MQ 4109 lands a B+, 6 points better than the national rate of 77.3%. About one flight in six arrives 15 minutes late or worse, and those flights are late by roughly 55 minutes on average. That rests on 362 flights, with a median arrival 6 minutes early.
Set against the rest of the country, MQ 4109's record is 6 points better than the US average of 77.3%. That gap is worth roughly 64 fewer late arrivals for every thousand flights.

These figures cover 362 flights between September 2025 and August 2026. The median arrival is 6 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.

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 Apr–Jun 2026 at 79.1%, a swing of 10 points on roughly 72 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.

Scale runs 70% to 95%.
By weekday, MQ 4109 did best on Tuesday at 92.2% on time and worst on Sunday at 75.5%. Each day rests on about 52 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

The worst days
Worst days for MQ 4109
The latest arrival of the period was on 6 March 2026, 8 hours 53 minutes behind schedule; most of its delay minutes were filed as extreme weather. The five worst days are spread across March, September, July and January, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 March 2026 | 8 hours 53 minutes | Extreme weather |
| 16 March 2026 | 8 hours 17 minutes | Extreme weather |
| 16 September 2025 | 1 hour 47 minutes | Carrier |
| 10 July 2026 | 1 hour 43 minutes | National Airspace System |
| 4 January 2026 | 1 hour 26 minutes | Late-arriving aircraft |
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 3,085 reported delay minutes.
- 40%Late-arriving aircraft
- 31%Extreme weather
- 16%National Airspace System
- 13%Carrier
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 quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 5.2 times the usual weather exposure. The split is drawn from 3,085 delay minutes reported on MQ 4109.
Cancellations are rare at 0.55%, below the national 1.89% 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 8.3% 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 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.
Every one of the 362 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. 362 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 83.7% on time with 0.55% cancelled over 362 flights. Those are rates from the past twelve months, not a forecast for any particular day.
