Original Note:
A difference in flight level of 1,000 feet is enough for one aircraft to cause a contrail and the other not. In addition, contrails of more efficient engines with cooler exhaust gases can form at lower altitudes than those of less efficient engines. https://www.gov.uk/government/publications/contrails-and-chemtrails-frequently-asked-questions/contrails#:~:text=A%20difference%20in%20flight%20level,those%20of%20less%20efficient%20engines.
