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 an hour and a half on average. That rests on 3,158 OKC to DFW flights, of which Envoy Air flew 1,039 at 80.7% on time.
Best time to fly OKC to DFW: a 5am–8am departure, ideally on a Tuesday. Flights in that window arrived on time 88.4% of the time and Tuesday flights 82.7%, against 79.3% 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 OKC 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.

| SkyWest Airlinesthin sample | 291 | 85.6% | 84 min | 1.72% | A |

No carrier stands out. Envoy tops the table at 80.7%, 3 points clear of the bottom, which is inside the range this kind of sample moves year to year.

Best ways to make this trip
The most reliable ways to fly Oklahoma City 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. OKC → DFWOklahoma City to Dallas-Fort Worth | Envoy Air | 78.7% | 80.7% | 2.50% | 8am–11am, Wed | — |
| 2. OKC → DFWOklahoma City to Dallas-Fort Worth | American Airlines | 76.0% | 78.2% | 2.77% | 5am–8am, Fri | AA 2272 06:00 |
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 23 points, against 3 points between the best and worst carrier.
- 5am–8am794 flights88.4%
- 8am–11am546 flights85.0%
- 11am–2pm470 flights84.4%
- 2pm–5pm560 flights70.9%
- 5pm–8pm577 flights70.5%
- 8pm–5am211 flights65.0%
Scale runs 55% to 95%.
Book the early departure. Flights leaving between 5am–8am arrive on time 88.4% of the time, against 65.0% for the overnight window. That is 23 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 794 flights scheduled in it.

Across the year
When delays peak on this route
Twelve months, one bar each, drawn from the same 3,158 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 73.3% on time, against 84.9% in February. 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 300 flights.
Across the week, Tuesday is the strongest day at 82.7% on time and Sunday the weakest at 74.2%, a spread of 9 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 49% of the 61,000 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Late-arriving aircraft
- 25%Carrier
- 14%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 1.8 times the usual weather exposure. The split is drawn from 61,279 reported delay minutes.
49% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 61,000 reported delay minutes here, that single category outweighs weather by 4 to one.
Cancellations run at 2.63%, 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
9.5% 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.
At 175 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 is a different operation and performs like one: it runs 73.0% on time across 3,158 flights, 6 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 6 points of difference.
The sample behind these figures is 3,158 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: avoid the 8pm–5am departure. It runs 65.0% on time against 88.4% for the 5am–8am slot, and that 23 points is the largest single thing you control here. Envoy Air is the strongest operator if the fares are close. 3,070 completed flights over 12 months sit behind that.
Common questions
OKC to DFW questions
How often is OKC 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 20.7% of the 3,158 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 OKC to DFW?
Envoy Air leads at 80.7% on time across 1,039 flights. American Airlines is at the other end on 78.2%, 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 OKC to DFW?
The 5am–8am departure window is the strongest at 88.4% on time. The 8pm–5am window is the weakest at 65.0%, 23 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 OKC to DFW?
December is the weakest month at 73.3% on time, compared with 84.9% in February. Across the year that is 12 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
