Obviously the movie for all its strengths and beautiful flying is still sexist. When showing it to my kids I simply disclosed it’s how things used to be and it wasn’t right and things are better now. And we need to keep them better.
What is the sexist part? That two men have a fight to marry a female airplane engineer/mechanic? That a woman runs a restaurant and is holding out for some man?
Doesn't seem like a sexist movie to me, despite the fact that it depicts sexism. Maybe you didn't notice the difference?
