Security and boarding at the Delta Airlines PHL Terminal are handled efficiently, giving travelers peace of mind. Check-in begins in Terminal D with multiple self-service kiosks and staffed counters for those checking bags or needing assistance. Delta’s mobile app also allows passengers to check in ahead of time and receive mobile boarding passes, speeding up the process. Security lines in Terminal D are generally well-organized, with TSA PreCheck lanes available for eligible travelers. Once past security, passengers can access their gates quickly due to the compact, easy-to-navigate layout.
