  • 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.

What we know about UA64

What flying EWR to LIS takes

It is a long-haul sector, a widebody route with a full night's flying time. United Airlines needs a widebody twinjet: the sector needs long-range tanks and a cabin crew rest provision, which rules out most single-aisle types. Eastbound, the jet stream is usually a tailwind, so the return leg against it tends to be the longer of the two. In daylight the sun sits on the right (south-facing) side of the cabin for most of the crossing.

How we verified this

The origin and destination on this page are the ones we verified for callsign UAL64 through adsbdb, not a schedule copied from elsewhere. We have logged it airborne on 17 days between 2026-09-20 and 2026-10-08. Across 3 recorded legs the typical departure falls around 01:00 UTC. Timings are observations, not an official operational status: always confirm with the airline before travelling.

This page was published from our own tracking record rather than a third-party schedule feed, so it grows as we see the flight again. The seven-day log below is the raw version of the same evidence.

UA64 activity in the past 7 days

Our database contains 7 observations of UA64 across 7 UTC dates in this window, most recently 2026-10-08. Those records contain 3 distinct transponder addresses. The most frequently resolved route was EWR-LIS (7 records).

The median recorded visibility was 375 minutes. That is time inside receiver coverage, not airborne duration or an on-time-performance measurement.

How much CO2 does UA64 emit?

Worked from the great-circle distance and the fuel burn measured for Boeing 787-10, the aircraft normally flying this route. Carbon dioxide only - see the method below.

Distance flown5,434 km
AircraftBoeing 787-10 Dreamliner
Fuel burn rate6.1 kg per km
Fuel burned33,153 kg
CO2, whole flight104.8 tonnes
Seats, typical layout330
Passengers carried274 at an 83% load factor
CO2 per passenger382 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 382 kg cabin average and a flat bed well above it.

Economy271 seats, 225 flown
277 kg CO2 per seat
Business50 seats, 42 flown
802 kg CO2 per seat
First10 seats, 8 flown
1,106 kg CO2 per seat

Taken whole, UA64 emits what 1,746 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 2,249 km, or 10,924 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 5,434 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 UA64 against another flight.
