Share of 355 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 139 departures that left 15 minutes late or more, only 11 made it up before arrival. In the other direction, 31 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at PHL.

Delay causes
Why UA 1776 runs late
Late-arriving aircraft accounts for 62% of the 14,000 delay minutes carriers reported here, and the remaining four split what is left.
- 62%Late-arriving aircraft
- 22%National Airspace System
- 13%Carrier
- 3%Extreme weather
62% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 14,000 reported delay minutes here, that single category outweighs weather by 19 to one. The split is drawn from 13,647 delay minutes reported on UA 1776.
Cancellations sit at 2.47% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
20.0% 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 678 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 six other city pairs in the data, including PSP to ORD (45), PNS to ORD (36) and SFO to PSP (21), but none flew often enough under UA 1776 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to PHL only.
One caution: this is a thin sample. 364 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 1776
For a booking, UA 1776 is a flight to put a long connection behind. 20.0% 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.
