Hello there

Having a cabin crew course or aviation course  is a positive side for the resume point of few but  it doesn't ensure ones job .Every Airlines train their crew as a fresher whether you have done the course or not .Also if one has done the course then it will be more comfortable for him/her to join unlike the others . If you have chance to join any course you can as it will help you during the training of the work.

Moreover,this sector has more population so it is very competitive area .So if you find the course ,do it .

All the best

Yeah! Its important to do a cabin crew course because the Airlines company ask for highly qualified individual including GCSEs in maths and English, or equivalent qualifications. So joining a institute is important for cabin crew because you learn so more things and get a degree. You can join any diploma programme.

To have a great future prospect you should get admitted to a course which will train you better as well as your skills will be brushed up.
