Follow DL1 in real time

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

DL1 is not transmitting right now. It may be between rotations, on the ground, or out of receiver range - Check back near 19:00 at JFK. The full map has the rest of the sky.

  • Your watch: set it 5 hours forward on arrival.
  • Window seat tip: the right (south-facing) side gets the sun on a daytime flight.
  • 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.

DL1 route overview: JFK to LHR

DL1 distance and great-circle path

DL1 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 DL1 block time differs from cruise time

The schedule allows 7.1 hours from gate to gate. That works out to about 782 km/h. An Airbus A330-900neo 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 Airbus A330-900neo comfortably fly DL1?

Not at all. At roughly 42% of its range, this is an easy trip for an Airbus A330-900neo. The airline picked it for cabin size, not distance. The full numbers are on our aircraft page for the Airbus A330-900neo.

What to know about DL1

  • 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.

DL1 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 only one flown with an Airbus A330-900neo.

Measured against DL1, which pushes back at 19:00:

  • AA100 (American Airlines) leaves 50 minutes earlier and is scheduled 5 minutes slower, on a Boeing 777-300ER.
  • BA112 (British Airways) leaves 30 minutes earlier and is scheduled 5 minutes quicker, on a Boeing 777-300ER.
  • B6007 (JetBlue Airways) leaves 3 hours later and is scheduled 5 minutes slower, 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.

DL1 activity in the past 7 days

Our database contains 2 observations of DL1 across 2 UTC dates in this window, most recently 2026-07-29. Those records contain 2 distinct transponder addresses.

The median recorded visibility was 241 minutes. That is time inside receiver coverage, not airborne duration or an on-time-performance measurement.
