This route earns an A. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.3%. When something does go wrong the average delay runs close to two hours. That rests on 1,480 HRL to DFW flights, with a median arrival 9 minutes early.
Best time to fly HRL to DFW: a 8am–11am departure, ideally on a Thursday. Flights in that window arrived on time 90.5% of the time and Thursday flights 90.9%, against 86.8% for the route overall.
Set against the rest of the country, this route's record is 10 points better than the US average of 77.3%. That gap is worth roughly 95 fewer late arrivals for every thousand flights.

These figures cover 1,480 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.

Best ways to make this trip
The most reliable ways to fly Harlingen 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 11 points, against half a point between the best and worst carrier.
- 5am–8am364 flights90.2%
- 8am–11am328 flights90.5%
- 11am–2pm81 flights87.3%
- 2pm–5pm279 flights84.7%
- 5pm–8pm252 flights79.7%
- 8pm–5am176 flights86.3%
Scale runs 70% to 95%.
Book the morning departure. Flights leaving between 8am–11am arrive on time 90.5% of the time, against 79.7% for the evening window. That is 11 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 364 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 November, when the on-time rate falls to 80.7%. February is the strongest month at 94.5%. Moving a flexible trip across that boundary buys 14 points. November was the busiest month here, with 144 flights.
Across the week, Thursday is the strongest day at 90.9% on time and Saturday the weakest at 80.9%, a spread of 10 points.
Delay causes
Why this route gets delayed
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 20,000 reported delay minutes.
- 40%Late-arriving aircraft
- 26%Carrier
- 22%National Airspace System
- 11%Extreme weather
- 0%Security
Extreme weather accounts for 11% 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 1.9 times the usual weather exposure. The split is drawn from 19,612 reported delay minutes.
40% 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 4 to one.
Cancellations run at 2.64%, against 1.89% nationally. That is about one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and stage length
What a delay here actually costs
6.6% 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 close to two hours, which a normal layover absorbs.
At 461 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 85.4% on time across 1,480 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 1,480 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 94.5% on time and November 80.7%, a swing of 14 points. If the dates move at all, move them out of November before you think about anything else. 1,437 completed flights over 12 months sit behind that.
Common questions
HRL to DFW questions
How often is HRL to DFW delayed?
About one flight in eight arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 13.2% of the 1,480 flights in this analysis, against 22.7% nationally. Delayed flights are late by close to two hours on average.
How reliable is HRL to DFW compared with the rest of the country?
86.8% of flights arrive on time here against a national 77.3%, a difference of 10 points in its favour. That is worth a A on this site's grading scale.
What time of day has the fewest delays on HRL to DFW?
The 8am–11am departure window is the strongest at 90.5% on time. The 5pm–8pm window is the weakest at 79.7%, 11 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 November delays on HRL to DFW?
November is the weakest month at 80.7% on time, compared with 94.5% in February. Across the year that is 14 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
