The national on-time rate over the same period is 77.3%, so this route runs 4 points behind the country as a whole. Across a thousand flights that is about 40 extra late arrivals.

Best ways to make this trip
The most reliable ways to fly Dallas-Fort Worth to Greer
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.
| Option | Airline | Success | On time | Cancelled | Best departure | Most punctual flight |
|---|---|---|---|---|---|---|
| 1. DFW → GSPDallas-Fort Worth to Greer | American Airlines | 64.2% | 66.3% | 3.17% | 11am–2pm, Tue | — |
| 2. DFW → AVLDallas-Fort Worth to Asheville | American Airlines | 62.0% | 63.9% | 3.00% | 11am–2pm, Thu | — |
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.

The 8pm–5am window is where this operation falls apart: 47.7% on time, against 85.6% for the 8am–11am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 11am–2pm window is the busiest, with 337 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 19 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.
July is the worst month at 62.7% on time, 19 points below September, the best at 81.2%. 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. July was the busiest month here, with 120 flights.
Across the week, Wednesday is the strongest day at 79.0% on time and Saturday the weakest at 66.7%, a spread of 12 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 52% of the 23,000 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Late-arriving aircraft
- 26%Carrier
- 12%National Airspace System
- 9%Extreme weather
- 0%Security
52% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 23,000 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 22,548 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 85.6% on time here.
Cancellations sit at 2.30% against a national 1.89%, which is ordinary. Diversions add another 0.51%.
Connections and stage length
What a delay here actually costs
10.8% 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.
The 862 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 76.4% on time across 1,175 flights, 3 points above 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.
The sample behind these figures is 1,173 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 calendar is the biggest lever here, not the carrier or the hour. September runs 81.2% on time and July 62.7%, a swing of 19 points. If the dates move at all, move them out of July before you think about anything else. 1,140 completed flights over 12 months sit behind that.

The 8am–11am departure window is the strongest at 85.6% on time. The 8pm–5am window is the weakest at 47.7%, 38 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 July delays on DFW to GSP?
