increased plane noise in Teddington

[londoniana]

Is this normal or a recent increase in airplane noise, especially during the evenings? We moved to Teddington at the end of May and I don't remember June being so noisy.

Any special reason for this? Do they alternate flightpaths by month?

They are doing a trial using both runways for take off and landing so they can get more planes in the same slots.just wait till they announce the 3 rd runway after the next election delightful
