Atlanta (ATL) and Orlando (MCO): July 2026 on-time record

The two directions together ran behind the national figure in July 2026, with 57.8% of the 1,387 flights between Atlanta and Orlando arriving on time against a national share of 69.4% across all 630,535 reported flights. That leaves the pair on the weaker side of the national picture.

This pair was dominated by one operator: Delta Air Lines alone flew 69.8% of all flights, more than half.

Delta Air Lines came out clearly on top: it had the highest on-time share in both directions, and each lead over the next airline was large enough to separate in one month of data. This is the one airline whose edge the figures support.

Late-arriving aircraft led the delay minutes BTS attributed to flights between Atlanta and Orlando, with 43.1% of the total, the same picture as the national total for July 2026.

One direction trailed a little. Flights from Atlanta to Orlando ran on time less often, 54.5% of 694 against 61.0% of 693 the other way, a gap under 10 points that one month of data can still separate.

2 airlines flew this pair often enough to be ranked in at least one direction. Each is set against the pair's combined figure below, so the comparison is among a small field.

Delta Air Lines dominated this pair, flying more than half of all its flights, 968 in all, and 60.3% of them arrived on time, level with the pair's combined 57.8%, give or take a few points. Every other airline here was a junior partner.

Frontier Airlines operated 235 of the pair's flights; 47.2% were on time, behind the pair's combined 57.8%.

Also flew this pair, too few flights to rank: Southwest Airlines (184 flights).

Of the 33 routes out of ATL that carried at least 300 flights in July 2026, the route to MCO placed in the bottom third for on-time arrivals.

Of the 15 routes out of MCO that carried at least 300 flights in July 2026, the route to ATL placed in the middle third for on-time arrivals.

Late-arriving aircraft led in both directions, on flights out of Atlanta and on flights out of Orlando alike.

With late-arriving aircraft the largest cause, extreme weather added 4.0% of the attributed minutes for flights between Atlanta and Orlando, close to its national share of 6.4%.

Behind the late-arriving aircraft figure, air carrier and NAS delays ran level for flights between Atlanta and Orlando, 25.9% against 27.0% of the attributed minutes, unlike the national figures.

Late-arriving aircraft supplied 43.1% of the attributed delay minutes for flights between Atlanta and Orlando, a clear lead but short of a near-majority, with the rest spread over the other causes.

The National Aviation System ranked second for flights between Atlanta and Orlando, with 27.0% of the attributed delay minutes.

Delay causes are shares of the delay minutes BTS attributes to flights that arrived 15 minutes or more late, not shares of flights. Extreme weather here means BTS's extreme-weather category only; milder weather delays are generally reported under NAS.

A flight counts as on time unless it arrives 15 minutes or more late. Cancelled and diverted flights count as not on time.

Directions are shown only with at least 500 flights, and an airline is ranked only with at least 100 flights in a direction; airlines below that are listed by name, not ranked.

A difference of a few points between two airlines, or between two directions, is within what one month of data can move. These figures describe July 2026 only.

These are figures for one month, July 2026, not a trend or forecast.
