Historical statistics for July 2025 to June 2026, not live status. For today’s UA 2458, check with United Airlines.
UA 2458 draws a C−. About one flight in three arrives at least 15 minutes late, and the typical late arrival is an hour and a half behind schedule. Build slack into anything you connect to. That rests on 265 flights, with a median arrival 5 minutes early.
The national on-time rate over the same period is 77.6%, so UA 2458 runs 12 points behind the country as a whole. Across a thousand flights that is about 121 extra late arrivals.

These figures cover 265 flights between July 2025 and June 2026. Beyond the headline rate, 17.6% 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 UA 2458 flies
UA 2458 flies TPA to EWR without a single fixed slot. Its most common scheduled departure was 20:05, used on 42 of 265 flights, with 19:32 (40 flights) and 19:36 (34 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 20:05 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and UA 2458 runs 5 points worse at 65.5%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.
Against the route
UA 2458 next to TPA to EWR

Across the year
UA 2458 quarter by quarter
UA 2458 did not run the same all year. Its best quarter was Apr–Jun 2026 at 90.5% on time and its weakest Jul–Sep 2025 at 41.9%, a swing of 49 points on roughly 66 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.
- Jul–Sep 202565 flights41.9%
- Oct–Dec 202584 flights66.7%
- Jan–Mar 202673 flights70.0%
- Apr–Jun 202643 flights90.5%
Scale runs 35% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, UA 2458 did best on Friday at 78.6% on time and worst on Sunday at 48.7%. Each day rests on about 38 flights, so a gap of 30 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 2458 runs late
One category carries most of the weight here. National Airspace System accounts for 46% of the 7,258 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.
- 46%National Airspace System
- 28%Late-arriving aircraft
- 18%Carrier
- 8%Extreme weather
46% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 3,374 minutes out of 7,258, against a national NAS share of 21%. The split is drawn from 7,258 delay minutes reported on UA 2458.
Cancellations run at 3.77%, against 1.81% nationally. That is about one flight in 25 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 17.6% 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 997 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 three other city pairs in the data, including IAH to ORD (41), ORD to LGA (38) and LAX to IAH (23), but none flew often enough under UA 2458 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to TPA to EWR only.
One caution: this is a thin sample. 265 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 2458
For a booking, the cancellation rate is the figure to plan around on UA 2458: 3.77% of its 265 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
