What to know about UA958

  • Time change: you land 6 hours ahead of the time you left. That is enough to cause jet lag. Here is how pilots handle it.

What we know about UA958

What flying ORD to LHR takes

It is a long-haul sector, a widebody route with a full night's flying time. United Airlines needs a widebody twinjet: the sector needs long-range tanks and a cabin crew rest provision, which rules out most single-aisle types. Eastbound, the jet stream is usually a tailwind, so the return leg against it tends to be the longer of the two. In daylight the sun sits on the right (south-facing) side of the cabin for most of the crossing.

How we verified this

The origin and destination on this page are the ones we verified for callsign UAL958 through adsbdb, not a schedule copied from elsewhere. We have logged it airborne on 46 days between 2026-09-20 and 2026-11-04. Timings are observations, not an official operational status: always confirm with the airline before travelling.

This page was published from our own tracking record rather than a third-party schedule feed, so it grows as we see the flight again. The seven-day log below is the raw version of the same evidence.

UA958 activity in the past 7 days

Our database contains 8 observations of UA958 across 8 UTC dates in this window, most recently 2026-11-04. Those records contain 7 distinct transponder addresses. The most frequently resolved route was ORD-LHR (8 records).

The median recorded visibility was 523 minutes. That is time inside receiver coverage, not airborne duration or an on-time-performance measurement.

How much CO2 does UA958 emit?

Worked from the great-circle distance and the fuel burn measured for Boeing 767-300ER, the aircraft normally flying this route. Carbon dioxide only - see the method below.

Distance flown6,345 km
AircraftBoeing 767-300ER
Fuel burn rate5.39 kg per km
Fuel burned34,181 kg
CO2, whole flight108.0 tonnes
Seats, typical layout218
Passengers carried181 at an 83% load factor
CO2 per passenger597 kg

Where that lands by cabin

The aircraft burns the same fuel whoever is aboard, so the cabins divide one total rather than each carrying their own. A seat's share is the floor it takes up, which is why an economy seat comes out below the 597 kg cabin average and a flat bed well above it.

Economy179 seats, 149 flown
430 kg CO2 per seat
Business33 seats, 27 flown
1,246 kg CO2 per seat
First7 seats, 6 flown
1,719 kg CO2 per seat

Taken whole, UA958 emits what 1,800 trees take back out of the air in a year. One economy seat on it accounts for about the same carbon dioxide as driving a petrol car 3,510 km, or 17,050 km of the same journey by train.

How this is worked out. Fuel burn is read from published measurements of this type, taken at sectors of 3,984 km and 5,556 km, all shorter than this route, so the closest is held flat and the real figure is likely a little higher. It counts carbon dioxide only, and the cabin split assumes the layout typical of this size of aircraft. Read the full method, sources and caveats, or put UA958 against another flight.
