SQ12 route overview: NRT to LAX

SQ12 distance and great-circle path

SQ12 covers 8,753 km, or 5,439 miles. That makes it a long-haul flight, a widebody route with a full night's flying time. Of the 299 routes we track, it ranks 105 by distance.

Tokyo to Los Angeles crosses the international date line. The 8,753 km track runs north-east, and the calendar date at the gate in Los Angeles will not be the one the cabin expects. It links Japan with United States.

Our guide explains how the NRT-LAX route appears on a tracker map.

Can the Boeing 777-300ER comfortably fly SQ12?

Not really. It uses about 64% of the Boeing 777-300ER's range. That leaves room for a full load of passengers and bags. The full numbers are on our aircraft page for the Boeing 777-300ER.

What we know about SQ12

What flying NRT to LAX takes

It is a long-haul sector, a widebody route with a full night's flying time. Singapore 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 SIA12 through adsbdb, not a schedule copied from elsewhere. We have logged it airborne on 14 days between 2026-09-19 and 2026-10-02. 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.

SQ12 activity in the past 7 days

Our database contains 8 observations of SQ12 across 8 UTC dates in this window, most recently 2026-10-02. Those records contain 7 distinct transponder addresses. The most frequently resolved route was NRT-LAX (8 records).

The median recorded visibility was 1054 minutes. That is time inside receiver coverage, not airborne duration or an on-time-performance measurement.

How much CO2 does SQ12 emit?

Worked from the great-circle distance and the fuel burn measured for Boeing 777-300ER, the aircraft normally flying this route. Carbon dioxide only - see the method below.

Distance flown	8,753 km
Aircraft	Boeing 777-300ER
Fuel burn rate	8.86 kg per km
Fuel burned	77,543 kg
CO2, whole flight	245.0 tonnes
Seats, typical layout	365
Passengers carried	303 at an 83% load factor
CO2 per passenger	809 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 809 kg cabin average and a flat bed well above it.

Economy299 seats, 248 flown

587 kg CO2 per seat

10 trees absorbing for a year

Business55 seats, 46 flown

1,702 kg CO2 per seat

28 trees absorbing for a year

First11 seats, 9 flown

2,348 kg CO2 per seat

39 trees absorbing for a year (first 30 shown)

Taken whole, SQ12 emits what 4,084 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 4,757 km, or 23,106 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 10,199 km, 11,112 km and 13,334 km, all longer 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 SQ12 against another flight.
