There are far more rigorous environmental controls ( emissions, noise etc) on the aviation sector compared to other transport methods. As I said in my earlier post #4, to me the noise, road rage, pollution from cars on my road is more of an issue than aircraft noise & pollution.
Airlines, tour operators/air industry do not make huge profits, their profit margins are very tight. They make approximately £3 profit from each passenger ( figures from last year). Airlines also carry a lot of freight & overall they contribute £52 billion to the UK economy & provide lots of jobs. Foreign visitors coming over to the UK by air contribute around £17 billion to the UK economy each year. So there are huge economic benefits.
There are also social benefits - they carry us to our holidays & for us to meet our friends and relatives . Last year half of the UK population took at least one trip by air & around a quarter flying three or more times a year.
There are great social and economic benefits of aviation & I for one am fully supportive of this industry.
