Flights: 361
Period: July 2025 to June 2026

Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 4109, check with Envoy Air. Envoy Air flies under contract for larger airlines, so a ticket for this flight may show a different airline code and number.

MQ 4109 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 roughly 50 minutes on average. That is a workable record, not a spotless one. That rests on 361 flights, with a median arrival 5 minutes early.

These figures cover 361 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.

Schedule

When MQ 4109 flies

MQ 4109 flies MIA to PNS without a single fixed slot. Its most common scheduled departure was 22:56, used on 59 of 361 flights, with 23:10 (41 flights) and 22:50 (37 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 22:56 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and MQ 4109 runs 10 points better at 80.0%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

MQ 4109 next to MIA to PNS

Every carrier on MIA to PNS combined arrived on time 82.8% of the time across 1,231 flights, so MQ 4109 is 3 points behind it. Envoy flew 1,225 flights on the same city pair under all its flight numbers, including this one, and those ran 83.2% on time. Across its whole network Envoy Air managed 80.2%, close to this flight's figure.

Across the year

MQ 4109 quarter by quarter

MQ 4109 did not run the same all year. Its best quarter was Oct–Dec 2025 at 89.5% on time and its weakest Jul–Sep 2025 at 72.5%, a swing of 17 points on roughly 90 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Jul–Sep 202591 flights72.5%
Oct–Dec 202589 flights89.5%
Jan–Mar 202690 flights79.3%
Apr–Jun 202691 flights79.1%

Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, MQ 4109 did best on Tuesday at 86.5% on time and worst on Sunday at 67.3%. Each day rests on about 52 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Delay causes

Why MQ 4109 runs late

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 3,407 reported delay minutes.

Late-arriving aircraft
41%
Extreme weather
28%
Carrier
20%
National Airspace System
11%

Extreme weather accounts for 28% 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 quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 4.5 times the usual weather exposure. The split is drawn from 3,407 delay minutes reported on MQ 4109.

Cancellations are rare at 0.55%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 3.1% land an hour or more behind schedule, against 8.1% 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 530 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.

Every one of the 361 flights under MQ 4109 in the data flew MIA to PNS. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 361 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 MQ 4109

For a booking, read MQ 4109 as 80.0% on time with 0.55% cancelled over 361 flights. Those are rates from the past twelve months, not a forecast for any particular day.
