To become an air hostess (flight attendant), you are generally required to be fluent in at least one language: English, which is the universal language of aviation. However, most international airlines require or strongly prefer fluency in a second language, typically the native language of the airline's home country (e.g., German for Lufthansa, French for Air France). For "Language Qualified" (LQ) positions, airlines often seek candidates who speak three or more languages, such as Mandarin, Spanish, or Arabic, to serve diverse routes. While you don't necessarily need five languages to get hired, being bilingual is often the minimum barrier to entry for top-tier international carriers. Language proficiency is usually tested during the interview process through both written exams and oral "check-rides" to ensure you can communicate safety instructions clearly.
