Yup there are plenty of women commercial airline pilots out there. There are those who fly the cargo arm as well.
The thing is not all those who graduate to become pilots will fly commercial jets ( passenger jets ). Some will be seconded to flying cargos etc....
when you dream of flying, it shouldn't matter what type of aircraft you fly.
Singaporegrrl, I strongly suggest you do give becoming a pilot serious thought. You sound sensible enough and mature for someone your age. You ask the right questions and you give brilliant answers, through what you know and research.
I am very sure if you become an FA, you will absolutely rise to the top within a reasonable ( that means - a short time ). So even if you choose this route to realise your dream of flying....
you will succeed nonetheless.
Of course you won't be limited to flying commercial airlines as an FA. With experience, you could move on to becoming a cabin crew for private airlines/individuals. Flying for VIPs, VVIPs and whole bunch Vs
Same goes for a pilot.
I personally know of 3 ladies who started out as an FA for commercial airlines and now they are assisiting in the running of business organisations. They moved on to become a cabin member of certain elite individuals and proved their mettle, impressed their bosses and was given the opportunity to move up in the company.
.... and one of them is a Singaporean as well.
