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

Envoy on MIA to MSY earns an A+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 9 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 120 flights, with a median arrival 7 minutes early.

Set against the rest of the country, Envoy's MIA to MSY record is 9 points better than the US average of 77.6%. That gap is worth roughly 91 fewer late arrivals for every thousand flights.

Every carrier on MIA to MSY, 1,532 flights

These figures cover 120 flights between July 2025 and June 2026. The median arrival is 7 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 MIA to MSY

Envoy flew 120 of the 1,532 flights on MIA to MSY, about 8% of it. Its 86.7% on time is 14 points better than the route as a whole, which runs 72.8%. Ranked by on-time rate it is first of five carriers on the route, where the range runs from Envoy at 86.7% to Frontier at 50.0%. 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.

8am–11am75 flights89.3%

Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.

The early departures do better, though not dramatically: 89.3% on time for the 8am–11am window against 81.8% for 2pm–5pm. Worth taking if the schedule allows, not worth an extra connection. The 8am–11am 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 86.7% on time across 120 flights.

Split by quarter, Envoy on MIA to MSY 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 86.7% annual figure is the one to use.

Delay causes

Why Envoy runs late on this route

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 930 reported delay minutes.

Extreme weather
31%
National Airspace System
28%
Carrier
21%
Late-arriving aircraft
20%

Extreme weather accounts for 31% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 5.0 times the usual weather exposure. The split is drawn from 930 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

5.0% 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 79.8% on time across 120 flights, 7 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 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 MIA to MSY

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 86.7% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 120 completed flights over 12 months sit behind that.
