Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1455, check with Delta Air Lines.

DL 1455 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 287 flights, with a median arrival 2 minutes early.

Set against the rest of the country, DL 1455's record is 6 points better than the US average of 77.6%. That gap is worth roughly 59 fewer late arrivals for every thousand flights.

These figures cover 287 flights between July 2025 and June 2026. The median arrival is 2 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 1455 flies

DL 1455 flies DTW to MCO without a single fixed slot. Its most common scheduled departure was 08:45, used on 90 of 287 flights, with 06:00 (38 flights) and 08:38 (34 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 08:45 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and DL 1455 runs level with that at 83.5%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

DL 1455 next to DTW to MCO

Every carrier on DTW to MCO combined arrived on time 75.6% of the time across 3,680 flights, so DL 1455 is 8 points ahead of it. Delta flew 2,170 flights on the same city pair under all its flight numbers, including this one, and those ran 74.6% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 2 points.

Across the year

DL 1455 quarter by quarter

Quarter by quarter DL 1455 held fairly steady: 83.3% in Jul–Sep 2025, 82.0% in Oct–Dec 2025, 84.8% in Jan–Mar 2026 and 83.5% in Apr–Jun 2026. A spread of 3 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights83.3%
Oct–Dec 202550 flights82.0%
Jan–Mar 202666 flights84.8%

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

By weekday, DL 1455 ranged from 77.5% on Saturday to 88.1% on Tuesday. With about 41 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 1455 runs late

One category carries most of the weight here. Carrier accounts for 79% of the 3,191 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.

Carrier
79%
National Airspace System
16%
Late-arriving aircraft
4%
Extreme weather
1%

The largest share of delay minutes, 79%, 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 2,525 of the 3,191 delay minutes reported here. The split is drawn from 3,191 delay minutes reported on DL 1455.

Cancellations are rare at 0.35%, 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

Badly late arrivals are rare here: only 3.5% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

The 957 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 three other city pairs in the data, including MCO to DTW (242), MSP to ORD (1) and ORD to MSP (1), but none flew often enough under DL 1455 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DTW to MCO only.

One caution: this is a thin sample. 287 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 1455

For a booking, read DL 1455 as 83.5% on time with 0.35% cancelled over 287 flights. Those are rates from the past twelve months, not a forecast for any particular day.
