These figures cover 293 flights between September 2025 and August 2026. The median arrival is 17 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 UA 1234 runs late
Carrier accounts for 87% of the 1,540 delay minutes carriers reported here, and the remaining four split what is left.
- 87%Carrier
- 13%National Airspace System
The largest share of delay minutes, 87%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,337 of the 1,540 delay minutes reported here. The split is drawn from 1,540 delay minutes reported on UA 1234.
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 836 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 CHS to EWR (31), DEN to DCA (24) and LGA to ORD (14), but none flew often enough under UA 1234 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to GEG to DEN only.
One caution: this is a thin sample. 293 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 1234
For a booking, UA 1234 has one of the better records a US domestic flight can show: 96.2% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
