B−GRADE

This route lands a B−, 6 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by close to two hours on average. That is a workable record, not a spotless one. That rests on 729 SPS to DFW flights, with a median arrival 13 minutes early.

Set against the rest of the country, this route's record is 6 points better than the US average of 77.6%. That gap is worth roughly 57 fewer late arrivals for every thousand flights.

Best ways to make this trip

The most reliable ways to fly Wichita Falls 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 2 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.

Plan this trip by month, day and time

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 729 flights.

  • 5am–8am365 flights83.7%
  • 8am–11am
  • 11am–2pm
  • 2pm–5pm364 flights82.9%
  • 5pm–8pm
  • 8pm–5am

Scale runs 75% to 90%. Rows with fewer than 30 flights show a dash.

The 5am–8am window is the strongest at 83.7% on time. The full set of windows spans about a point.

Across the year

When delays peak on this route

This route's year swings by 25 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.

On-time rate by calendar month88J86F90M85A87M78J66J82A86S81O91N81D
Darker means more delays. Figures are on-time percentages.November best, July worst

July is the worst month at 66.1% on time, 25 points below November, the best at 90.7%. 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. January was the busiest month here, with 62 flights.

Across the week, Tuesday is the strongest day at 90.2% on time and Sunday the weakest at 80.2%. 10 points is a smaller lever than departure hour, but it is free.

Delay causes

Why this route gets delayed

One category carries most of the weight here. Carrier accounts for 49% of the 13,000 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

  • Carrier
    49%
  • Late-arriving aircraft
    20%
  • Extreme weather
    19%
  • National Airspace System
    11%
  • Security
    0%

Extreme weather accounts for 19% 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 3.0 times the usual weather exposure. The split is drawn from 13,315 reported delay minutes.

The largest share of delay minutes, 49%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 6,578 of the 13,000 delay minutes reported here.

Cancellations run at 3.98%, against 1.81% nationally. That is about one flight in 25 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

8.7% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says 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 113 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 runs 83.6% on time across 729 flights, within half a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.

One caution: this is a thin sample. 729 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.

What to do with this

Booking this route

Put together: the delay figures matter less here than the 3.98% cancellation rate. A late arrival costs you close to two hours; 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. 700 completed flights over 12 months sit behind that.

Common questions

SPS to DFW questions

How often is SPS to DFW delayed?

About one flight in six arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 16.7% of the 729 flights in this analysis, against 22.4% nationally. Delayed flights are late by close to two hours on average.

How reliable is SPS to DFW compared with the rest of the country?

83.3% of flights arrive on time here against a national 77.6%, a difference of 6 points in its favour. That is worth a B− on this site's grading scale.

Does the departure time change the odds on SPS to DFW?

Not by much in this data. Every departure window falls within about a point of the others, so there is no hour worth rearranging a trip for. The overall rate of 83.3% is the figure to plan against.

How bad are July delays on SPS to DFW?

July is the weakest month at 66.1% on time, compared with 90.7% in November. Across the year that is 25 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
