These figures cover 357 flights between September 2025 and August 2026. The median arrival is 10 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.

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 87.4%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

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 100.0% on time and its weakest Oct–Dec 2025 at 82.6%, a swing of 17 points on roughly 71 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.

By weekday, DL 1417 did best on Friday at 98.0% on time and worst on Monday at 80.0%. Each day rests on about 51 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

Worst days for DL 1417
The latest arrival of the period was on 7 February 2026, 14 hours 23 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 7 February 2026 | 14 hours 23 minutes | Carrier |
| 21 March 2026 | 2 hours 55 minutes | Carrier |
| 26 February 2026 | 2 hours 11 minutes | Carrier |

Delay causes
Why DL 1417 runs late
Carrier accounts for 70% of the 2,804 delay minutes carriers reported here, and the remaining four split what is left.
- 70%Carrier
- 25%National Airspace System
- 5%Extreme weather
The largest share of delay minutes, 70%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,955 of the 2,804 delay minutes reported here. The split is drawn from 2,804 delay minutes reported on DL 1417.
Cancellations run at 4.48%, against 1.89% nationally. That is roughly one flight in twenty 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 8.3% 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.
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. 357 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: 4.48% of its 357 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
