What we know about UA2804

What flying IAD to EWR takes

This is a short hop, and the economics work differently: turnaround time dominates the economics; the aircraft may fly this sector four or five times a day. United Airlines would normally roster a regional jet or a small narrowbody for it. 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 UAL2804 through adsbdb, not a schedule copied from elsewhere. We have logged it airborne on 33 days between 2026-09-19 and 2026-10-21. 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.

UA2804 activity in the past 7 days

Our database contains 7 observations of UA2804 across 7 UTC dates in this window, most recently 2026-10-21. Those records contain 7 distinct transponder addresses. The most frequently resolved route was IAD-EWR (7 records).

The median recorded visibility was 112 minutes. That is time inside receiver coverage, not airborne duration or an on-time-performance measurement.

How much CO2 does UA2804 emit?

Worked from the great-circle distance and the fuel burn measured for Boeing 737 MAX 8, the aircraft normally flying this route. Carbon dioxide only - see the method below.

Distance flown340 km
AircraftBoeing 737 MAX 8
Fuel burn rate3.04 kg per km
Fuel burned1,033 kg
CO2, whole flight3.3 tonnes
Seats, typical layout162
Passengers carried134 at an 83% load factor
CO2 per passenger24 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 24 kg cabin average and a flat bed well above it.

Economy143 seats, 119 flown
20 kg CO2 per seat
Business19 seats, 16 flown
57 kg CO2 per seat

Taken whole, UA2804 emits what 54 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 143 km, or 696 km of the same journey by train.

How this is worked out. Fuel burn is read from published measurements of this type, taken at a 1,222 km sector, the only published sector for this type, applied to this route's 340 km unadjusted. 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 UA2804 against another flight.
