U.S. authorities are requiring all U.S. airlines to gather more personal data of the passengers, including full names, dates of birth and genders, officials said.

Airlines operating domestic flights must comply with the new rule early next year and those operating international flights by the end of next year, officials were quoted as saying by the St. Louis Post-Dispatch on Monday.

Currently, passengers in the United States don't have to give their dates of birth or genders to the airlines when buying tickets.

The new rule known as Secure Flight, aims to increase safety and reduce the frequency of misidentifying passengers with those named on suspected terrorist lists, according to Carrie Harmon, a spokeswoman for the Transportation Safety Administration.

Also under the new rule, government agents, rather than airline workers, will be tasked to match travelers against names of suspected terrorists.

While more personal data of the passengers will be collected, civil rights groups acknowledged that the new rule is expected to reduce the chances of passengers being erroneously matched with names on the terror list.
