These figures cover 320 flights between July 2025 and June 2026. The median arrival is 6 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.

Schedule

When UA 2250 flies

UA 2250 flies SAT to IAD without a single fixed slot. Its most common scheduled departure was 11:58, used on 42 of 320 flights, with 12:01 (38 flights) and 12:12 (37 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

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

A 11:58 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and UA 2250 runs 13 points better at 91.4%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

UA 2250 quarter by quarter

Quarter by quarter UA 2250 held fairly steady: 90.4% in Jul–Sep 2025, 92.0% in Oct–Dec 2025, 87.5% in Jan–Mar 2026 and 95.7% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, UA 2250 ranged from 86.5% on Monday to 96.0% on Thursday. With about 46 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why UA 2250 runs late

One category carries most of the weight here. Carrier accounts for 44% of the 1,934 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Carrier
44%
Late-arriving aircraft
39%
National Airspace System
16%

39% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 1,934 reported delay minutes here, that single category outweighs weather by 39 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 1,934 delay minutes reported on UA 2250.

Cancellations are rare at 0.62%, below the national 1.81% 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

Badly late arrivals are rare here: only 1.3% land an hour or more behind schedule, against 8.1% 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 1,362 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The same number turns up on two other city pairs in the data, including IAH to SAT (157) and IAD to SFO (34), but none flew often enough under UA 2250 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SAT to IAD only.

One caution: this is a thin sample. 320 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 2250

For a booking, UA 2250 has one of the better records a US domestic flight can show: 91.4% on time and 0.62% cancelled. That is a base rate, not a promise about any single day.
