Fewer than 5 out of every 100 airline pilots in the UK are women.
Now airlines want to encourage more girls to train to fly.
British Airways says it employs 200 women out of 3,500 pilots - that's more than any other UK airline.
But airline companies say there are still far too few female pilots and they're trying to get more women to see being a pilot as a job for them.
It takes 18 months to train as a pilot and costs £100,000.
But schemes are available to help trainees with the cost of their training.
