These figures cover 1,421 flights between September 2025 and August 2026. The median arrival is 11 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.

The most reliable ways to fly Dallas-Fort Worth to Brownsville
Every airline on this route and on the routes between nearby airports, ranked by how often a scheduled flight actually operated and arrived on time. 3 of the top 4 use a different airport at one end.

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 is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 1,421 flights.

Book the morning departure. Flights leaving between 8am–11am arrive on time 91.0% of the time, against 81.4% for the evening window. That is 10 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8pm–5am window is the busiest, with 354 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 14 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
Delays peak in September, when the on-time rate falls to 80.7%. February is the strongest month at 95.1%. Moving a flexible trip across that boundary buys 14 points. November was the busiest month here, with 126 flights.
Across the week, Thursday is the strongest day at 91.4% on time and Wednesday the weakest at 82.1%, a spread of 9 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 48% of the 11,000 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Late-arriving aircraft
- 25%Carrier
- 19%National Airspace System
- 8%Extreme weather
48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 11,000 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 10,571 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 91.0% on time here.
Cancellations sit at 2.32% against a national 1.89%, which is ordinary. Diversions add another 0.14%.
Connections and stage length
What a delay here actually costs
Badly late arrivals are rare here: only 4.2% 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 482 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 8am–11am window matters as much as it does.
The return leg runs 87.6% on time across 1,421 flights, within 2 points 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 1,421 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: the calendar is the biggest lever here, not the carrier or the hour. February runs 95.1% on time and September 80.7%, a swing of 14 points. If the dates move at all, move them out of September before you think about anything else. 1,386 completed flights over 12 months sit behind that.

The 8am–11am departure window is the strongest at 91.0% on time. The 5pm–8pm window is the weakest at 81.4%, 10 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.
