Ehm not entirely sure what it means with codeshare, but when looking up InterJet they state that they have "Interlinear agreements" with LH. They only have codeshare with AA, Latam, and Iberia.
Does this make any difference? The details for this is on their webpage which I am not allowed to write in this post. It is interjet .com/ en-us / interjet-experience / alliances / airline-companies
