Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Envoy Air.

Envoy on MSY to MIA lands a B+, 2 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 120 flights, with a median arrival 5 minutes early.

The US average over the same twelve months is 77.6%, so there is little to separate Envoy on MSY to MIA from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on MSY to MIA, 1,529 flights

These figures cover 120 flights between July 2025 and June 2026. The median arrival is 5 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

Envoy against every carrier on MSY to MIA

Envoy flew 120 of the 1,529 flights on MSY to MIA, about 8% of it. Its 79.8% on time is about level with the route as a whole at 79.8%. Ranked by on-time rate it is number two of five carriers on the route, where the range runs from American at 80.5% to Republic at 66.7%. 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 is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 120 flights.

5am–8am—
8am–11am—
11am–2pm75 flights77.0%
2pm–5pm—
5pm–8pm45 flights84.4%

Scale runs 70% to 90%. 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 77.0% on time against 84.4% 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 11am–2pm window is the busiest, with 75 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 79.8% on time across 120 flights.

Split by quarter, Envoy on MSY to MIA logged 80 flights in Jul–Sep 2025, 28 flights in Oct–Dec 2025, 1 flights in Jan–Mar 2026 and 11 flights in Apr–Jun 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 79.8% annual figure is the one to use.

Delay causes

Why Envoy runs late on this route

One category carries most of the weight here. Late-arriving aircraft accounts for 62% of the 1,322 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.

Late-arriving aircraft
62%
National Airspace System
30%
Carrier

Extreme weather
1%

62% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 1,322 reported delay minutes here, that single category outweighs weather by 62 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 1,322 reported delay minutes.

Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.

Connections and stage length

What a delay here costs

7.6% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.

The 674 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 is a different operation and performs like one: it runs 86.7% on time across 120 flights, 7 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 7 points of difference.

One caution: this is a thin sample. 120 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 MSY to MIA

Put together: treat all of this as provisional. 120 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 79.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 119 completed flights over 12 months sit behind that.
