These figures cover 364 flights between September 2025 and August 2026. The median arrival is 10 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.

Across the year

UA 2663 quarter by quarter

Delay causes

Why UA 2663 runs late

Late-arriving aircraft accounts for 42% of the 4,542 delay minutes carriers reported here, and the remaining four split what is left.

  • Late-arriving aircraft
    42%
  • Carrier
    30%
  • National Airspace System
    28%
  • Extreme weather
    0%

42% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,542 reported delay minutes here, that single category outweighs weather by 42 to one. The split is drawn from 4,542 delay minutes reported on UA 2663.

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

5.6% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.

The same number turns up on one other city pair in the data, including ORD to EGE (8), but none flew often enough under UA 2663 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EGE to DEN only.

One caution: this is a thin sample. 364 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 2663

For a booking, read UA 2663 as 81.1% on time with 0.55% cancelled over 364 flights. Those are rates from the past twelve months, not a forecast for any particular day.
