These figures cover 362 flights between September 2025 and August 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 is scheduled to leave Little Rock (LIT) at 06:00 local time and reach Washington (DCA) at 09:29. That slot held for 300 of the 362 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

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.

Across the year
MQ 3630 quarter by quarter
MQ 3630 did not run the same all year. Its best quarter was Apr–Jun 2026 at 95.6% on time and its weakest Jul–Sep 2025 at 83.3%, a swing of 12 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.

Delay causes
Why MQ 3630 runs late
National Airspace System accounts for 49% of the 825 delay minutes carriers reported here, and the remaining four split what is left.
- 49%National Airspace System
- 27%Extreme weather
- 24%Carrier
Extreme weather accounts for 27% 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 4.5 times the usual weather exposure. The split is drawn from 825 delay minutes reported on MQ 3630.
Cancellations are rare at 0.83%, 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 0.8% 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 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.
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.
