All pages: https://atlairportguide.com/llms.txt # Getting to ATL for a 6 a.m. flight: the road, MARTA and checkpoint hours ATL's Main checkpoint is open 24 hours. Here are the road options, the parking and the checkpoint hours for a 4 a.m. arrival. Published November 15, 2026 ![The blue entrance canopy of the North economy lot at Atlanta airport, with a SkyTrain car on the raised guideway above it.](https://atlairportguide.com/images/atl/north-daily-deck-predawn-v15.webp) The North Economy parking entrance at Atlanta airport [Every way into town, compared](https://atlairportguide.com/to/): Pick where you are going: time, cost, and the first and last departure for each way. For a 6 a.m. flight, ATL recommends at least two hours before a domestic departure, which means 4 a.m. Check MARTA’s Red and Gold line timetables for the first train to Airport Station before you count on rail, and plan a car or ride if it arrives after 4 a.m. ## MARTA: check the first train against 4 a.m. MARTA’s Red and Gold line timetables give the first train to Airport Station. Our [MARTA page](https://atlairportguide.com/transport/marta-rail/) has the fare: $2.50 standard, with up to four free transfers within three hours. ## By car or ride: book the ride, pick the deck ATL’s maps page puts the airport approximately 20 minutes south of downtown Atlanta during normal traffic. ATL’s security page says the busiest screening times usually fall between 5 a.m. and 9 a.m., so if you arrive at 4 a.m., you’re ahead of that window. Our [directions guide](https://atlairportguide.com/guides/where-atlanta-airport-address-county-directions/) has ATL’s driving routes. Uber’s page says you can reserve a ride up to 90 days ahead and cancel for free until one hour before pickup. It lists an average UberX fare from Old Fourth Ward to ATL over the past month and says that isn’t a fixed price. If you park, ATL’s parking page prices the [ATL West Deck](https://atlairportguide.com/parking/atl-west-parking-deck/) at $30 a day. It calls the deck a 3-5 minute SkyTrain ride from check-in and arrivals and says the SkyTrain boards on Level 4. ATL says the SkyTrain runs 24 hours a day. [Park Ride Lot C](https://atlairportguide.com/parking/park-ride-lot-c/) runs on a shuttle instead, and ATL’s parking page prints no shuttle hours for it. To skip the early drive, our [hotels page](https://atlairportguide.com/hotels/) lists which airport hotels reach the terminal by train and which by shuttle. ## Which checkpoint is open at 4 a.m. ATL lists these hours on its passenger security page. Passengers can reach every concourse and gate from any checkpoint. | Checkpoint | Lanes ATL lists | Hours | | --- | --- | --- | | Domestic Terminal Main | Standard screening | 24 hours | | Domestic Terminal Lower North | Standard screening, CLEAR standard | 3:30 a.m. to 9:00 p.m. | | Domestic Terminal North | Standard screening, priority screening | 4:00 a.m. to 9:00 p.m. | | Domestic Terminal South | TSA PreCheck, PreCheck Touchless ID, CLEAR with PreCheck | 4:00 a.m. to 9:00 p.m. | | International Terminal Departures | Standard screening, TSA PreCheck | Standard 4:30 a.m. to midnight. PreCheck 7:00 to 10:00 a.m. and 2:00 to 7:00 p.m. | ATL’s 3:30 a.m. to 9:00 p.m. at Lower North is the checkpoint’s hours, with CLEAR standard among its lanes. CLEAR’s own page lists its standard lane on the lower level of the North side from 4:30 a.m. to 7:30 p.m. So the checkpoint opens first, and if CLEAR is your lane and you arrive at 4 a.m., plan on the CLEAR lane opening at 4:30. Our [security page](https://atlairportguide.com/security/) lists each checkpoint with its hours and PreCheck lanes. Your airline sets its own bag-drop cutoff, since ATL’s pages don’t give one. Our [airlines page](https://atlairportguide.com/airlines/) shows where each airline checks in. ### Sources - Our [MARTA page](https://atlairportguide.com/transport/marta-rail/), [security page](https://atlairportguide.com/security/), [hotels page](https://atlairportguide.com/hotels/), [airlines page](https://atlairportguide.com/airlines/), [ATL West Deck listing](https://atlairportguide.com/parking/atl-west-parking-deck/) and [Park Ride Lot C listing](https://atlairportguide.com/parking/park-ride-lot-c/) - Our [directions guide](https://atlairportguide.com/guides/where-atlanta-airport-address-county-directions/) - MARTA’s Red line timetable and Gold line timetable - ATL’s passenger security page - ATL’s parking page - ATL’s ground transportation page - ATL’s terminal maps and directions page - Uber’s Atlanta airport page - CLEAR’s Hartsfield-Jackson page
