Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Frontier Airlines.
Frontier on DFW to IND lands a B+, 3 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 a little over an hour on average. That rests on 120 flights, with a median arrival 13 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Frontier on DFW to IND from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
Frontier against every carrier on DFW to IND
Frontier flew 120 of the 2,044 flights on DFW to IND, about 6% of it. Its 80.7% on time is 10 points better than the route as a whole, which runs 70.3%. Ranked by on-time rate it is number four of five carriers on the route, where the range runs from Spirit at 100.0% to American at 69.3%. Three of those carriers flew fewer than 365 flights here, so treat their positions as rough.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Book the morning departure. Flights leaving between 8am–11am arrive on time 80.0% of the time, against 65.6% for the evening window. That is 14 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5pm–8pm window is the busiest, with 33 flights scheduled in it.

The latest arrival of the period was on 19 June 2026, 5 hours 51 minutes behind schedule; most of its delay minutes were filed as extreme weather. Three of the five worst days fell in August 2026.
| Date | Arrived late by | Largest filed cause |

| 19 June 2026 | 5 hours 51 minutes | Extreme weather |
| 7 August 2026 | 3 hours 25 minutes | Late-arriving aircraft |

Delay causes
Why Frontier runs late on this route
Late-arriving aircraft accounts for 53% of the 1,823 delay minutes carriers reported here, and the remaining four split what is left.
- 53%Late-arriving aircraft
- 21%National Airspace System
- 19%Extreme weather
- 7%Carrier
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 3.1 times the usual weather exposure. The split is drawn from 1,823 reported delay minutes.
53% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 1,823 reported delay minutes here, that single category outweighs weather by 3 to one.
Cancellations are rare at 0.83%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and stage length
What a delay here 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.
The 761 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 71.4% on time across 120 flights, 9 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 9 points of difference.
One caution: this is a thin sample. 120 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 Frontier on DFW to IND
Put together: treat all of this as provisional. 120 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 80.7% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 119 completed flights over 12 months sit behind that.
