Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 3808, 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 3808 sits in the middle of the pack with a C−. About seven flights in ten arrive on time by the DOT's definition, 9 points worse than the national rate of 77.6%. The late ones land an hour and a half behind schedule. That rests on 353 flights, with a median arrival 4 minutes early.
The national on-time rate over the same period is 77.6%, so MQ 3808 runs 9 points behind the country as a whole. Across a thousand flights that is about 89 extra late arrivals.

These figures cover 353 flights between July 2025 and June 2026. Beyond the headline rate, 12.5% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule
When MQ 3808 flies
MQ 3808 is scheduled to leave White Plains (HPN) at 16:30 local time and reach Chicago (ORD) at 18:18. That slot held for 353 of the 353 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 16:30 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and MQ 3808 runs 4 points worse at 68.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

MQ 3808 next to HPN to ORD

Across the year
MQ 3808 quarter by quarter
MQ 3808 did not run the same all year. Its best quarter was Jan–Mar 2026 at 76.5% on time and its weakest Jul–Sep 2025 at 61.6%, a swing of 15 points on roughly 88 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 202591 flights61.6%
- Oct–Dec 202588 flights62.4%
- Jan–Mar 202689 flights76.5%
- Apr–Jun 202685 flights74.7%
Scale runs 55% to 80%. Rows with fewer than 30 flights show a dash.
By weekday, MQ 3808 did best on Saturday at 87.5% on time and worst on Friday at 55.1%. Each day rests on about 50 flights, so a gap of 32 points is worth noticing but could still narrow in another year.
Delay causes
Why MQ 3808 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 43% of the 9,453 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.
- 43%Late-arriving aircraft
- 38%National Airspace System
- 12%Extreme weather
- 7%Carrier
Extreme weather accounts for 12% 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 1.9 times the usual weather exposure. The split is drawn from 9,453 delay minutes reported on MQ 3808.
Cancellations run at 4.82%, against 1.81% nationally. That is about one flight in twenty cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 12.5% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
The 738 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 353 flights under MQ 3808 in the data flew HPN to ORD. 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. 353 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 3808
For a booking, the cancellation rate is the figure to plan around on MQ 3808: 4.82% of its 353 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
