Delay causes

Why UA 1170 runs late

Late-arriving aircraft accounts for 63% of the 7,735 delay minutes carriers reported here, and the remaining four split what is left.

  • Late-arriving aircraft
    63%
  • Carrier
    32%
  • National Airspace System
    5%

63% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,735 reported delay minutes here, that single category outweighs weather by 63 to one. The split is drawn from 7,735 delay minutes reported on UA 1170.

Cancellations are rare at 0.55%, 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

9.9% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.

At 2,556 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

The same number turns up on two other city pairs in the data, including ORD to LAX (21) and BOS to ORD (12), but none flew often enough under UA 1170 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LAX to HNL only.

One caution: this is a thin sample. 365 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 UA 1170
