These figures cover 353 flights between September 2025 and August 2026. The median arrival is 18 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.

UA 1450 is scheduled to leave Washington (DCA) at 06:00 local time and reach Houston (IAH) at 08:13. That slot held for 353 of the 353 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

- 68%Carrier
- 30%National Airspace System
- 2%Extreme weather
The largest share of delay minutes, 68%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,086 of the 1,600 delay minutes reported here. The split is drawn from 1,600 delay minutes reported on UA 1450.
Cancellations sit at 1.13% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 0.9% 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 1,208 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 eight other city pairs in the data, including IAH to DEN (111), DEN to SFO (33) and IAH to SNA (31), but none flew often enough under UA 1450 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DCA to IAH only.
One caution: this is a thin sample. 353 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 1450
For a booking, UA 1450 has one of the better records a US domestic flight can show: 92.8% on time and 1.13% cancelled. That is a base rate, not a promise about any single day.
