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 Brownsville to Dallas-Fort Worth
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 matters more here than the choice of carrier. The gap between the best and worst window is 16 points, against half a point between the best and worst carrier.
- 5am–8am362 flights95.0%
- 8am–11am315 flights91.9%
- 11am–2pm36 flights85.7%
- 2pm–5pm347 flights84.1%
- 5pm–8pm331 flights79.3%
- 8pm–5am30 flights86.7%
Scale runs 70% to 100%.
Book the early departure. Flights leaving between 5am–8am arrive on time 95.0% of the time, against 79.3% for the evening window. That is 16 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 362 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 13 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 79.8%. February is the strongest month at 93.1%. Moving a flexible trip across that boundary buys 13 points. November was the busiest month here, with 126 flights.
Across the week, Tuesday is the strongest day at 92.2% on time and Saturday the weakest at 82.9%, a spread of 9 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 48% of the 14,000 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Late-arriving aircraft
- 23%Extreme weather
- 17%Carrier
- 12%National Airspace System
- 0%Security
Extreme weather accounts for 23% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 3.9 times the usual weather exposure. The split is drawn from 14,012 reported delay minutes.
48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 14,000 reported delay minutes here, that single category outweighs weather by 2 to one.
Cancellations sit at 2.32% against a national 1.89%, which is ordinary. Diversions add another 0.28%.
Connections and stage length
What a delay here actually costs
5.1% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.
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 5am–8am window matters as much as it does.
The return leg runs 85.6% 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 93.1% on time and September 79.8%, a swing of 13 points. If the dates move at all, move them out of September before you think about anything else. 1,384 completed flights over 12 months sit behind that.

The 5am–8am departure window is the strongest at 95.0% on time. The 5pm–8pm window is the weakest at 79.3%, 16 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.
How bad are September delays on BRO to DFW?
