Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 3806, 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 3806 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 11 points better than the national rate of 77.6%. When something does go wrong the average delay runs an hour and a half. That rests on 364 flights, with a median arrival 8 minutes early.
Set against the rest of the country, MQ 3806's record is 11 points better than the US average of 77.6%. That gap is worth roughly 105 fewer late arrivals for every thousand flights.

These figures cover 364 flights between July 2025 and June 2026. The median arrival is 8 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 3806 flies
MQ 3806 flies GSP to MIA without a single fixed slot. Its most common scheduled departure was 06:00, used on 146 of 364 flights, with 05:00 (48 flights) and 07:00 (41 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 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and MQ 3806 runs level with that at 88.1%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
MQ 3806 quarter by quarter
MQ 3806 did not run the same all year. Its best quarter was Jul–Sep 2025 at 94.6% on time and its weakest Jan–Mar 2026 at 77.6%, a swing of 17 points on roughly 91 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 202592 flights94.6%
- Oct–Dec 202592 flights91.3%
- Jan–Mar 202689 flights77.6%
- Apr–Jun 202691 flights87.9%
Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, MQ 3806 ranged from 82.7% on Thursday to 94.0% on Sunday. With about 52 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why MQ 3806 runs late
One category carries most of the weight here. Carrier accounts for 85% of the 4,078 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.
- 85%Carrier
- 8%Late-arriving aircraft
- 7%National Airspace System
- 1%Extreme weather
The largest share of delay minutes, 85%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 3,446 of the 4,078 delay minutes reported here. The split is drawn from 4,078 delay minutes reported on MQ 3806.
Cancellations sit at 1.10% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 3.6% 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 637 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 364 flights under MQ 3806 in the data flew GSP to MIA. 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. 364 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 3806
For a booking, MQ 3806 has one of the better records a US domestic flight can show: 88.1% on time and 1.10% cancelled. That is a base rate, not a promise about any single day.
