Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 4088, 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 4088 lands a B+, 6 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about 2.4 hours on average. That is a workable record, not a spotless one. That rests on 310 flights, with a median arrival 13 minutes early.

Set against the rest of the country, MQ 4088's record is 6 points better than the US average of 77.6%. That gap is worth roughly 55 fewer late arrivals for every thousand flights.

These figures cover 310 flights between July 2025 and June 2026. The median arrival is 13 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 4088 flies

MQ 4088 flies XNA to ORD without a single fixed slot. Its most common scheduled departure was 05:23, used on 41 of 310 flights, with 07:05 (37 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

  • Departs 05:2341 flights13.2%
  • Departs 07:0537 flights11.9%

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 05:23 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and MQ 4088 runs 6 points worse at 83.1%. 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 4088 next to XNA to ORD

Every carrier on XNA to ORD combined arrived on time 75.9% of the time across 1,736 flights, so MQ 4088 is 7 points ahead of it. Envoy flew 1,548 flights on the same city pair under all its flight numbers, including this one, and those ran 75.6% on time. Across its whole network Envoy Air managed 80.2%, which this flight beats by 3 points.

Across the year

MQ 4088 quarter by quarter

Quarter by quarter MQ 4088 held fairly steady: 81.8% in Jul–Sep 2025, 82.1% in Oct–Dec 2025, 85.1% in Jan–Mar 2026 and 83.1% in Apr–Jun 2026. A spread of 3 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

  • Jul–Sep 202566 flights81.8%
  • Oct–Dec 202585 flights82.1%
  • Jan–Mar 202676 flights85.1%
  • Apr–Jun 202683 flights83.1%

Scale runs 75% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, MQ 4088 did best on Saturday at 90.5% on time and worst on Monday at 76.9%. Each day rests on about 44 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Delay causes

Why MQ 4088 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 7,511 reported delay minutes.

  • Carrier
    39%
  • Late-arriving aircraft
    27%
  • National Airspace System
    21%
  • Extreme weather
    13%

Extreme weather accounts for 13% 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 2.1 times the usual weather exposure. The split is drawn from 7,511 delay minutes reported on MQ 4088.

Cancellations sit at 0.97% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

7.5% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 2.4 hours, which a normal layover absorbs.

The 522 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 310 flights under MQ 4088 in the data flew XNA 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. 310 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 4088

For a booking, read MQ 4088 as 83.1% on time with 0.97% cancelled over 310 flights. Those are rates from the past twelve months, not a forecast for any particular day.
