Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 4044, 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 4044 earns an A+. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 12 points better than the national rate of 77.6%. When something does go wrong the average delay runs close to two hours. That rests on 252 flights, with a median arrival 6 minutes early.

Set against the rest of the country, MQ 4044's record is 12 points better than the US average of 77.6%. That gap is worth roughly 117 fewer late arrivals for every thousand flights.

These figures cover 252 flights between July 2025 and June 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.

Schedule

When MQ 4044 flies

MQ 4044 flies EYW to MIA without a single fixed slot. Its most common scheduled departure was 12:00, used on 60 of 252 flights, with 06:45 (43 flights) and 11:25 (33 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

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

A 12:00 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and MQ 4044 runs 11 points better at 89.3%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

MQ 4044 quarter by quarter

MQ 4044 did not run the same all year. Its best quarter was Apr–Jun 2026 at 95.3% on time and its weakest Jul–Sep 2025 at 83.0%, a swing of 12 points on roughly 63 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 202588 flights83.0%
Oct–Dec 202585 flights90.6%
Jan–Mar 202636 flights94.4%

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, MQ 4044 did best on Thursday at 100.0% on time and worst on Tuesday at 84.2%. Each day rests on about 36 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why MQ 4044 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 52% of the 2,719 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Late-arriving aircraft
52%
Carrier
39%
National Airspace System
9%

52% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 2,719 reported delay minutes here, that single category outweighs weather by 52 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 2,719 delay minutes reported on MQ 4044.

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 routes

What a delay on this flight costs

Badly late arrivals are rare here: only 4.8% 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 same number turns up on three other city pairs in the data, including MIA to EYW (116), ORD to SYR (41) and SYR to ORD (41), but none flew often enough under MQ 4044 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EYW to MIA only.

One caution: this is a thin sample. 252 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 4044

For a booking, MQ 4044 has one of the better records a US domestic flight can show: 89.3% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
