Is it obligatory to leave the job of a flight attendant, and what is the ruling on the money earned from it, given justifications for continuing the work such as the unavailability of a suitable alternative, linguistic expertise, promotions, and safe travel that does not require a mahram, knowing that I try as much as possible to avoid aspects that violate Sharia?

A Muslim's work supervising the serving of forbidden items such as intoxicants and pork is legally prohibited. The supervisor of a transgression is a partner in responsibility, and this is considered cooperation in sin and aggression, which Allah and His Messenger (peace be upon him) have forbidden.

Furthermore, a woman's work as a flight attendant or supervisor on an airplane involves other prohibitions, such as being alone with men (khalwa), excessive intermingling, and clothing that violates Islamic law, all of which further increase the prohibition of this work.

The jurists have stipulated the prohibition of aiding in disobedience and that money earned from a forbidden occupation is not permissible to benefit from; it must be given in charity, and one must repent from that work.

Therefore, a Muslim woman should reconsider this "dream job," which may cause regret and remorse in the afterlife, and seek permissible work that pleases Allah. True happiness lies in Allah's pleasure, and whoever fears Allah, He will make a way out for him and provide for him from where he does not expect.
