I'm wondering if anyone actually succeeded in getting an E3 petition approved for a flight crew job. The reason for this is that the E3 requirements not only demand that the beneficiary holds a Bachelor's degree or equivalent, but that the job itself is a specialty occupation which requires the worker to have a Bachelor's degree.
“specialty occupation” means an occupation that requires the theoretical and practical application of a body of highly specialized knowledge, and attainment of a bachelor’s or higher degree in the specific specialty (or its equivalent) as a minimum for entry into the occupation.
