Flight delays at Atlanta Hartsfield-Jackson ATL

Why flights get delayed at ATL

Summer thunderstorms

Afternoon and evening storms from late spring through September regularly slow arrivals and stop ramp work while lightning is nearby.

Sheer volume

Atlanta handles more passengers than any other airport in the world. When the schedule is that full, a one-hour weather stop takes many hours to clear.

Hub knock-on effects

Most flights here are part of Delta connecting banks, so a late inbound aircraft or crew often becomes a late departure.

Flying through ATL soon? How to prepare

• Time it well.
• Know your airline's commitments. Check what Delta Air Lines or your own airline has promised for delays and cancellations in our airline policy guides, or see how to check it yourself.
• Line up a backup. Note the next couple of flights on your route and the alternate airports below before you leave home.
• Connecting here? Keep both flights on one ticket and choose a layover with room to spare above the minimum connection time.

If your flight is delayed or cancelled at ATL

1. Find the real cause. Ask the gate agent, then compare it with the FAA status above. The cause decides what the airline owes you: see is it really a weather delay?
2. Know your refund right. If the flight is cancelled, or delayed three hours or more (six for international), you can decline to travel and get your money back.
3. Line up alternatives first. Look at later flights, other airlines and the alternate airports below before you reach the desk.
4. Ask for what the airline has committed to. For delays within its control, that usually means a meal after three hours and a hotel overnight. Here is what to say.
