Follow AY1331 in real time

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

AY1331 is not transmitting right now. It may be between rotations, on the ground, or out of receiver range - Check back near 08:00 at HEL. The full map has the rest of the sky, and what is flying over me will name whatever is above you instead.

AY1331 at a glance

  • How long: 3h 10m gate to gate. That is about 583 km/h on average, taxi time included.
  • Your watch: set it 2 hours back on arrival.
  • Window seat tip: the left (south-facing) side gets the sun on a daytime flight.
  • The plane: usually an Airbus A321. This route uses about 31% of how far it can fly.
  • When it goes: out of HEL in early morning, into LHR in mid-morning.

AY1331 route overview: HEL to LHR

AY1331 distance and great-circle path

AY1331 covers 1,848 km, or 1,148 miles. That makes it a medium-haul flight, long enough for a full meal service, short enough for narrowbodies. Of the 439 routes we track, it ranks 330 by distance.

The plane leaves Helsinki heading 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 HEL-LHR route appears on a tracker map.

Why AY1331 block time differs from cruise time

The schedule allows 3.2 hours from gate to gate. That works out to about 583 km/h. An Airbus A321 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 why long flights take odd-looking routes.

Can the Airbus A321 comfortably fly AY1331?

Not at all. At roughly 31% of its range, this is an easy trip for an Airbus A321. The airline picked it for cabin size, not distance. The full numbers are on our aircraft page for the Airbus A321.

What to know about AY1331

  • Time change: you land 2 hours behind the time you left.
  • Flies far north: the real path runs much closer to the pole than a flat map suggests.

How much CO2 does AY1331 emit?

Worked from the great-circle distance and the fuel burn measured for Airbus A321-200, the aircraft normally flying this route. Carbon dioxide only - see the method below.

Distance flown1,848 km
AircraftAirbus A321
Fuel burn rate3.61 kg per km
Fuel burned6,671 kg
CO2, whole flight21.1 tonnes
Seats, typical layout185
Passengers carried154 at an 83% load factor
CO2 per passenger137 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 137 kg cabin average and a flat bed well above it.

Economy163 seats, 135 flown
113 kg CO2 per seat
Business22 seats, 18 flown
327 kg CO2 per seat

Taken whole, AY1331 emits what 351 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 805 km, or 3,911 km of the same journey by train.

How this is worked out. Fuel burn is read from published measurements of this type, taken at a 0 km sector, the only published sector for this type, applied to this route's 1,848 km unadjusted. 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 AY1331 against another flight.

Data sources and review

Reviewed 2026-07-29 by Flight-Tracker.net Editorial Team

The route and typical schedule are maintained reference data. Live ADS-B observations are evidence of receiver coverage, not proof of on-time performance. Always confirm the operating date and times with the airline.
