Delay causes
Why UA 1752 runs late
National Airspace System accounts for 42% of the 7,137 delay minutes carriers reported here, and the remaining four split what is left.
- 42%National Airspace System
- 38%Late-arriving aircraft
- 18%Carrier
- 2%Extreme weather
38% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,137 reported delay minutes here, that single category outweighs weather by 19 to one. The split is drawn from 7,137 delay minutes reported on UA 1752.
Cancellations are rare at 0.37%, 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
16.5% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 925 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 PBI to IAH (208), LGA to IAH (32) and PHX to IAH (21), but none flew often enough under UA 1752 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IAH to ORD only.
One caution: this is a thin sample. 270 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 1752
For a booking, UA 1752 is a flight to put a long connection behind. 16.5% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
