It doesn’t sound like a job for an ehrliche Yid in the first place, precisely because of the type of problem you mentioned. And I’m sure there are many other problematic banners that people might want you to fly.
I also wonder if it’s even possible for a Shomer Shabbos Yid to have such a job. I think someone told me that it would be hard to find a job as a Shomer Shabbos pilot. I wonder if this would be the same.
Bottom line: find another job!
