This route lands a B−, 2 points better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by close to two hours on average. That rests on 2,079 HSV to DFW flights, of which Envoy Air flew 1,081 at 80.2% on time.
Best time to fly HSV to DFW: a 8am–11am departure, ideally on a Tuesday. Flights in that window arrived on time 84.0% of the time and Tuesday flights 83.8%, against 78.8% 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 HSV to DFW
The two carriers here are closely matched: 3 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| SkyWest Airlinesthin sample | 73 | 81.7% | 280 min | 2.74% | B |
| Envoy Air | 1,081 | 80.2% | 79 min | 1.85% | B |

| American Airlinesthin sample | 188 | 76.8% | 116 min | 3.72% | B− |
PSA Airlines cancels 4.9% 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 Huntsville to Dallas-Fort Worth
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. HSV → DFWHuntsville to Dallas-Fort Worth | Envoy Air | 78.7% | 80.2% | 1.85% | 5am–8am, Tue | — |
| 2. HSV → DFWHuntsville to Dallas-Fort Worth | PSA Airlines | 73.1% | 76.9% | 4.88% | 5am–8am, Fri | — |
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 2,079 flights.

- 8am–11am358 flights84.0%

Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 84.0% of the time, against 74.1% 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 5am–8am window is the busiest, with 686 flights scheduled in it.

Across the year
When delays peak on this route
Twelve months, one bar each, drawn from the same 2,079 flights. The strip shows how much of this route's record is set by the calendar rather than by the operation.
December is the weak month at 72.4% on time, against 83.0% in August. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. July was the busiest month here, with 206 flights.
Across the week, Tuesday is the strongest day at 83.8% on time and Sunday the weakest at 71.4%, a spread of 12 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 43% of the 48,000 delay minutes carriers reported here, and the remaining four split what is left.
- 43%Late-arriving aircraft
- 38%Carrier
- 11%Extreme weather
- 8%National Airspace System
- 0%Security
43% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 48,000 reported delay minutes here, that single category outweighs weather by 4 to one. The split is drawn from 48,326 reported delay minutes.
The largest share of delay minutes, 38%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 18,000 of the 48,000 delay minutes reported here.
Cancellations run at 3.13%, against 1.89% nationally. That is about one flight in 30 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
9.0% 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 76.5% on time across 2,080 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 2,079 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 3.13% cancellation rate. A late arrival costs you close to two hours; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 2,006 completed flights over 12 months sit behind that.
Common questions
HSV to DFW questions
How often is HSV to DFW delayed?
About one flight in five arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 21.2% of the 2,079 flights in this analysis, against 22.7% nationally. Delayed flights are late by close to two hours on average.
Which airline is most reliable on HSV to DFW?
Envoy Air leads at 80.2% on time across 1,081 flights. PSA Airlines is at the other end on 76.9%, a gap of 3 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 HSV to DFW?
The 8am–11am departure window is the strongest at 84.0% on time. The 5pm–8pm window is the weakest at 74.1%, 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.
How bad are December delays on HSV to DFW?
December is the weakest month at 72.4% on time, compared with 83.0% in August. Across the year that is 11 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
