Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1429, check with Delta Air Lines.

DL 1429 lands a B+, 6 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 344 flights, with a median arrival 14 minutes early.

Set against the rest of the country, DL 1429's record is 6 points better than the US average of 77.6%. That gap is worth roughly 63 fewer late arrivals for every thousand flights.

These figures cover 344 flights between July 2025 and June 2026. The median arrival is 14 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.

Schedule

When DL 1429 flies

DL 1429 flies DTW to CLT without a single fixed slot. Its most common scheduled departure was 14:00, used on 104 of 344 flights, with 14:15 (62 flights) and 14:22 (40 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 14:00 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 1429 runs 12 points better at 83.9%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Against the route

DL 1429 next to DTW to CLT

Every carrier on DTW to CLT combined arrived on time 83.8% of the time across 3,537 flights, so DL 1429 is about level with it. Delta flew 1,345 flights on the same city pair under all its flight numbers, including this one, and those ran 82.3% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 2 points.

Across the year

DL 1429 quarter by quarter

Quarter by quarter DL 1429 held fairly steady: 87.0% in Jul–Sep 2025, 82.5% in Oct–Dec 2025, 81.5% in Jan–Mar 2026 and 84.3% in Apr–Jun 2026. A spread of 6 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Oct–Dec 202580 flights82.5%
Jan–Mar 202683 flights81.5%

Scale runs 75% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, DL 1429 did best on Wednesday at 90.0% on time and worst on Friday at 78.0%. Each day rests on about 49 flights, so a gap of 12 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1429 runs late

One category carries most of the weight here. Carrier accounts for 73% of the 3,466 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.

National Airspace System
11%
Extreme weather
2%

The largest share of delay minutes, 73%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 2,529 of the 3,466 delay minutes reported here. The split is drawn from 3,466 delay minutes reported on DL 1429.

Cancellations are rare at 0.58%, below the national 1.81% 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 routes

What a delay on this flight costs

6.7% 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 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. 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 same number turns up on one other city pair in the data, including MCO to LGA (16), but none flew often enough under DL 1429 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DTW to CLT only.

One caution: this is a thin sample. 344 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 DL 1429

For a booking, read DL 1429 as 83.9% on time with 0.58% cancelled over 344 flights. Those are rates from the past twelve months, not a forecast for any particular day.
