San Diego Terminal 1 Debuts; Dublin Adopts CT Scanners
San Diego Terminal 1 opened on September 29, 2025, while Dublin Airport upgraded security with CT scanners to speed screenings.
San Diego Terminal 1 (SAN) officially opened on September 29, 2025, marking the completion of phase one of a $3.8 billion project to replace the 58‑year‑old terminal. The new facility adds 19 gates, expanded security lanes and more retail and dining space, prioritizing a smoother passenger flow and modern amenities for travelers in Southern California.
San Diego Terminal 1: what changed
The rebuild is designed to handle increased demand and improve connections across the airport. Terminal 1’s refreshed layout shortens walking distances, adds contemporary concessions, and expands security screening capacity — all intended to reduce delays and improve the passenger experience at SAN.
Across the Atlantic, Dublin Airport (DUB) has introduced 30 new CT (computed tomography) scanners at departing security checkpoints. These machines allow passengers to keep liquids and electronics inside their carry‑on bags and permit up to 2 liters of liquids, easing the previous 100 ml restriction and accelerating the screening process for many travelers.
- San Diego Terminal 1: opened Sept. 29, 2025; 19 gates; $3.8B first phase to replace a 58‑year‑old terminal.
- Dublin Airport (DUB): deployed 30 CT scanners, permits up to 2 liters of liquids and keeps electronics in bags.
- Passenger impact: faster throughput, fewer bag checks, and reduced need to unpack at checkpoints.
Both moves reflect a wider airport trend toward investment in passenger convenience and advanced screening technology. San Diego’s investment focuses on capacity and comfort, while Dublin’s CT rollout emphasizes security modernization and throughput gains. Together, they show how airports are balancing infrastructure upgrades with technology to make travel less stressful.
For travelers flying through SAN or DUB, expect quieter lines and less unpacking at security — and a clear sign that airports continue to prioritize speed and safety as passenger volumes climb back to pre‑pandemic levels.
