These figures cover 264 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.

|---|---|---|
| 2 May 2026 | 4 hours 16 minutes | Carrier |
| 9 November 2025 | 2 hours 15 minutes | National Airspace System |
| 14 December 2025 | 2 hours 9 minutes | National Airspace System |

Delay causes
Why UA 1771 runs late
Carrier accounts for 61% of the 1,143 delay minutes carriers reported here, and the remaining four split what is left.
- 61%Carrier
- 34%National Airspace System
- 4%Extreme weather
- 1%Late-arriving aircraft
34% 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 391 minutes out of 1,143, against a national NAS share of 21%. The split is drawn from 1,143 delay minutes reported on UA 1771.
Cancellations run at 2.65%, against 1.89% nationally. That is about one flight in 40 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 2.3% 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 two other city pairs in the data, including FLL to EWR (50) and SFO to JAC (1), but none flew often enough under UA 1771 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to PBI only.
One caution: this is a thin sample. 264 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 1771
For a booking, the cancellation rate is the figure to plan around on UA 1771: 2.65% of its 264 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
