TSA's New ‘One Stop Security’ Service Simplifies Airport Connections From Europe to the US | Condé Nast Traveler

"On Delta’s London–Atlanta service (flight 5999), checked bags are screened overseas through International Remote Baggage Screening and forwarded directly to final destinations so I no longer need to reclaim and recheck them, which the airline says can save up to about 40 minutes; however, bypassing the second security checkpoint under Delta’s procedures requires that connecting customers have Global Entry or use the Mobile Passport Control app (available to US citizens and permanent residents)." - Jessica Puckett
