Sex-listing requirements in even domestic airline records for passengers is a product of the TSA demands. The way airlines have that is restricted to male or female selections, a binary selection that is unnatural given nature produces people who are intersex.
The ICAO standards for travel documents (passports, visas, and national ID cards) have long allowed for M, F or X to be used in the sex/gender field (where X = unspecified). The problem is that the various border management systems in place around the world may or may not accept such a passport.
