LH400 route overview: FRA to JFK

LH400 distance and great-circle path

LH400 covers 6,189 km, or 3,845 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 185 by distance.

The plane leaves Frankfurt heading north-west. 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 FRA-JFK route appears on a tracker map.

Why LH400 block time differs from cruise time

The schedule allows 8.8 hours from gate to gate. That works out to about 707 km/h. A Boeing 747-8 cruises faster than that. The gap is taxi time, climbing, descending and holding.

Flying west, this route pushes against the wind. The trip back east is usually shorter, even though the distance is the same. See how high-altitude winds behave in our guide to turbulence and jet streams.

Can the Boeing 747-8 comfortably fly LH400?

Not at all. At roughly 43% of its range, this is an easy trip for a Boeing 747-8. The airline picked it for cabin size, not distance. The full numbers are on our aircraft page for the Boeing 747-8.

What to know about LH400

  • Time change: you land 5 hours behind the time you left. That is enough to cause jet lag. Here is how pilots handle it.

LH400 activity in the past 7 days

Our database contains 8 observations of LH400 across 8 UTC dates in this window, most recently 2026-10-29. Those records contain 4 distinct transponder addresses. The most frequently resolved route was FRA-JFK (8 records).

The median recorded visibility was 505 minutes. That is time inside receiver coverage, not airborne duration or an on-time-performance measurement.

How much CO2 does LH400 emit?

Worked from the great-circle distance and the fuel burn measured for Boeing 747-8, the aircraft normally flying this route. Carbon dioxide only - see the method below.

Distance flown6,189 km
AircraftBoeing 747-8
Fuel burn rate9.97 kg per km
Fuel burned61,728 kg
CO2, whole flight195.1 tonnes
Seats, typical layout410
Passengers carried340 at an 83% load factor
CO2 per passenger574 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 574 kg cabin average and a flat bed well above it.

Economy320 seats, 266 flown
388 kg CO2 per seat
Business70 seats, 58 flown
1,126 kg CO2 per seat
First20 seats, 17 flown
1,554 kg CO2 per seat

Taken whole, LH400 emits what 3,251 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 3,375 km, or 16,392 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 5,556 km, 11,112 km and 13,334 km, interpolated to this route's 6,189 km. 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 LH400 against another flight.
