Airport facts

ATL carries 3 routes and 2 airlines in our catalogue, totalling 42 weekly departures. Hartsfield-Jackson Atlanta International Airport (ICAO KATL) serves Atlanta, the United States, in the America/New_York zone (UTC−4 in July). Its coordinates (33.6367, -84.427864) are the basis of every distance on this site.

• IATA: ATL
• ICAO: KATL
• City: Atlanta
• Country: USA
• Time zone: America/New_York
• Coordinates: 33.6367, -84.427864
• Airlines at the airport: 2

Time difference against Mexico City. In July, Atlanta runs 2 h ahead of the Mexican capital (UTC−4 versus UTC−6). In January the airport operates on UTC−5, so the gap is not constant across the year: daylight saving shifts it. This is the calculation that decides whether a pre-booked ground connection still works.

Coordinates, and why we publish them. 33.6367, -84.427864 is the position from which every great-circle distance on this site is computed, including the ones that set the EU261 compensation band. It is not the distance the aircraft flies — that follows airways and diversions — but the geodesic measure the regulations use. Publishing it lets anyone recompute the figures on these pages.

Airlines at ATL

2 catalogued airlines operate routes to or from ATL: 2 full-service and 0 low-cost, with checked allowance from 23 to 25 kg. Alliances present: SkyTeam. They cover 3 catalogued routes and 42 weekly departures. The table below lists each operator with its type, alliance and checked allowance.

Carriers in our catalogue operating routes to or from this airport, with type, alliance and economy baggage allowance:

What US DOT does not cover. The United States has no federal delay compensation: the Department of Transportation regulates refunds — your money back when the airline cancels or significantly changes the flight and you decline the alternative — but it does not require a payout for the hours you lost, the way EU261 does. The single federal exception is involuntary denied boarding from oversales, priced under 14 CFR Part 250; that is a different mechanism from delay and is not triggered by a late departure.

How this list is built. These are the airlines appearing in catalogued routes that touch ATL, not the airport’s full directory: a carrier that flies here but not on a pair we cover does not appear. The type — full-service or low-cost — and the allowance come from our own record for each carrier, and where the datum does not exist we say so rather than filling it with a plausible number.

Routes to Atlanta (ATL)

Our catalogue lists 3 routes into ATL, totalling 42 weekly departures and spanning 1,422 to 2,189 km. The busiest is MEX-ATL at ~24 flights a week; 2 of them carry a cached fare, spread across 1 audience profiles. Every row in this section comes from that same corridor catalogue, not from a live search.

What traffic ATL moves. By audience profile, the routes catalogued here split as: Mexico-US paisano corridor (3). That mix explains the airport’s seasonality: family corridors spike in December and Holy Week, leisure ones follow the holiday calendar, and regional ones stay flatter across the year.

Not all of these routes fly daily. The thinnest on the list is BJX-ATL at ~4 weekly departures — under one a day. On a pair like that a cancellation is not resolved in hours: the next seat may be two or three days out, which is why it is worth avoiding the last flight before a fixed commitment.

Fare seasonality

1 routes at ATL carry a monthly minimum-fare breakdown. Between the cheapest and priciest months observed the gap reaches 15% on the widest route, which shows how much the date matters against the choice of airline at this airport.

Lowest detected fare by month on routes with data, in pesos (MXN). The cheapest versus dearest month helps you time the purchase:

The three peaks of the Mexican calendar. December, Holy Week and summer concentrate family and leisure demand at once, and in those windows price stops responding to normal lead time: cheap buckets sell out earlier and flexible fares go at a premium. Outside them, the usual pattern rewards buying 4 to 8 weeks ahead and travelling midweek. That window is a general Mexican-market rule of thumb, not a measurement of this route: our series records observed prices, not the lead time at which each ticket was bought.

What a ‘cheapest month’ means here. It is the minimum the automated query found for that month — not an average and not a guaranteed fare — and it usually corresponds to the least convenient date combination in the month. A month with no row is not an expensive month: it is a month with no data. With that caveat, the month-to-month comparison still holds because every cell was measured the same way.

Connection tips

ATL concentrates 42 catalogued weekly departures across 2 airlines, in the America/New_York zone. That density is what decides how much slack to leave on a connection: the more of its own services the airline runs here, the more same-day rebooking options exist.

Hartsfield-Jackson Atlanta International Airport runs on the America/New_York time zone; factor the offset from your origin city when planning connections and transfers. The busiest route at ATL is MEX-ATL (~24 flights a week). The lowest fare detected at this airport is $3,876 MXN on the BJX-ATL route. Book 4–8 weeks ahead for the busiest routes to/from Atlanta; fares climb in December, Holy Week and summer. Each route guide above shows month-by-month seasonality and the lowest peso fare. That window is a general Mexican-market rule of thumb, not a measurement of this route: our series records observed prices, not the lead time at which each ticket was bought.

The cheap connection that loses the checked bag. Two separate tickets are not one itinerary: there is no interline agreement, the bag is not checked through to the final destination, and if the first flight lands late the second airline owes you nothing — it sold a different flight. The apparent saving evaporates the moment you buy a same-day replacement. On a single ticket, rebooking and the bag transfer are the carrier’s problem, not yours.

A US layover needs a visa too. The United States has no visa-free international transit: with a Mexican passport you need a B1/B2 or C-1 visa merely to change planes in Houston, Dallas, Miami or Atlanta, even without leaving the terminal. Every US connection forces you through immigration, bag reclaim, customs and re-check. A US-routed itinerary that looks cheaper can therefore be unusable if your visa has expired or is still in process.

Great-circle distance is not the transfer. The figures in the table are geodesic, computed from each airport’s coordinates; the real journey depends on whether road, rail or a domestic flight exists, and on what they cost. An airport 300 km away can be more accessible than one at 120 km if the first has a direct motorway and the second does not. Use them to rule out, not to plan.
