Across the year
DL 2930 quarter by quarter
DL 2930 did not run the same all year. Its best quarter was Jan–Mar 2026 at 81.9% on time and its weakest Oct–Dec 2025 at 61.4%, a swing of 21 points on roughly 70 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 2930 did best on Tuesday at 77.6% on time and worst on Sunday at 65.3%. Each day rests on about 50 flights, so a gap of 12 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late DL 2930 runs when it is late
DL 2930 often beats the schedule: 153 of 336 completed flights, 46%, arrived 15 minutes or more early. The 95 late arrivals split 31 under half an hour, 24 between 30 and 60 minutes, and 40 an hour or more.

Share of 336 completed flights by arrival against schedule.
16 of 79 late departures made up the time and arrived on time, 20% of them. In the other direction, 32 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at IAH.
The worst days
Worst days for DL 2930
The latest arrival of the period was on 20 January 2026, 9 hours behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.

|---|---|---|
| 20 January 2026 | 9 hours | Carrier |
| 9 July 2026 | 4 hours 45 minutes | Late-arriving aircraft |
| 3 August 2026 | 4 hours 26 minutes | Late-arriving aircraft |

Delay causes
Why DL 2930 runs late
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 7,145 reported delay minutes.
- 40%Carrier
- 30%National Airspace System
- 28%Late-arriving aircraft
- 2%Extreme weather
The largest share of delay minutes, 40%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,890 of the 7,145 delay minutes reported here. The split is drawn from 7,145 delay minutes reported on DL 2930.
Cancellations run at 2.87%, against 1.89% nationally. That is roughly one flight in 30 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
11.9% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
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 IAH to LGA (84), but none flew often enough under DL 2930 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LGA to IAH only.
One caution: this is a thin sample. 349 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 2930
For a booking, the cancellation rate is the figure to plan around on DL 2930: 2.87% of its 349 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.
