Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2930, check with Delta Air Lines.
DL 2930 sits in the middle of the pack with a C. Close to three flights in four arrive on time by the DOT's definition, 5 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 288 flights, with a median arrival 12 minutes early.
The national on-time rate over the same period is 77.6%, so DL 2930 runs 5 points behind the country as a whole. Across a thousand flights that is about 46 extra late arrivals.

These figures cover 288 flights between July 2025 and June 2026. Beyond the headline rate, 11.2% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule
When DL 2930 flies
DL 2930 flies LGA to IAH without a single fixed slot. Its most common scheduled departure was 13:45, used on 86 of 288 flights, with 13:55 (73 flights) and 13:00 (30 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 13:45 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and DL 2930 runs 6 points worse at 73.0%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

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 72 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 202586 flights61.4%
- Jan–Mar 202688 flights81.9%

Scale runs 55% to 85%. Rows with fewer than 30 flights show a dash.
By weekday, DL 2930 did best on Tuesday at 81.0% on time and worst on Sunday at 65.9%. Each day rests on about 41 flights, so a gap of 15 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 2930 runs late
One category carries most of the weight here. Carrier accounts for 43% of the 5,489 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.
- 43%Carrier
- 32%National Airspace System
- 24%Late-arriving aircraft
- 2%Extreme weather
The largest share of delay minutes, 43%, 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 2,333 of the 5,489 delay minutes reported here. The split is drawn from 5,489 delay minutes reported on DL 2930.
Cancellations sit at 2.43% against a national 1.81%, which is ordinary. Diversions add another 1.04%.
Connections and routes
What a delay on this flight costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 11.2% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum 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. 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 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. 288 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
