==Environmental impact==
[[Greenhouse gas|Greenhouse gases]], mainly carbon dioxide, are emitted from aircraft due to burning fuel. About 2% of global carbon emissions are produced by [[aviation]] industry. 

Flying business class results in greater emissions than flying in economy-class seating, in part due to the amount of space associated with it. 

For long-haul flights, carbon emissions per passenger per kilometre travelled are about three times higher for business class and four times higher for first class, according to the Department for Business, Energy and Industrial Strategy (BEIS).

The length of the flight impacts the environment: as most emissions are generated through the takeoff phase in a plane's journey, it means short-haul flights are more impactful on the environment, as a larger proportion of the journey is in this phase. Whereas for longer haul flights, the plane is cruising for a longer proportion of the journey, making it less impactful on the environment than a short-haul flight, but it is still causing emissions. Transfer flights or routes that encompass multiple connecting flights also increase emissions as the takeoff phase is repeated. Private jets are also problematic, as emissions are generated for only a small number of people. <ref>{{Cite news |date=2019-08-23 |title=Climate change: Should you fly, drive or take the train? |language=en-GB |work=BBC News |url=https://www.bbc.com/news/science-environment-49349566 |access-date=2023-11-22}}</ref>
