These figures cover 262 flights between September 2025 and August 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.

Delay causes

Why OO 4741 runs late

Carrier accounts for 83% of the 2,526 delay minutes carriers reported here, and the remaining four split what is left.

  • Carrier
    83%
  • National Airspace System
    14%
  • Extreme weather
    3%

The largest share of delay minutes, 83%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,091 of the 2,526 delay minutes reported here. The split is drawn from 2,526 delay minutes reported on OO 4741.

Cancellations are rare at 0.76%, 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

Badly late arrivals are rare here: only 4.2% 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 1,086 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.

The same number turns up on four other city pairs in the data, including MSO to LAX (41), ORD to CRW (24) and DEN to SAT (21), but none flew often enough under OO 4741 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LEX to DEN only.

One caution: this is a thin sample. 262 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 OO 4741

For a booking, OO 4741 has one of the better records a US domestic flight can show: 89.6% on time and 0.76% cancelled. That is a base rate, not a promise about any single day.
