British Airways has retained its crown as the quietest airline at Heathrow in the airport's latest noise league table.
The carrier was top for short haul flights and seventh for long haul in the chart, covering the three months from July to September.
El Al was the worst offender out of the top 50 airlines using Heathrow. It replaced Polish carrier Lot, which climbed one place to 49th.
The quarterly Fly Quiet table ranks airlines on six categories to determine how much disturbance they cause those living under the flight paths.
Each airline is rated from red to green for categories including the number of night flights operated, how quiet its planes are and how often it uses steeper descents to reduce noise on the ground.
Heathrow received a red mark for the number of planes landing before 6am but was rated green for all other criteria.
El Al was rated red for the number of 'Continuous Descent Approach' (CDA) violations, which is when planes do not land in such a way as to minimise noise, and amber in two categories related to the noise of its fleet.
The biggest climber in the table was Austrian Airline, which rose five places to 35th.
Heathrow introduced the table just over a year ago in an attempt to encourage airlines to improve their noise performance, and to shame those which didn't.
Heathrow chief executive John Holland-Kaye has written to airlines failing to meet Heathrow's CDA standards and the airport said it would work with carriers missing performance targets to help them improve their rating.
Matt Gorman, Heathrow's director of sustainability, said: "Since the inception of the Fly Quiet League, we have been able to rely on the continued good performance of the airlines who consistently dominate the top ranks of the table.
"However, we also want to highlight and encourage those that have made an improvement to the way they operate, and will help them to continue this trend. We believe it is only by working proactively with our partners that Heathrow airport can be a better, quieter neighbour to local residents."
