United on PBI to EWR lands a B, level with the national rate of 77.3%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That rests on 2,619 flights, with a median arrival 9 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate United on PBI to EWR from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

The latest arrival of the period was on 30 October 2025, 18 hours 37 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across October, July, June and November, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 30 October 2025 | 18 hours 37 minutes | Carrier |

Delay causes
Why United runs late on this route
National Airspace System accounts for 43% of the 52,000 delay minutes carriers reported here, and the remaining four split what is left.
- 43%National Airspace System
- 28%Late-arriving aircraft
- 24%Carrier
- 4%Extreme weather
43% 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 22,000 minutes out of 52,000, against a national NAS share of 21%. The split is drawn from 51,743 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 94.4% on time here.
Cancellations sit at 2.33% against a national 1.89%, which is ordinary. Diversions add another 0.27%.
Connections and stage length
What a delay here costs
10.6% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
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 return leg runs 79.4% on time across 2,616 flights, within 2 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
The sample behind these figures is 2,619 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.
What to do with this
Booking United on PBI to EWR
Put together: the calendar is the biggest lever here, not the carrier or the hour. May runs 89.4% on time and October 70.8%, a swing of 19 points. If the dates move at all, move them out of October before you think about anything else. 2,551 completed flights over 12 months sit behind that.
