This route lands a B, 5 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 about an hour on average. That is a workable record, not a spotless one. That rests on 729 DFW to BMI flights, with a median arrival 7 minutes early.
Best time to fly DFW to BMI: a 11am–2pm departure, ideally on a Tuesday. Flights in that window arrived on time 85.6% of the time and Tuesday flights 90.2%, against 82.2% for the route overall.
Set against the rest of the country, this route's record is 5 points better than the US average of 77.6%. That gap is worth roughly 46 fewer late arrivals for every thousand flights.

These figures cover 729 flights between July 2025 and June 2026. The median arrival is 7 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 BMI
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.

|---|---|---|---|---|---|
| Envoy Air | 729 | 82.2% | 66 min | 1.65% | B |

Best ways to make this trip
The most reliable ways to fly Dallas-Fort Worth to Bloomington
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. DFW → CMIDallas-Fort Worth to Champaign | Envoy Air | 82.6% | 84.1% | 1.80% | 11am–2pm, Fri | MQ 3887 18:49 |
| 2. DFW → BMIDallas-Fort Worth to Bloomington | Envoy Air | 80.8% | 82.2% | 1.65% | 11am–2pm, Tue | MQ 4254 21:01 |
| 3. DFW → PIADallas-Fort Worth to Peoria | PSA Airlines | 70.6% | 73.5% | 4.00% | 8am–11am, Tue | — |
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 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–8am—
- 8am–11am1 flights—
- 11am–2pm324 flights85.6%
- 2pm–5pm41 flights77.5%
- 5pm–8pm95 flights79.6%
- 8pm–5am268 flights79.8%
Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 85.6% on time, ahead of 2pm–5pm at 77.5%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 11am–2pm window is the busiest, with 324 flights scheduled in it.
Across the year
When delays peak on this route
This route's year swings by 24 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.
June is the worst month at 67.2% on time, 24 points below February, the best at 91.1%. 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. May was the busiest month here, with 63 flights.
Across the week, Tuesday is the strongest day at 90.2% on time and Saturday the weakest at 76.8%. 13 points is a smaller lever than departure hour, but it is free.
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 8,411 reported delay minutes.
- 38%Late-arriving aircraft
- 24%National Airspace System
- 22%Extreme weather
- 16%Carrier
Extreme weather accounts for 22% 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 3.6 times the usual weather exposure. The split is drawn from 8,411 reported delay minutes.
38% 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 8,411 reported delay minutes here, that single category outweighs weather by 2 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.
Cancellations sit at 1.65% against a national 1.81%, which is ordinary. Diversions add another 0.27%.
Connections and stage length
What a delay here actually costs
5.9% of arrivals land an hour or more late, close to the national 8.1%. 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 about an hour, which a normal layover absorbs.
The 690 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The return leg is a different operation and performs like one: it runs 88.9% on time across 729 flights, 7 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 7 points of difference.
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: treat all of this as provisional. 729 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 82.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 715 completed flights over 12 months sit behind that.
Common questions
DFW to BMI questions
How often is DFW to BMI 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 17.8% of the 729 flights in this analysis, against 22.4% nationally. Delayed flights are late by about an hour on average.
How reliable is DFW to BMI compared with the rest of the country?
82.2% of flights arrive on time here against a national 77.6%, a difference of 5 points in its favour. That is worth a B on this site's grading scale.
What time of day has the fewest delays on DFW to BMI?
The 11am–2pm departure window is the strongest at 85.6% on time. The 2pm–5pm window is the weakest at 77.5%, 8 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 June delays on DFW to BMI?
June is the weakest month at 67.2% on time, compared with 91.1% in February. Across the year that is 24 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
