What Makes ATL So Busy
Hartsfield-Jackson Atlanta International Airport (ATL) is the beating heart of air travel in the United States — and for good reason. With its central location, massive infrastructure, and role as a Delta Air Lines hub, it sees more passengers each year than any other airport in the world. But with great volume comes great responsibility… and sometimes, great waiting — especially when it comes to TSA lines.
Whether you’re a seasoned jet-setter or flying for the first time, understanding the TSA wait times at ATL is key to a smooth journey. This guide offers insight, tips, and tools to help you minimize time spent in line and maximize time enjoying your trip.
🛫 What Makes ATL So Busy?
ATL isn’t just any airport. On average, it sees 275,000+ passengers daily, thanks to:
- Over 200 domestic and international gates
- Major airline hubs (especially Delta)
- Connecting flights linking East Coast and West Coast travel
With this level of traffic, security lines can fluctuate wildly depending on the time of day, season, and even current events.
