These figures cover 2,596 flights between September 2025 and August 2026. The median arrival is 9 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Success is the share of scheduled flights that operated and arrived less than 15 minutes late, so a cancelled flight counts against it. “(route)” means the best time comes from every carrier on the route rather than this airline alone.
Departure window
The best time of day to leave
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 21 points, against half a point between the best and worst carrier.

- 8am–11am526 flights93.9%
- 11am–2pm452 flights88.0%

- 5pm–8pm530 flights77.9%
- 8pm–5am196 flights73.5%
Scale runs 65% to 100%.
Book the early departure. Flights leaving between 5am–8am arrive on time 94.6% of the time, against 73.5% for the overnight window. That is 21 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5pm–8pm window is the busiest, with 530 flights scheduled in it.

Across the year
When delays peak on this route
Twelve months, one bar each, drawn from the same 2,596 flights. The strip shows how much of this route's record is set by the calendar rather than by the operation.
Delays peak in May, when the on-time rate falls to 79.9%. February is the strongest month at 90.9%. Moving a flexible trip across that boundary buys 11 points. October was the busiest month here, with 242 flights.
Across the week, Tuesday is the strongest day at 90.4% on time and Sunday the weakest at 79.6%, a spread of 11 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 67% of the 20,000 delay minutes carriers reported here, and the remaining four split what is left.
- 67%Late-arriving aircraft
- 19%Carrier
- 12%National Airspace System
- 1%Extreme weather
- 1%Security
67% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 20,000 reported delay minutes here, that single category outweighs weather by 64 to one. The split is drawn from 19,557 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 94.6% on time here.
Cancellations sit at 1.66% against a national 1.89%, which is ordinary. Diversions add another 0.39%.
Connections and stage length
What a delay here actually costs
Badly late arrivals are rare here: only 4.0% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
At 358 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 5am–8am window matters as much as it does.
The return leg runs 86.5% on time across 2,596 flights, within about a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
The sample behind these figures is 2,596 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this
Booking this route
Put together: avoid the 8pm–5am departure. It runs 73.5% on time against 94.6% for the 5am–8am slot, and that 21 points is the largest single thing you control here. Southwest Airlines is the strongest operator if the fares are close. 2,543 completed flights over 12 months sit behind that.

The 5am–8am departure window is the strongest at 94.6% on time. The 8pm–5am window is the weakest at 73.5%, 21 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
