It is mostly a man's world out there in aviation, but the airlines are trying to change that by discrimination in hiring. For any flying job, the typical airline will hire the best of the men who apply. Before they do that, however, they hire any woman who has the minimum certificates and hours. A woman should be able to advance through this career roughly five years faster than a man with the same ability. Some very desirable employers will only hire ex-military pilots unless you happen to be a woman, in which case they will hire you if you meet their bare minimum qualifications.
Note that being a woman is only helpful when moving from job to job. At any given airline, promotion is based on seniority rather than skill or personal characteristics.
