Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 3630, 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 3630 earns an A+. Nearly every flight arrives inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 16 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 30 minutes. That rests on 362 flights, with a median arrival 12 minutes early.

Set against the rest of the country, MQ 3630's record is 16 points better than the US average of 77.6%. That gap is worth roughly 160 fewer late arrivals for every thousand flights.

These figures cover 362 flights between July 2025 and June 2026. The median arrival is 12 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 3630 flies

MQ 3630 flies LIT to DCA without a single fixed slot. Its most common scheduled departure was 06:00, used on 267 of 362 flights, with 06:01 (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 3630 runs 4 points better at 93.6%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

MQ 3630 next to LIT to DCA

Every carrier on LIT to DCA combined arrived on time 93.4% of the time across 364 flights, so MQ 3630 is about level with it. Across its whole network Envoy Air managed 80.2%, which this flight beats by 13 points.

Across the year

MQ 3630 quarter by quarter

Quarter by quarter MQ 3630 held fairly steady: 89.1% in Jul–Sep 2025, 95.5% in Oct–Dec 2025, 94.3% in Jan–Mar 2026 and 95.6% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jan–Mar 202690 flights94.3%

Scale runs 80% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, MQ 3630 ranged from 90.2% on Monday to 96.2% on Wednesday. With about 52 flights behind each day, a spread of 6 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why MQ 3630 runs late

One category carries most of the weight here. National Airspace System accounts for 50% of the 684 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.

National Airspace System
50%
Carrier
43%
Extreme weather
7%

The largest share of delay minutes, 43%, 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 297 of the 684 delay minutes reported here. The split is drawn from 684 delay minutes reported on MQ 3630.

Cancellations are rare at 0.83%, 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 0.6% 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 888 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 362 flights under MQ 3630 in the data flew LIT to DCA. 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 3630

For a booking, MQ 3630 has one of the better records a US domestic flight can show: 93.6% on time and 0.83% cancelled. That is a base rate, not a promise about any single day.
