MQ 4230 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 77.3%. When something does go wrong the average delay runs about an hour. That rests on 330 flights, with a median arrival 11 minutes early.
Set against the rest of the country, MQ 4230's record is 10 points better than the US average of 77.3%. That gap is worth roughly 100 fewer late arrivals for every thousand flights.

These figures cover 330 flights between September 2025 and August 2026. The median arrival is 11 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.

Delay causes
Why MQ 4230 runs late
Late-arriving aircraft accounts for 45% of the 2,606 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Late-arriving aircraft
- 27%Carrier
- 25%National Airspace System
- 2%Extreme weather
45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,606 reported delay minutes here, that single category outweighs weather by 18 to one. The split is drawn from 2,606 delay minutes reported on MQ 4230.
Cancellations sit at 2.12% against a national 1.89%, which is ordinary. Diversions add another 0.30%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.7% land an hour or more behind schedule, against 8.3% 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 868 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.
MQ 4230 is not only a DFW to TRI flight. It also flew TRI to DFW (312 flights, 81.8% 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. 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.
