These figures cover 286 flights between September 2025 and August 2026. The median arrival is 9 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 07:30 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and UA 2326 runs level with that at 90.5%. 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
UA 2326 quarter by quarter
UA 2326 did not run the same all year. Its best quarter was Jul–Sep 2025 at 96.7% on time and its weakest Jan–Mar 2026 at 81.5%, a swing of 15 points on roughly 57 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.

The worst days
Worst days for UA 2326
The latest arrival of the period was on 4 December 2025, 2 hours 35 minutes 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.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 4 December 2025 | 2 hours 35 minutes | Carrier |
| 7 February 2026 | 2 hours 14 minutes | Carrier |
| 13 September 2025 | 2 hours 3 minutes | Extreme weather |

Delay causes
Why UA 2326 runs late
National Airspace System accounts for 44% of the 1,238 delay minutes carriers reported here, and the remaining four split what is left.
- 44%National Airspace System
- 38%Carrier
- 11%Extreme weather
- 7%Late-arriving aircraft
Extreme weather accounts for 11% 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 1.9 times the usual weather exposure. The split is drawn from 1,238 delay minutes reported on UA 2326.
Cancellations are rare at 0.70%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
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 8.3% 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 1,012 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 two other city pairs in the data, including TPA to IAH (125) and TPA to LAX (24), but none flew often enough under UA 2326 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to TPA only.
One caution: this is a thin sample. 286 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 2326
For a booking, UA 2326 has one of the better records a US domestic flight can show: 90.5% on time and 0.70% cancelled. That is a base rate, not a promise about any single day.
