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 10 points better than the national rate of 77.3%. 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.

These figures cover 364 flights between September 2025 and August 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.

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 87.5%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Delay causes

- 86%Carrier
- 7%Late-arriving aircraft
- 6%National Airspace System
- 1%Extreme weather
The largest share of delay minutes, 86%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,826 of the 4,443 delay minutes reported here. The split is drawn from 4,443 delay minutes reported on MQ 3806.
Cancellations sit at 1.10% against a national 1.89%, which is ordinary. Diversions add another 0.27%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.7% 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 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.
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: 87.5% on time and 1.10% cancelled. That is a base rate, not a promise about any single day.
