This route lands a B, about a point worse than the national rate of 77.3%. About one flight in four arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That rests on 2,080 DFW to HSV flights, of which Envoy Air flew 1,083 at 83.2% on time.
Best time to fly DFW to HSV: a 5am–8am departure, ideally on a Tuesday. Flights in that window arrived on time 85.8% of the time and Tuesday flights 82.0%, against 76.5% for the route overall.
The US average over the same twelve months is 77.3%, so there is little to separate this route from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
Which airline is most reliable on DFW to HSV
The choice of carrier is not cosmetic here. Envoy Air arrives on time 83.2% of the time; PSA Airlines manages 73.6%. Sample sizes sit next to every figure, because a two-point gap across 738 flights means less than a ten-point one.

| SkyWest Airlinesthin sample | 72 | 85.9% | 76 min | 1.39% | A |

| American Airlinesthin sample | 187 | 44.8% | 108 min | 3.21% | F− |
PSA Airlines cancels 4.5% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

Best ways to make this trip
The most reliable ways to fly Dallas-Fort Worth to Huntsville
Every airline on this route, ranked by how often a scheduled flight actually operated and arrived on time, with its best departure time and most punctual flight number. No nearby airport pair beat these.
| Option | Airline | Success | On time | Cancelled | Best departure | Most punctual flight |
|---|---|---|---|---|---|---|
| 1. DFW → HSVDallas-Fort Worth to Huntsville | Envoy Air | 81.7% | 83.2% | 1.75% | 5am–8am, Tue | — |
| 2. DFW → HSVDallas-Fort Worth to Huntsville | PSA Airlines | 70.3% | 73.6% | 4.47% | 2pm–5pm, Tue | — |
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 24 points, against 10 points between the best and worst carrier.

Scale runs 55% to 90%.
The 8pm–5am window is where this operation falls apart: 61.5% on time, against 85.8% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 5pm–8pm window is the busiest, with 502 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 16 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 March, when the on-time rate falls to 71.2%. February is the strongest month at 87.5%. Moving a flexible trip across that boundary buys 16 points. July was the busiest month here, with 206 flights.
Across the week, Tuesday is the strongest day at 82.0% on time and Sunday the weakest at 69.6%, a spread of 12 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 53% of the 39,000 delay minutes carriers reported here, and the remaining four split what is left.
- 53%Late-arriving aircraft
- 27%Carrier
- 11%National Airspace System
- 8%Extreme weather
- 0%Security
53% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 39,000 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 39,323 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 85.8% on time here.
Cancellations run at 2.84%, against 1.89% nationally. That is roughly 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
10.2% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 603 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The return leg runs 78.8% on time across 2,079 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 2,080 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 delay figures matter less here than the 2.84% cancellation rate. A late arrival costs you an hour and a half; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 2,015 completed flights over 12 months sit behind that.
Common questions
DFW to HSV questions
How often is DFW to HSV delayed?
About one flight in four arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 23.5% of the 2,080 flights in this analysis, against 22.7% nationally. Delayed flights are late by an hour and a half on average.
Which airline is most reliable on DFW to HSV?
Envoy Air leads at 83.2% on time across 1,083 flights. PSA Airlines is at the other end on 73.6%, a gap of 10 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.
What time of day has the fewest delays on DFW to HSV?
The 5am–8am departure window is the strongest at 85.8% on time. The 8pm–5am window is the weakest at 61.5%, 24 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 March delays on DFW to HSV?
March is the weakest month at 71.2% on time, compared with 87.5% in February. Across the year that is 16 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
