Original Note:
This is normal. The length of time that a contrail lasts is directly proportional to the amount of humidity that is already in the air. The newly formed ice particles, from the jet exhaust, will continue to grow in size by taking water from the surrounding atmosphere. https://www.weather.gov/fgz/CloudsContrails# https://www.faa.gov/sites/faa.gov/files/regulations_policies/policy_guidance/envir_policy/contrails.pdf
