Original Note:
How long a contrail lasts depends on how dry or how humid the air is. If the air is very dry, they will dissipate quickly. If the air is humid, they will stay where they are. Trails may last for many hours leaving the sky criss-crossed with lines, and mixing with cirrus cloud. https://www.metoffice.gov.uk/weather/learn-about/weather/types-of-weather/clouds/other-clouds/contrails
