El Al, the flagship airline carrier for Israel, has been ranked as the noisiest and dirtiest airlines operating in and out of Heathrow airport, according to this report by Heathrow.
In a survey of 50 airlines using Heathrow – the busiest airport in Europe – Israel's national carrier came in last positon.
The airport analysed seven measures including noise, nitrogen oxide emissions, whether fights were late or early and efficient landing approaches. The data was based on flights from January-March and 24 of the 50 airlines failing at least one of those measurements.
By contrast, Etihad Airways from the UAE was announced among the cleanest and quietest airlines alongside British Airways and Aer Lingus.
The airport intends to name and shame the airlines in order to improve their performance. Its list, called the "Fly Quiet and Clean League Table" will be published every three months in a bid to encourage airlines to use more efficient planes at the airport.
The Israeli carrier heads the list of the worst performing which include Kuwait Airways, Middle East Airlines, Pakistan International Airlines, Omar Air and Jet Airways.
