The weak window here is the middle of the day, not the evening: 11am–2pm runs 76.2% on time against 92.9% for 8am–11am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 11am–2pm window is the busiest, with 1,311 flights scheduled in it.

Across the week, Wednesday is the strongest day at 85.4% on time and Sunday the weakest at 79.9%. 6 points is a smaller lever than departure hour, but it is free.

Southwest leads United by 9 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

The largest share of delay minutes, 48%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 17,000 of the 35,000 delay minutes reported here. The split is drawn from 35,001 reported delay minutes.

Cancellations are rare at 0.69%, below the national 1.65% 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.

Badly late arrivals are rare here: only 2.4% land an hour or more behind schedule, against 9.7% 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.
