These figures cover 295 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.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 07:26 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and OO 5542 runs level with that at 87.5%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Delay causes

Why OO 5542 runs late

Carrier accounts for 87% of the 1,691 delay minutes carriers reported here, and the remaining four split what is left.

  • Carrier
    87%
  • National Airspace System
    13%

The largest share of delay minutes, 87%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,468 of the 1,691 delay minutes reported here. The split is drawn from 1,691 delay minutes reported on OO 5542.

Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are 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 1.7% 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 same number turns up on three other city pairs in the data, including ORD to FAR (32), ORD to GRB (23) and IAH to OKC (1), but none flew often enough under OO 5542 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to PSP to LAX only.

One caution: this is a thin sample. 295 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 5542

For a booking, OO 5542 has one of the better records a US domestic flight can show: 87.5% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
