How we verified this

The origin and destination on this page are the ones we verified for callsign MAS1437 through adsbdb, not a schedule copied from elsewhere. We have logged it airborne on 28 days between 2026-09-20 and 2026-10-17. 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.

MH1437 activity in the past 7 days

Our database contains 7 observations of MH1437 across 7 UTC dates in this window, most recently 2026-10-17. Those records contain 7 distinct transponder addresses. The most frequently resolved route was LGK-KUL (7 records).

The median recorded visibility was 50 minutes. That is time inside receiver coverage, not airborne duration or an on-time-performance measurement.

How much CO2 does MH1437 emit?

Worked from the great-circle distance and the fuel burn measured for Boeing 737-800, the aircraft normally flying this route. Carbon dioxide only - see the method below.

Distance flown455 km
AircraftBoeing 737-800
Fuel burn rate3.59 kg per km
Fuel burned1,632 kg
CO2, whole flight5.2 tonnes
Seats, typical layout162
Passengers carried134 at an 83% load factor
CO2 per passenger38 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 38 kg cabin average and a flat bed well above it.

Economy143 seats, 119 flown
31 kg CO2 per seat
Business19 seats, 16 flown
90 kg CO2 per seat

Taken whole, MH1437 emits what 86 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 226 km, or 1,099 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 455 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 MH1437 against another flight.
