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 255 routes we track, it ranks 154 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 5 hours ahead of the time you left. That is enough to cause jet lag. Here is how pilots handle it.

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.
