Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with United Airlines.
United on PBI to EWR lands a B, about a point worse than the national rate of 77.6%. About one flight in four arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 2,773 flights, with a median arrival 8 minutes early.
The US average over the same twelve months is 77.6%, 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.

These figures cover 2,773 flights between July 2025 and June 2026. Beyond the headline rate, 11.8% 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.
Carrier by carrier
United against every carrier on PBI to EWR
United flew 2,773 of the 3,612 flights on PBI to EWR, most of the route. Its 76.3% on time is 2 points better than the route as a whole, which runs 74.5%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from United at 76.3% to Spirit at 51.4%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window
When United runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 35 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am486 flights94.3%
- 8am–11am529 flights89.6%
- 11am–2pm485 flights79.9%
- 2pm–5pm562 flights63.1%
- 5pm–8pm587 flights59.4%
- 8pm–5am124 flights72.5%
Scale runs 50% to 100%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 59.4% on time, against 94.3% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 5pm–8pm window is the busiest, with 587 flights scheduled in it.
Across the year
United on PBI to EWR through the year
July is the worst month at 54.6% on time, 35 points below May, the best at 89.4%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. March was the busiest month here, with 307 flights.
Across the week, Tuesday is the strongest day at 81.2% on time and Sunday the weakest at 68.0%. 13 points is a smaller lever than departure hour, but it is free.
Delay causes
Why United runs late on this route
One category carries most of the weight here. National Airspace System accounts for 48% of the 62,000 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.
- 48%National Airspace System
- 26%Late-arriving aircraft
- 25%Carrier
- 1%Extreme weather
48% 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 30,000 minutes out of 62,000, against a national NAS share of 21%. The split is drawn from 62,004 reported delay minutes.
Cancellations sit at 2.24% against a national 1.81%, which is ordinary. Diversions add another 0.22%.
Connections and stage length
What a delay here costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 11.8% 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 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. 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 return leg runs 79.1% on time across 2,770 flights, within 3 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 2,773 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 July 54.6%, a swing of 35 points. If the dates move at all, move them out of July before you think about anything else. 2,705 completed flights over 12 months sit behind that.
