All women crews
Indian(formerly Indian Airlines) Got its first woman Commander (on the 737) about 20 years ago.
and opertated their first all women crew flight about 15 years back(before Air India had recruited its first woman pilot)
about 10% of the total number of pilots is female(including quite a few Training and Line Captains)
Approx 80% of the Flight Attendants are female.
So the Roster ends up operating all women crews quite often.
