Viewed through the grid of Concourse A’s vast curtain-wall windows, a Delta Air Lines jet sits at the gate at Detroit Metro Airport, undergoing final preparations before departure. Ground crews maneuver baggage carts and service vehicles along the concrete apron beneath the overcast Michigan sky. The McNamara Terminal’s panoramic windows reveal the precision and coordination of modern aviation — a quiet balance of machinery, logistics, and architecture that defines one of America’s most important airline hubs.

Inside Concourse A of Detroit Metropolitan Wayne County Airport (DTW), travelers move through the main corridor of the McNamara Terminal, a hub designed around Delta Air Lines operations. The terminal’s mile-long concourse, opened in 2002, features the elevated red ExpressTram gliding silently above the concourse, linking distant gates in under two minutes. Glass storefronts, high ceilings, and modern lighting reflect DTW’s role as one of the most efficient and architecturally forward airports in North America. The photo captures the rhythm of early-morning movement — passengers, luggage, and signage converging under the massive steel-truss ceiling.
