Delta's CEO has been among the insistent whiners about the "hassle factor" from increased security costing the airlines revenue. Heck, with one exception in the last year, I haven't spent more than five minutes in a security line. Check-in lines, however, have consistently gotten longer as more people need to check bags (carry on restrictions) and airlines have cut counter staffing. Fly through DTW and admire the presence of one NWA agent and 17 open positions - serving the WP Elite line.
This may be one area where Delta "gets it."
