Nonstop flight route between London, England, United Kingdom and Portland, Maine, United States:

About this route:

A direct, nonstop flight between London Heathrow Airport (LHR), London, England, United Kingdom and Portland International Jetport (PWM), Portland, Maine, United States would travel a Great Circle distance of 3,175 miles (or 5,110 kilometers).

A Great Circle is the shortest distance between 2 points on a sphere. Because most world maps are flat (but the Earth is round), the route of the shortest distance between 2 points on the Earth will often appear curved when viewed on a flat map, especially for long distances. If you were to simply draw a straight line on a flat map and measure a very long distance, it would likely be much further than if you were to lay a string between those two points on a globe. Because of the large distance between London Heathrow Airport and Portland International Jetport, the route shown on this map most likely appears curved because of this reason.

Try it at home! Get a globe and tightly lay a string between London Heathrow Airport and Portland International Jetport. You'll see that it will travel the same route of the red line on this map!

Facts about London Heathrow Airport (LHR):

• With only two runways, operating at over 98% of their capacity, Heathrow has little room for more flights, although the increasing use of larger aircraft such as the Airbus A380 will allow some increase in passenger numbers.
• When runway alternation was introduced, aircraft generated significantly more noise on departure than when landing, so a preference for westerly operations during daylight was introduced, which continues to this day.
• London Heathrow Airport (LHR) has 2 runways.
• Because of London Heathrow Airport's relatively low elevation of 83 feet, planes can take off or land at London Heathrow Airport at a lower air speed than at airports located at a higher elevation. This is because the air density is higher closer to sea level than it would otherwise be at higher elevations.
• The closest airport to London Heathrow Airport (LHR) is RAF Northolt (NHT), which is located only 6 miles (9 kilometers) NNE of LHR.
• Full body scanners are now used at the airport, and passengers who object to their use after being selected are not allowed to fly.
• Heathrow Airport has Anglican, Catholic, free church, Hindu, Jewish, Muslim and Sikh chaplains.
• As the airport is west of London and as its runways run east–west, an airliner's landing approach is usually directly over the conurbation of London when the wind is from the west.
