Historical statistics for July 2025 to June 2026, not live status. For today’s UA 2211, check with United Airlines.

UA 2211 earns an F, which is as low as this site's scale goes for a reason. Only 54.7% of flights arrive inside the 15-minute window, 23 points worse than the national rate of 77.6%. Late arrivals average about an hour. Treat any tight connection here as a coin flip. That rests on 294 flights, with a median arrival 10 minutes late.

The national on-time rate over the same period is 77.6%, so UA 2211 runs 23 points behind the country as a whole. Across a thousand flights that is about 229 extra late arrivals.

These figures cover 294 flights between July 2025 and June 2026. Beyond the headline rate, 13.1% 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 2211 flies

UA 2211 flies ORD to SEA without a single fixed slot. Its most common scheduled departure was 19:59, used on 69 of 294 flights, with 19:45 (44 flights) and 19:35 (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 19:59 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and UA 2211 runs 14 points worse at 54.7%. 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 2211 quarter by quarter

UA 2211 did not run the same all year. Its best quarter was Apr–Jun 2026 at 66.1% on time and its weakest Oct–Dec 2025 at 46.6%, a swing of 19 points on roughly 74 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 2211 did best on Wednesday at 60.0% on time and worst on Thursday at 47.5%. Each day rests on about 42 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 2211 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 43% of the 7,396 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.

Extreme weather

43% 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 7,396 reported delay minutes here, that single category outweighs weather by 5 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 7,396 delay minutes reported on UA 2211.

Cancellations sit at 1.70% 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. 13.1% 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.

At 1,721 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

The same number turns up on nine other city pairs in the data, including TPA to ORD (115), RSW to ORD (79) and JAX to ORD (62), but none flew often enough under UA 2211 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to SEA only.

One caution: this is a thin sample. 294 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 2211

For a booking, UA 2211 is a flight to put a long connection behind. 13.1% 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.
