Historical statistics for July 2025 to June 2026, not live status. For today’s UA 1776, check with United Airlines.
UA 1776 draws a D. Roughly one flight in two arrives at least 15 minutes late, and the typical late arrival is a little over an hour behind schedule. Build slack into anything you connect to. That rests on 364 flights, with a median arrival 7 minutes late.
The national on-time rate over the same period is 77.6%, so UA 1776 runs 19 points behind the country as a whole. Across a thousand flights that is about 193 extra late arrivals.

These figures cover 364 flights between July 2025 and June 2026. Beyond the headline rate, 17.9% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule
When UA 1776 flies
UA 1776 flies ORD to PHL without a single fixed slot. Its most common scheduled departure was 18:20, used on 155 of 364 flights, with 18:08 (56 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 18:20 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and UA 1776 runs 10 points worse at 58.3%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
UA 1776 quarter by quarter
UA 1776 did not run the same all year. Its best quarter was Oct–Dec 2025 at 68.9% on time and its weakest Jan–Mar 2026 at 50.0%, a swing of 19 points on roughly 91 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, UA 1776 did best on Tuesday at 67.9% on time and worst on Sunday at 52.0%. Each day rests on about 52 flights, so a gap of 16 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 1776 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 60% of the 12,000 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.
- 60%Late-arriving aircraft
- 17%Carrier
- 17%National Airspace System
- 6%Extreme weather
60% 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 12,000 reported delay minutes here, that single category outweighs weather by 9 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 12,112 delay minutes reported on UA 1776.
Cancellations sit at 1.92% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 17.9% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum 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. 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 seven 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. 17.9% 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.
