Envoy on RDU to MIA sits in the middle of the pack with a C+. Close to three flights in four arrive on time by the DOT's definition, 3 points worse than the national rate of 77.3%. The late ones land a little over an hour behind schedule. That rests on 102 flights, with a median arrival 5 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Envoy on RDU to MIA from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
Envoy against every carrier on RDU to MIA
Envoy flew 102 of the 2,367 flights on RDU to MIA, about 4% of it. Its 74.3% on time is 4 points worse than the route as a whole, which runs 77.8%. Ranked by on-time rate it is number three of five carriers on the route, where the range runs from Delta at 84.2% to Republic at 58.6%. Three 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 Envoy runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 13 points, against half a point between the best and worst carrier.

- 8am–11am—
- 11am–2pm32 flights65.6%
- 2pm–5pm—
- 5pm–8pm38 flights78.4%
- 8pm–5am—
Scale runs 55% to 85%. Rows with fewer than 30 flights show a dash.
The weak window here is the middle of the day, not the evening: 11am–2pm runs 65.6% on time against 78.4% for 5pm–8pm. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 5pm–8pm window is the busiest, with 38 flights scheduled in it.

| 20 July 2026 | 4 hours 44 minutes | Carrier |

Delay causes
Why Envoy runs late on this route
Carrier accounts for 56% of the 1,799 delay minutes carriers reported here, and the remaining four split what is left.
- 56%Carrier
- 26%Late-arriving aircraft
- 18%National Airspace System
- 0%Extreme weather
The largest share of delay minutes, 56%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,010 of the 1,799 delay minutes reported here. The split is drawn from 1,799 reported delay minutes.
Cancellations sit at 0.98% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
8.9% 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 a little over an hour, which a normal layover absorbs.
The 700 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 77.7% on time across 104 flights, 3 points above 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 3 points of difference.
One caution: this is a thin sample. 102 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 Envoy on RDU to MIA
Put together: treat all of this as provisional. 102 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 74.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 101 completed flights over 12 months sit behind that.
