Book Cheap Flights to Atlanta Compare & Book Affordable Airfare

The cheapest months to fly to Atlanta are January and February. Demand for travel after the holidays slows considerably, and airlines lower their ticket prices. Those who aren't averse to cooler weather (Atlanta winters are mild by comparison to most places across the country, usually in the 40s–50s°F) will find great bargains on flights and hotels during this period.

In contrast, spring and summer are the busiest times of the year for flying. Atlanta's event calendar is packed in the summer months, with prices remaining high from May to August, and March and April experience a lot of traffic during spring break. Fares also spike in the fall, especially during the college football season and late November and December, when people travel for the holidays. During these busy times, flights from northern destinations, such as New York, Chicago, and Boston, can be 40–70% higher than normal.

Hartsfield-Jackson Atlanta International Airport (ATL) is one of the busiest airports in the world, with over 100 million passengers using the airport each year, with flight paths to hundreds of international and domestic locations. The primary Airlines flying in and out of Atlanta Airport are:

Delta Air Lines:

• Carry-on and personal bags included (Main Cabin); personal item only on Basic Economy fares
• Since Atlanta (ATL) is their primary hub, Delta offers the most flight options whether domestic or international. ATL gives members with SkyMiles benefits the most flexibility when planning travel.

Southwest Airlines:

• Two checked bags are allowed at no cost with all fare types, and no fees for changes or cancellations
• Provides significant coverage of routes throughout the Southeast, the Midwest and beyond from a very affordable starting price from ATL to a wide range of cities across the US.

American Airlines:

• Carry-on and personal bags included (Main Cabin); personal item only on Basic Economy fares
• Connect through any hub (Charlotte, Miami, Dallas, etc.) as well as offer good direct options to some locations in the NE, if you don't mind a slightly more complex travel plan.

Spirit Airlines:

• Base fares are low, with extras (checked bags, carry-ons, seat assignment) added for an additional cost
• The perfect carrier if you plan on traveling light, since Spirit has some of the lowest ticket prices available (if you pay for only what you need).

United Airlines:

• Carry-on and personal bags included (Economy); personal item only on Basic Economy fares
• Reliable and convenient option for those travelers planning to connect through Houston, Chicago, or Denver airports before reaching their final destination.

ATL's size means it attracts a wide range of carriers, including ultra-low-cost airlines like Spirit and Frontier that use unbundled pricing. The advertised base fare may cover only your seat - bags, seat selection, and priority boarding are each charged separately and can push a "cheap" ticket well past the price of a mainstream carrier.

Before you click to book, you may want to consider whether or not:

• An overhead carry-on or only an under-seat personal item is permitted with your fare.
• The size and weight limits for personal items: oversized bags found at the gate are typically charged the highest checked bag rate.
• The ticket is refundable or changeable. Most Basic Economy and ultra-low-cost fares are neither.
• Resort fees, parking, or rental car insurance have been pre-bundled into any package you are considering.
