MQ 4329 lands a B+, about a point better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That rests on 330 flights, with a median arrival 4 minutes early.

These figures cover 330 flights between September 2025 and August 2026. The median arrival is 4 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.

Across the year
MQ 4329 quarter by quarter
MQ 4329 did not run the same all year. Its best quarter was Jan–Mar 2026 at 85.2% on time and its weakest Jul–Sep 2026 at 74.2%, a swing of 11 points on roughly 83 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.

- Apr–Jun 202691 flights75.8%

Scale runs 65% to 90%.
By weekday, MQ 4329 did best on Tuesday at 85.1% on time and worst on Sunday at 70.2%. Each day rests on about 47 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Share of 328 completed flights by arrival against schedule.
14 of 68 late departures made up the time and arrived on time, 21% of them. In the other direction, 17 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at LIT.
The worst days
Worst days for MQ 4329
The latest arrival of the period was on 4 July 2026, 6 hours 7 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 4 July 2026 | 6 hours 7 minutes | Late-arriving aircraft |
| 22 May 2026 | 4 hours 14 minutes | Late-arriving aircraft |
| 4 April 2026 | 3 hours 27 minutes | Late-arriving aircraft |
| 26 October 2025 | 3 hours 1 minute | Late-arriving aircraft |
| 31 January 2026 | 2 hours 52 minutes | Late-arriving aircraft |
Delay causes
Why MQ 4329 runs late
Late-arriving aircraft accounts for 57% of the 4,252 delay minutes carriers reported here, and the remaining four split what is left.
- 57%Late-arriving aircraft
- 23%Carrier
- 20%National Airspace System
- 0%Security
57% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,252 reported delay minutes here, that single category outweighs weather by 57 to one. The split is drawn from 4,252 delay minutes reported on MQ 4329.
Cancellations are rare at 0.61%, 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
5.8% of arrivals land an hour or more late, close to the national 8.3%, so 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.
Every one of the 330 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. 330 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 78.4% on time with 0.61% cancelled over 330 flights. Those are rates from the past twelve months, not a forecast for any particular day.
