cut the waiting time in half? There's no inherent reason you can't solve this problem, the limiting factors are just the size of the screening room and the payroll budget.
