Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 4329, 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 4329 lands a B+, 2 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 268 flights, with a median arrival 5 minutes early.

These figures cover 268 flights between July 2025 and June 2026. The median arrival is 5 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 4329 flies

MQ 4329 flies PHX to LIT without a single fixed slot. Its most common scheduled departure was 16:43, used on 55 of 268 flights, with 16:06 (44 flights) and 15:39 (41 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

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 16:43 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and MQ 4329 runs 7 points better at 79.3%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Against the route

MQ 4329 next to PHX to LIT

Every carrier on PHX to LIT combined arrived on time 78.5% of the time across 276 flights, so MQ 4329 is about level with it. Across its whole network Envoy Air managed 80.2%, close to this flight's figure.

Across the year

MQ 4329 quarter by quarter

Quarter by quarter MQ 4329 held fairly steady: 77.0% in Oct–Dec 2025, 85.2% in Jan–Mar 2026 and 75.8% in Apr–Jun 2026. A spread of 9 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, MQ 4329 did best on Wednesday at 89.5% on time and worst on Sunday at 68.4%. Each day rests on about 38 flights, so a gap of 21 points is worth noticing but could still narrow in another year.

Delay causes

Why MQ 4329 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 53% of the 3,219 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.

  • Security

53% 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 3,219 reported delay minutes here, that single category outweighs weather by 53 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 3,219 delay minutes reported on MQ 4329.

Cancellations are rare at 0.75%, 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

6.0% 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 an hour, which a normal layover absorbs.

The 1,136 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 268 flights under MQ 4329 in the data flew PHX to LIT. 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. 268 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 4329

For a booking, read MQ 4329 as 79.3% on time with 0.75% cancelled over 268 flights. Those are rates from the past twelve months, not a forecast for any particular day.
