Follow AA100 in real time

The aircraft appears below whenever it is airborne and inside receiver coverage. Its planned route is drawn between the two airports.

AA100 is not transmitting right now. It may be between rotations, on the ground, or out of receiver range - Check back near 18:10 at JFK. The full map has the rest of the sky, and what is flying over me will name whatever is above you instead.

AA100 at a glance

  • The trip: 5,540 km (3,442 miles) from New York to London, flying north-east.
  • How long: 7h 10m gate to gate. That is about 773 km/h on average, taxi time included.
  • Your watch: set it 4 hours forward on arrival.
  • Window seat tip: the right (south-facing) side gets the sun on a daytime flight.
  • The plane: usually a Boeing 777-300ER. This route uses about 41% of how far it can fly.
  • When it goes: out of JFK in the early evening, into LHR in early morning. It is an overnight, so most of the cabin will try to sleep.

AA100 route overview: JFK to LHR

AA100 distance and great-circle path

AA100 covers 5,540 km, or 3,442 miles. That makes it a long-haul flight, a widebody route with a full night's flying time. Of the 439 routes we track, it ranks 212 by distance.

The plane leaves New York heading north-east. On the map above, the line looks curved. That is normal. The shortest path over a round planet never looks straight on a flat screen. Our guide explains how the JFK-LHR route appears on a tracker map.

Why AA100 block time differs from cruise time

The schedule allows 7.2 hours from gate to gate. That works out to about 773 km/h. A Boeing 777-300ER cruises faster than that. The gap is taxi time, climbing, descending and holding.

Flying east, this route usually picks up tailwinds high up. The flight back west normally takes longer, even though the distance is identical. See how timing changes the trip in our red-eye flight guide.

Can the Boeing 777-300ER comfortably fly AA100?

Not at all. At roughly 41% of its range, this is an easy trip for a Boeing 777-300ER. The airline picked it for cabin size, not distance. The full numbers are on our aircraft page for the Boeing 777-300ER.

What to know about AA100

  • Time change: you land 4 hours ahead of the time you left.

AA100 against the rest of the JFK-LHR pairing

We track 4 scheduled services between New York and London, flown by 4 different carriers. Among them, it is the first departure of the day on this route; it is given 10 minutes more block time than the quickest scheduled service.

Measured against AA100, which pushes back at 18:10:

  • BA112 (British Airways) leaves 20 minutes later and is scheduled 10 minutes quicker, on the same Boeing 777-300ER.
  • DL1 (Delta Air Lines) leaves 50 minutes later and is scheduled 5 minutes quicker, on an Airbus A330-900neo.
  • B6007 (JetBlue Airways) leaves 3 hours 50 minutes later and is given the same block time, on an Airbus A321LR.

Block time is gate to gate, so it counts taxi at both ends. That is why two flights covering identical distance rarely share a scheduled duration.

AA100 activity in the past 7 days

Our database contains 8 observations of AA100 across 8 UTC dates in this window, most recently 2026-10-29. Those records contain 7 distinct transponder addresses. The most frequently resolved route was JFK-LHR (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 AA100 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 flown5,540 km
AircraftBoeing 777-300ER
Fuel burn rate8.86 kg per km
Fuel burned49,079 kg
CO2, whole flight155.1 tonnes
Seats, typical layout365
Passengers carried303 at an 83% load factor
CO2 per passenger512 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 512 kg cabin average and a flat bed well above it.

Economy299 seats, 248 flown
372 kg CO2 per seat
Business55 seats, 46 flown
1,078 kg CO2 per seat
First11 seats, 9 flown
1,486 kg CO2 per seat

Taken whole, AA100 emits what 2,585 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 3,011 km, or 14,624 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 AA100 against another flight.
