These figures cover 255 flights between September 2025 and August 2026. The median arrival is 14 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.

A 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and UA 2158 runs 4 points better at 93.1%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Delay causes
Why UA 2158 runs late
Carrier accounts for 53% of the 1,268 delay minutes carriers reported here, and the remaining four split what is left.
- 53%Carrier
- 29%National Airspace System
- 16%Late-arriving aircraft
- 2%Extreme weather
The largest share of delay minutes, 53%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 675 of the 1,268 delay minutes reported here. The split is drawn from 1,268 delay minutes reported on UA 2158.
Cancellations run at 3.14%, against 1.89% nationally. That is about one flight in 30 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
Badly late arrivals are rare here: only 2.4% 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 1,024 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 EWR to SAV (57), EWR to PHX (30) and EWR to CLE (21), but none flew often enough under UA 2158 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to PBI to EWR only.
One caution: this is a thin sample. 255 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 2158
For a booking, the cancellation rate is the figure to plan around on UA 2158: 3.14% of its 255 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
