Route reliability record

DFW→CRP

Dallas-Fort Worth to Corpus Christi

Flights: 2,458
Period: July 2025 to June 2026
Distance: 355 mi
Carriers: 3

This route lands a B−, 2 points better than the national rate of 77.6%. About one flight in five arrive 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 2,458 flights, of which Envoy Air flew 1,765 at 82.0% on time.

The US average over the same twelve months is 77.6%, 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.

82.0% on time across 1,765 flights

These figures cover 2,458 flights between July 2025 and June 2026. The median arrival is 8 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Carrier by carrier

Which airline is most reliable on DFW to CRP

The choice of carrier is not cosmetic here. Envoy Air arrives on time 82.0% of the time; PSA Airlines manages 71.2%. Sample sizes sit next to every figure, because a two-point gap across 404 flights means less than a ten-point one.

On-time performance by carrier on DFW to CRP
Airline	Flights	On time	Avg delay	Cancelled	Grade
Envoy Air	1,765	82.0%	55 min	2.10%	B
SkyWest Airlinesthin sample	289	79.8%	67 min	5.54%	B−
PSA Airlines	404	71.2%	112 min	5.20%	C−

PSA Airlines cancels 5.2% 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.

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 13 points, against 11 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am53 flights82.4%
8am–11am685 flights87.3%
11am–2pm254 flights77.9%
2pm–5pm520 flights80.8%
5pm–8pm431 flights74.8%
8pm–5am515 flights74.4%

Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.

Book the morning departure. Flights leaving between 8am–11am arrive on time 87.3% of the time, against 74.4% for the overnight window. That is 13 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 685 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.

Darker means more delays. Figures are on-time percentages.November best, April worst

November is the best month on the calendar at 87.6% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. June was the busiest month here, with 256 flights.

Across the week, Thursday is the strongest day at 85.5% on time and Sunday the weakest at 75.5%. 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. Late-arriving aircraft accounts for 45% of the 33,000 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.

45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 33,000 reported delay minutes here, that single category outweighs weather by 5 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 33,071 reported delay minutes.

The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 87.3% on time here.

Cancellations run at 3.01%, against 1.81% nationally. That is roughly 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

7.1% 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 are the a little over an hour kind, which a normal layover absorbs.

At 355 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 8am–11am window matters as much as it does.

The return leg runs 80.5% on time across 2,458 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.

The sample behind these figures is 2,458 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 3.01% cancellation rate. A late arrival costs you a little over an hour; 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. 2,379 completed flights over 12 months sit behind that.

Common questions

DFW to CRP questions

How often is DFW to CRP delayed?

About one flight in five arrive at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 20.0% of the 2,458 flights in this analysis, against 22.4% nationally. Delayed flights are late by a little over an hour on average.

Which airline is most reliable on DFW to CRP?

Envoy Air leads at 82.0% on time across 1,765 flights. PSA Airlines is at the other end on 71.2%, a gap of 11 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 CRP?

The 8am–11am departure window is the strongest at 87.3% on time. The 8pm–5am window is the weakest at 74.4%, 13 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 April delays on DFW to CRP?

April is the weakest month at 73.0% on time, compared with 87.6% in November. 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.

Where to go next

Direction matters. DFW to CRP and CRP to DFW are scored separately because they are separate operations, with different departure banks and different aircraft. Compare the return leg.
