This route earns a B−. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 8 points better than the national rate of 77.3%. When something does go wrong the average delay runs an hour and a half. That rests on 1,074 GPT to DFW flights, with a median arrival 12 minutes early.
Best time to fly GPT to DFW: a 8am–11am departure, ideally on a Tuesday. Flights in that window arrived on time 90.7% of the time and Tuesday flights 90.0%, against 84.9% for the route overall.
Set against the rest of the country, this route's record is 8 points better than the US average of 77.3%. That gap is worth roughly 76 fewer late arrivals for every thousand flights.

These figures cover 1,074 flights between September 2025 and August 2026. The median arrival is 12 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.

Best ways to make this trip
The most reliable ways to fly Gulfport 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. 2 of the top 3 use a different airport at one end.
| Option | Airline | Success | On time | Cancelled | Best departure | Most punctual flight |
|---|---|---|---|---|---|---|
| 1. GPT → DFWGulfport to Dallas-Fort Worth | Envoy Air | 84.0% | 85.9% | 2.22% | 8am–11am, 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 matters more here than the choice of carrier. The gap between the best and worst window is 15 points, against half a point between the best and worst carrier.

- 8am–11am55 flights90.7%
- 11am–2pm285 flights86.4%

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 90.7% of the time, against 75.6% for the overnight window. That is 15 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 364 flights scheduled in it.

Across the year
When delays peak on this route
Twelve months, one bar each, drawn from the same 1,074 flights. The strip shows how much of this route's record is set by the calendar rather than by the operation.
September is the best month on the calendar at 89.8% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. May was the busiest month here, with 104 flights.
Across the week, Tuesday is the strongest day at 90.0% on time and Sunday the weakest at 78.4%, 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 14,000 reported delay minutes.
- 34%Carrier
- 33%Late-arriving aircraft
- 20%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 2.2 times the usual weather exposure. The split is drawn from 13,994 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 90.7% on time here.
Cancellations run at 3.07%, against 1.89% 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
5.9% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.
The 500 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 is a different operation and performs like one: it runs 81.6% on time across 1,070 flights, 3 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 3 points of difference.
One caution: this is a thin sample. 1,074 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 3.07% cancellation rate. A late arrival costs you an hour and a half; 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. 1,037 completed flights over 12 months sit behind that.
Common questions
GPT to DFW questions
How often is GPT to DFW delayed?
About one flight in seven arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 15.1% of the 1,074 flights in this analysis, against 22.7% nationally. Delayed flights are late by an hour and a half on average.
How reliable is GPT to DFW compared with the rest of the country?
84.9% of flights arrive on time here against a national 77.3%, a difference of 8 points in its favour. That is worth a B− on this site's grading scale.
What time of day has the fewest delays on GPT to DFW?
The 8am–11am departure window is the strongest at 90.7% on time. The 8pm–5am window is the weakest at 75.6%, 15 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 May delays on GPT to DFW?
May is the weakest month at 79.0% on time, compared with 89.8% in September. 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.
