These figures cover 295 flights between September 2025 and August 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.

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 4 March 2026 | 3 hours 38 minutes | Carrier |

Delay causes
Why UA 2242 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 2,159 reported delay minutes.
- 38%Carrier
- 32%Late-arriving aircraft
- 29%National Airspace System
- 1%Extreme weather
The largest share of delay minutes, 38%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 812 of the 2,159 delay minutes reported here. The split is drawn from 2,159 delay minutes reported on UA 2242.
Cancellations are rare at 0.34%, 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
Badly late arrivals are rare here: only 2.7% 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 1,195 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 five other city pairs in the data, including ORD to LAS (46), LGA to IAH (21) and SLC to EWR (19), but none flew often enough under UA 2242 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IAH to SLC only.
One caution: this is a thin sample. 295 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 2242
For a booking, UA 2242 has one of the better records a US domestic flight can show: 86.0% on time and 0.34% cancelled. That is a base rate, not a promise about any single day.
