China's Guangzhou Baiyun International Airport has introduced three women-only security lanes at its terminals.

Telegraph reports, these lanes were launched for female passengers who are uneasy with male security personnel. In general, it is also to help with long queues since women carry more items to board planes.

"Women passengers usually bring more articles to board planes, and we usually remind them to prepare in advance for security checks for their articles, including cosmetics, mobile phones, iPads and their personal belongings, to help save time," one of the female security guards, told China Daily.

In addition, "Women usually need more time to get through security in airports, therefore opening such security lanes for women will certainly help the airport operate more smoothly," according to He Ying, an official from All China Women's Federation, who told China Daily.

It is estimated to speed up security checkpoints by up to 15 percent faster. Each lane can take about 150 passengers, while the unisex ones can managed 20 - 30 passengers less.

These lanes are handled by female security guards and children of all gender together with their mothers.

Guangzhou isn't the first airport in China to introduce the gender-specific security lanes. Beijing International Airport was ahead to launch three lanes for their female passengers and it is significantly more efficient, according to Chinese officials.

Meanwhile, Shanghai airport has already male-only line alongside the women-only, as reported by Telegraph.

Earlier this year, a passenger bus specific for women was launched in the city of Zhengzhou, China to lessen incidents of harassment in female passengers.

On the other hand, Germany's Frankfurt Airport built a women-only parking space painted in pink with wider bays, CCTV coverage, and were closer to airports.

This move became controversial but according to German officials, it is mandated by law to provide at least five percent of public parking spaces to women, stated in Telegraph.
