These figures cover 105 flights between September 2025 and August 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 105 of the 1,480 flights on MIA to MSY, about 7% of it. Its 86.7% on time is 12 points better than the route as a whole, which runs 74.5%. 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.

Book the morning departure. Flights leaving between 8am–11am arrive on time 92.3% of the time, against 80.0% for the afternoon window. That is 12 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 52 flights scheduled in it.

The worst days
Worst days for Envoy on MIA to MSY
The latest arrival of the period was on 8 September 2025, 2 hours 13 minutes behind schedule; most of its delay minutes were filed as extreme weather. Four of the five worst days fell in September 2025.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 8 September 2025 | 2 hours 13 minutes | Extreme weather |
| 1 July 2026 | 1 hour 35 minutes | Extreme weather |
| 12 September 2025 | 1 hour 23 minutes | Extreme weather |

Delay causes
Why Envoy runs late on this route
Extreme weather accounts for 52% of the 756 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Extreme weather
- 34%National Airspace System
- 9%Carrier
- 6%Late-arriving aircraft
Extreme weather accounts for 52% 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 8.6 times the usual weather exposure. The split is drawn from 756 reported delay minutes.
34% 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 254 minutes out of 756, against a national NAS share of 21%.
Cancellations are rare at 0.00%, below the national 1.89% 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
Badly late arrivals are rare here: only 4.8% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
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.
The return leg is a different operation and performs like one: it runs 82.7% on time across 105 flights, 4 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 4 points of difference.
One caution: this is a thin sample. 105 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. 105 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. 105 completed flights over 12 months sit behind that.
