Every carrier on CLT to EWR, 3,690 flights
These figures cover 724 flights between September 2025 and August 2026. The median arrival is 11 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.

Carrier by carrier
United against every carrier on CLT to EWR
United flew 724 of the 3,690 flights on CLT to EWR, about 20% of it. Its 82.0% on time is 6 points better than the route as a whole, which runs 75.9%. Ranked by on-time rate it is first of four carriers on the route, where the range runs from United at 82.0% to American at 71.5%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. Republic Airways arrives on time 81.0% of the time; American Airlines manages 71.5%. Sample sizes sit next to every figure, because a two-point gap across 1,831 flights means less than a ten-point one.

Republic Airways cancels 7.3% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

Delay causes
Why United runs late on this route
National Airspace System accounts for 55% of the 11,000 delay minutes carriers reported here, and the remaining four split what is left.
- 55%National Airspace System
- 33%Late-arriving aircraft
- 12%Carrier
55% 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 6,221 minutes out of 11,000, against a national NAS share of 21%. The split is drawn from 11,320 reported delay minutes.
Cancellations sit at 2.49% against a national 1.89%, which is ordinary. Diversions add another 0.28%.
Connections and stage length
What a delay here costs
7.5% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.
The 529 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 is a different operation and performs like one: it runs 75.7% on time across 723 flights, 6 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 6 points of difference.
One caution: this is a thin sample. 724 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 United on CLT to EWR
Put together: treat all of this as provisional. 724 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 82.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 704 completed flights over 12 months sit behind that.
