I was not familiar with Condor Airlines so I did a bit of research. Condor was founded in 1956 in Germany. According to it’s website, it’s Germany’s “most popular leisure airline”. The unique strips livery was introduced in 2022 to “Introduce a new brand identity: Inspired by parasols, bath towels and beach chairs, Condor now wears stripes in five colors. This illustrates the development from a leisure airline to a unique and unmistakable vacation brand.” The green and white livery in the photo I captured is their Island color theme.
