If you are thinking about a career as a flight attendant or cabin crew member, timing matters. You should plan to start the Cabin Crew Course in Mumbai after completing your 10+2 education (high school). Most training institutes and programs, like the one described on this Cabin Crew Course in Mumbai page, require you to finish 12th grade or an equivalent qualification before you begin.
In general, starting as soon as you are eligible is a good idea. The usual eligibility criteria say you should be at least 17-18 years old and have completed class 12th from a recognized board. Some places prefer students who are a bit older, up to the mid-20s, but there is usually no advantage in waiting beyond eligibility unless you want more work or language experience first.
Starting early has many advantages. You join the course while you have fewer responsibilities and more time to focus on learning. The training covers skills like communication, safety procedures, customer service, emergency handling, aircraft familiarization, and grooming all essential for cabin crew jobs. You also get to enter the job market sooner, which means beginning your aviation career faster once you finish. Courses in Mumbai typically run nearly 11 months, so early entry helps you complete training without delay.
There are some downsides to consider too. If you start too early without clear focus, you might feel overwhelmed by training or struggle with confidence, especially in communication skills. Some students benefit from gaining extra language skills or customer service experience before starting the course. That extra preparation can make you more confident and job-ready.
