MQ 4086 lands a B+, 4 points better than the national rate of 77.3%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by about 50 minutes on average. That rests on 357 flights, with a median arrival 4 minutes early.

These figures cover 357 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 4086 quarter by quarter
MQ 4086 did not run the same all year. Its best quarter was Oct–Dec 2025 at 86.8% on time and its weakest Jul–Sep 2026 at 72.6%, a swing of 14 points on roughly 71 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.

Scale runs 65% to 90%.
By weekday, MQ 4086 did best on Saturday at 87.2% on time and worst on Sunday at 67.3%. Each day rests on about 51 flights, so a gap of 20 points is worth noticing but could still narrow in another year.

The worst days
Worst days for MQ 4086
The latest arrival of the period was on 18 January 2026, 2 hours 19 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 18 January 2026 | 2 hours 19 minutes | Late-arriving aircraft |
| 29 August 2026 | 2 hours 5 minutes | Carrier |
| 12 October 2025 | 2 hours 4 minutes | Late-arriving aircraft |
| 28 December 2025 | 1 hour 58 minutes | Carrier |
| 26 September 2025 | 1 hour 45 minutes | Late-arriving aircraft |
Delay causes
Why MQ 4086 runs late
Late-arriving aircraft accounts for 50% of the 3,240 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Late-arriving aircraft
- 35%Carrier
- 15%National Airspace System
50% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,240 reported delay minutes here, that single category outweighs weather by 50 to one. The split is drawn from 3,240 delay minutes reported on MQ 4086.
Cancellations are rare at 0.56%, 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
5.6% 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 50 minutes, which a normal layover absorbs.
The 1,023 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 357 flights under MQ 4086 in the data flew PHX to XNA. 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. 357 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 4086
For a booking, read MQ 4086 as 81.6% on time with 0.56% cancelled over 357 flights. Those are rates from the past twelve months, not a forecast for any particular day.
