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 2,751 TUL to DFW flights, of which Envoy Air flew 840 at 85.2% on time.
Best time to fly TUL to DFW: a 5am–8am departure, ideally on a Tuesday. Flights in that window arrived on time 87.8% of the time and Tuesday flights 84.8%, against 79.1% 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 TUL to DFW
The choice of carrier is not cosmetic here. Envoy Air arrives on time 85.2% of the time; American Airlines manages 76.7%. Sample sizes sit next to every figure, because a two-point gap across 1,606 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Envoy Air | 840 | 85.2% | 66 min | 2.62% | A |
| SkyWest Airlinesthin sample | 151 | 80.1% | 79 min | 3.31% | B− |

| PSA Airlinesthin sample | 154 | 68.7% | 88 min | 4.55% | C− |
American Airlines cancels 3.2% 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 Tulsa 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. 1 of the top 3 use a different airport at one end.
| Option | Airline | Success | On time | Cancelled | Best departure | Most punctual flight |
|---|---|---|---|---|---|---|
| 1. TUL → DALTulsa to Dallas | Southwest Airlines | 86.0% | 87.2% | 1.34% | 5am–8am, Wed | — |
| 2. TUL → DFWTulsa to Dallas-Fort Worth | Envoy Air | 83.0% | 85.2% | 2.62% | 5am–8am, Fri | — |
| 3. TUL → DFWTulsa to Dallas-Fort Worth | American Airlines | 74.3% | 76.7% | 3.18% | 5am–8am, Tue | AA 1090 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 9 points between the best and worst carrier.
- 5am–8am977 flights87.8%
- 8am–11am377 flights84.2%
- 11am–2pm475 flights79.7%
- 2pm–5pm332 flights64.6%
- 5pm–8pm379 flights67.8%
- 8pm–5am211 flights71.4%
Scale runs 55% to 95%.
Book the early departure. Flights leaving between 5am–8am arrive on time 87.8% of the time, against 64.6% for the afternoon 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 977 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 15 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.
June is the worst month at 69.9% on time, 15 points below January, the best at 84.9%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. October was the busiest month here, with 255 flights.
Across the week, Tuesday is the strongest day at 84.8% on time and Sunday the weakest at 72.8%, a spread of 12 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 54,000 reported delay minutes.
- 41%Late-arriving aircraft
- 32%Carrier
- 14%National Airspace System
- 13%Extreme weather
- 0%Security
Extreme weather accounts for 13% 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 2.1 times the usual weather exposure. The split is drawn from 54,141 reported delay minutes.
41% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 54,000 reported delay minutes here, that single category outweighs weather by 3 to one.
Cancellations run at 3.09%, 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
9.2% 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.
At 237 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 73.2% on time across 2,747 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 2,751 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 3.09% 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. 2,658 completed flights over 12 months sit behind that.
Common questions
TUL to DFW questions
How often is TUL 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 20.9% of the 2,751 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 TUL to DFW?
Envoy Air leads at 85.2% on time across 840 flights. American Airlines is at the other end on 76.7%, a gap of 9 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 TUL to DFW?
The 5am–8am departure window is the strongest at 87.8% on time. The 2pm–5pm window is the weakest at 64.6%, 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 June delays on TUL to DFW?
June is the weakest month at 69.9% on time, compared with 84.9% in January. Across the year that is 15 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
