Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 3929, 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 3929 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 77.6%. When something does go wrong the average delay runs about 55 minutes. That rests on 274 flights, with a median arrival 9 minutes early.
Set against the rest of the country, MQ 3929's record is 10 points better than the US average of 77.6%. That gap is worth roughly 99 fewer late arrivals for every thousand flights.

These figures cover 274 flights between July 2025 and June 2026. The median arrival is 9 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 3929 flies
MQ 3929 flies PHX to RDM without a single fixed slot. Its most common scheduled departure was 10:22, used on 53 of 274 flights, with 11:50 (37 flights) and 10:30 (36 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

- Departs 10:3036 flights13.1%

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 10:22 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and MQ 3929 runs 3 points better 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.
Against the route
MQ 3929 next to PHX to RDM
Every carrier on PHX to RDM combined arrived on time 86.9% of the time across 841 flights, so MQ 3929 is about level with it. Envoy flew 805 flights on the same city pair under all its flight numbers, including this one, and those ran 87.3% on time. Across its whole network Envoy Air managed 80.2%, which this flight beats by 7 points.

Across the year
MQ 3929 quarter by quarter
Quarter by quarter MQ 3929 held fairly steady: 89.0% in Jul–Sep 2025, 89.0% in Oct–Dec 2025 and 83.5% in Jan–Mar 2026. A spread of 6 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, MQ 3929 did best on Saturday at 94.3% on time and worst on Friday at 75.0%. Each day rests on about 39 flights, so a gap of 19 points is worth noticing but could still narrow in another year.
Delay causes
Why MQ 3929 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 62% of the 1,835 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.
- 62%Late-arriving aircraft
- 25%Carrier
- 13%National Airspace System
- 0%Extreme weather
62% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 1,835 reported delay minutes here, that single category outweighs weather by 62 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 1,835 delay minutes reported on MQ 3929.
Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are 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 4.0% 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 893 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.
MQ 3929 is not only a PHX to RDM flight. It also flew RDM to PHX (266 flights, 89.0% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
One caution: this is a thin sample. 274 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 3929
For a booking, MQ 3929 has one of the better records a US domestic flight can show: 87.5% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
