Diploma

Frankfinn should take your admission because you justify almost all the minimum requirements for becoming a cabin crew.
They are a grooming academy, and as per my knowledge they actually have no tie-ups with any airlines for recruitment.
They work as third party consultancy who connect you to the right people for interview.
In general Candidate Profile for Freshers for cabin crew is as under :
Age:Between 18 and 27 years
Minimum Height:Men - 170 cms and Women - 157 cms
Weight:In proportion to height
Educational Qualification:HSC (10 + 2). Candidates who are appearing for their HSC examinations can also apply
Physical features:Pleasing personality, clear complexion (scars, pimples and blemishes not acceptable) and good eyesight
Marital Status:Unmarried
Language skills:Fluency in English and Hindi. Proficiency in a foreign language will be an added advantage.
Interactive skills:Excellent communication and good interpersonal skills
Nationality:Indian citizens only
Passport:Must possess a valid Indian passport or should have applied for a passport
Mandatory Documentation :Must possess a Pan Card and Aadhaar Card
So that becomes very clear that it merely requires some grooming to get the job of a cabin crew. They don't demand much from candidates.
You should be interpersonally sound and capable to handle people from different cultures.
Cabin crew is the face of the airline. Coz they face the passengers for the first time.
Foreign languages like German, French, Russian, Arabic, Chinese and Japanese, Can allow you to get an edge over others.
As this allows the airline to roster you on routes where such languages are spoken.
Good Luck
