          Heathrow Airport has a "dedicated website" for the planned creation of an additional runway. From the dedicated website (emphasis added):




          Heathrow Today




          • 98% capacity – Flight movements at Heathrow are capped at 480,000/year


          Heathrow Expansion:




          • 740,000 flight movements capacity




          Assuming the capacity in the expanded airport is still per year (as is explicitly stated on another Heathrow Airport website), there would be the capacity for an additional 260,000 flights per year. That is equivalent to ~712 flights per day offered by the additional capacity.



          OAG, "an air travel intelligence company," predicts a total of 140,556 air traffic movements (ATMs). Their report is pretty comprehensive and includes long-haul, short-haul, etc. A single departure (and arrival) counts as one ATM. Thus, the increase of 140,556 ATMs is equivalent to 385 additional flights per day. Equivalently, 54.1% of the additional capacity is expected to be used, and not 100%.



          To summarize:




          Would 700 more planes a day fly because of the Heathrow expansion, as the signs imply?




          Maybe. Probably not. The expansion will increase the airport capacity by 712 flights per day. This is not a guarantee that 712 extra flights will occur a day. In fact, an airline analysis company predicts just 385 additional flights per day. This figure is nowhere near 700.

            Yes, assuming that the airport continues to run at 98% capacity or higher.



            According to Heathrowexpansion.com (a site apparently also owned by the airport), the expansion would have a "740,000 flight movements capacity" (per year for three runways) while currently the capacity is 480,000/year. This makes the math to figure out the new cap (740,000-480,000)/365 which is about 712 flights per day more than the previous cap. If they run at 98% capacity that makes it 698 flights per day extra.

              But that's a big assumption to make when you've increased capacity by 50%.
