Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1417, check with Delta Air Lines.
DL 1417 earns an A−. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 356 flights, with a median arrival 12 minutes early.
Set against the rest of the country, DL 1417's record is 10 points better than the US average of 77.6%. That gap is worth roughly 104 fewer late arrivals for every thousand flights.

These figures cover 356 flights between July 2025 and June 2026. The median arrival is 12 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 1417 flies
DL 1417 flies IAH to LGA without a single fixed slot. Its most common scheduled departure was 07:00, used on 106 of 356 flights, with 06:00 (105 flights) and 07:05 (60 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 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 1417 runs level with that at 88.0%. 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 1417 next to IAH to LGA
Every carrier on IAH to LGA combined arrived on time 72.6% of the time across 4,053 flights, so DL 1417 is 15 points ahead of it. Delta flew 1,342 flights on the same city pair under all its flight numbers, including this one, and those ran 77.2% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 6 points.

Across the year
DL 1417 quarter by quarter
DL 1417 did not run the same all year. Its best quarter was Jul–Sep 2025 at 94.5% on time and its weakest Oct–Dec 2025 at 82.6%, a swing of 12 points on roughly 89 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

- Oct–Dec 202592 flights82.6%
- Jan–Mar 202682 flights85.1%
- Apr–Jun 202691 flights89.0%
Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, DL 1417 did best on Friday at 98.0% on time and worst on Thursday at 82.4%. Each day rests on about 51 flights, so a gap of 16 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 1417 runs late
One category carries most of the weight here. Carrier accounts for 78% of the 3,278 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.
- 78%Carrier
- 17%National Airspace System
- 4%Extreme weather
The largest share of delay minutes, 78%, 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 2,565 of the 3,278 delay minutes reported here. The split is drawn from 3,278 delay minutes reported on DL 1417.
Cancellations run at 3.93%, against 1.81% nationally. That is about one flight in 25 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 2.9% 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 1,416 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 LGA to BOS (8), but none flew often enough under DL 1417 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IAH to LGA only.
One caution: this is a thin sample. 356 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 1417
For a booking, the cancellation rate is the figure to plan around on DL 1417: 3.93% of its 356 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
