weight and height requirement

Hi! I am an aspiring flight attendant but i’m still getting my college degree so I have many years left to apply for the job. Regarding on the my weight should be proportionate to my height requirement, do I have chance if i’m leaning on the skinny side? and i am not talking about normal skinny, I am underweight. I’m 18 years old, 158 cm and I keep on wondering if I have the chance to keep pursuing my dreams.
