US Customs and Border Protection implemented a rule this week that will require airlines to disregard X" sex markers on passports and input an M" or F" marker instead, sending those people with an X" marker into panic.

X" markers became available to US passport holders in 2022, in an effort to allow people with gender identities other than male and female to obtain more accurate travel documents.
