These figures cover 263 flights between September 2025 and August 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.

The worst days
Worst days for UA 2371
The latest arrival of the period was on 23 March 2026, 8 hours 7 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across March, December, October and July, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 23 March 2026 | 8 hours 7 minutes | Carrier |
| 8 December 2025 | 6 hours 37 minutes | Carrier |
| 14 December 2025 | 6 hours 33 minutes | Extreme weather |
| 18 October 2025 | 6 hours 19 minutes | Late-arriving aircraft |
| 19 July 2026 | 3 hours 30 minutes | Late-arriving aircraft |
Delay causes
Why UA 2371 runs late
Carrier accounts for 44% of the 2,632 delay minutes carriers reported here, and the remaining four split what is left.
- 44%Carrier
- 22%Late-arriving aircraft
- 19%National Airspace System
- 15%Extreme weather
Extreme weather accounts for 15% 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 2.5 times the usual weather exposure. The split is drawn from 2,632 delay minutes reported on UA 2371.
Cancellations sit at 1.90% against a national 1.89%, 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 3.5% 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 four other city pairs in the data, including IAH to EWR (124), 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. 263 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, read UA 2371 as 91.5% on time with 1.90% cancelled over 263 flights. Those are rates from the past twelve months, not a forecast for any particular day.
