UA 2371 earns an A. Nearly every flight arrives inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 16 points better than the national rate of 77.6%. When something does go wrong the average delay runs close to two hours. That rests on 284 flights, with a median arrival 19 minutes early.
Set against the rest of the country, UA 2371's record is 16 points better than the US average of 77.6%. That gap is worth roughly 160 fewer late arrivals for every thousand flights.

These figures cover 284 flights between July 2025 and June 2026. The median arrival is 19 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 UA 2371 flies
UA 2371 flies LGA to IAH without a single fixed slot. Its most common scheduled departure was 07:45, used on 158 of 284 flights, with 07:30 (71 flights) and 07:55 (49 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 07:45 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and UA 2371 runs 4 points better at 93.6%. 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
UA 2371 next to LGA to IAH

Across the year
UA 2371 quarter by quarter
UA 2371 did not run the same all year. Its best quarter was Jul–Sep 2025 at 98.9% on time and its weakest Apr–Jun 2026 at 86.8%, a swing of 12 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.

- Oct–Dec 202592 flights91.2%
- Jan–Mar 202647 flights95.5%

Scale runs 80% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, UA 2371 did best on Tuesday at 100.0% on time and worst on Monday at 87.5%. Each day rests on about 41 flights, so a gap of 13 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 2371 runs late
One category carries most of the weight here. Carrier accounts for 47% of the 2,220 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.
- 47%Carrier
- 19%National Airspace System
- 17%Extreme weather
- 17%Late-arriving aircraft
Extreme weather accounts for 17% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.8 times the usual weather exposure. The split is drawn from 2,220 delay minutes reported on UA 2371.
Cancellations sit at 1.41% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 2.1% 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 four other city pairs in the data, including IAH to EWR (62), IAH to SAN (49) and MCO to DEN (37), but none flew often enough under UA 2371 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. 284 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 UA 2371
For a booking, UA 2371 has one of the better records a US domestic flight can show: 93.6% on time and 1.41% cancelled. That is a base rate, not a promise about any single day.
