The Equality Act 2010 gives women (and men) a right to equal pay for equal work.
The roles of flight crew and cabin crew are completely different. They are not compared to each other and are not lumped together to calculate a gender pay gap. The Act requires all companies over 250 employees to publish data. In the case of airlines they will be required to show if there is a gap for pilots and cabin crew separately from each other. It is not a single figure per employer.
I was not supporting positive discrimination. I thought I had made that clear. But there is something wrong when huge parts of the population are debarred from a career because of the cost of entry.
