What we know about UA2437

What flying LGA to DEN takes

It is a medium-haul sector, long enough for a full meal service, short enough for narrowbodies. United Airlines needs a narrowbody on the longer variants, or a widebody where demand justifies it: at this distance the choice is usually about seat count rather than range. The two ends are not symmetric. Denver is roughly 5,413 ft higher than the other airport, so the same aircraft is planned differently in each direction. In daylight the sun sits on the left (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 UAL2437 through adsbdb, not a schedule copied from elsewhere. We have logged it airborne on 36 days between 2026-09-19 and 2026-10-24. 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.

UA2437 activity in the past 7 days

Our database contains 8 observations of UA2437 across 8 UTC dates in this window, most recently 2026-10-24. Those records contain 7 distinct transponder addresses. The most frequently resolved route was LGA-DEN (8 records).

The median recorded visibility was 1435 minutes. That is time inside receiver coverage, not airborne duration or an on-time-performance measurement.

How much CO2 does UA2437 emit?

Worked from the great-circle distance and the fuel burn measured for Boeing 737-900ER, the aircraft normally flying this route. Carbon dioxide only - see the method below.

Distance flown2,600 km
AircraftBoeing 737-900ER
Fuel burn rate3.83 kg per km
Fuel burned9,955 kg
CO2, whole flight31.5 tonnes
Seats, typical layout178
Passengers carried148 at an 83% load factor
CO2 per passenger213 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 213 kg cabin average and a flat bed well above it.

Economy157 seats, 130 flown
175 kg CO2 per seat
Business21 seats, 17 flown
509 kg CO2 per seat

Taken whole, UA2437 emits what 524 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 1,250 km, or 6,073 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 926 km sector, the only published sector for this type, applied to this route's 2,600 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 UA2437 against another flight.
