These figures cover 105 flights between September 2025 and August 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.

The worst days
Worst days for Envoy on MSY to MIA
The latest arrival of the period was on 8 September 2025, 1 hour 56 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. Three of the five worst days fell in September 2025.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 8 September 2025 | 1 hour 56 minutes | Late-arriving aircraft |
| 3 October 2025 | 1 hour 30 minutes | Carrier |
| 3 September 2025 | 1 hour 20 minutes | Late-arriving aircraft |
| 1 July 2026 | 1 hour 20 minutes | Late-arriving aircraft |
| 9 September 2025 | 1 hour 11 minutes | Late-arriving aircraft |
Delay causes
Why Envoy runs late on this route
Late-arriving aircraft accounts for 68% of the 895 delay minutes carriers reported here, and the remaining four split what is left.
- 68%Late-arriving aircraft
- 20%National Airspace System
- 12%Carrier
- 1%Extreme weather
68% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 895 reported delay minutes here, that single category outweighs weather by 68 to one. The split is drawn from 895 reported delay minutes.
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
5.8% 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 about 50 minutes, 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.
The return leg is a different operation and performs like one: it runs 86.7% on time across 105 flights, 4 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 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 MSY to MIA
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 82.7% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 104 completed flights over 12 months sit behind that.
