The four other demands are a retraction of the word "riot" to describe rallies, the release of all detained demonstrators, an independent inquiry into perceived police brutality and the right for Hong Kong people to choose their own leaders.
Besides, the reconstruction of the airport's air mail center to enhance its efficiency and capacity is under active consideration and study, while the third runway project is being carried out in full swing, Chan said.
Protesters set fire to a barricade during a protest in Hong Kong on Sunday.
Protesters rounded on a man believed to have opposed them when they had damaged the Chinese flag.
The flag was put into a trash cart and the cart was thrown into a pond at Sha Tin Park, before it was taken out and thrown into the Shing Mun River. They jumped up to smash overhead surveillance cameras, used hammers to knock ticket sensors off gates and spray-painted and broke the screens of ticket machines, using umbrellas to shield their identities.
Carrie Lam, Hong Kong's deeply unpopular chief executive, withdrew the bill earlier this month, but by then the scope of the protests had broadened dramatically and became more focused on Beijing's tightening hold on Hong Kong, as well as the use of force by police.
However, the focus of the protest was in Sha Tin's New Town Plaza, a shopping mall, which was occupied by thousands of protesters on Sunday.
On Saturday police used tear gas and rubber bullets to disperse hardcore activists throwing rocks and petrol bombs in two towns near the border with mainland China.
Protesters then built a barricade across a street near the mall, piled what appeared to be brown palm fronds on top and set them on fire.
Transit authorities closed the two stations on the airport express train to guard against a possible disruption of transportation to the transportation hub.
The protests generally begin peacefully, but often degenerate into confrontations that hard-line protesters say is needed to get the government's attention.
A proposed bill that would have allowed some Hong Kong criminal suspects to be extradited to mainland China for trial sparked the months-long, anti-government demonstrations.
Officials preemptively reduced rail and bus service to the airport in an attempt to stop large numbers of protesters from making it to the airport to carry out their "stress test".
Photographs of petrol bombs and street clashes broadcast worldwide are presenting a huge headache for Beijing, just days before the 70th anniversary of the founding of the People's Republic of China on Oct 1.
The Hong Kong govt has already called off a mountainous fireworks display to impress the day in case of extra clashes.
Hong Kong joined China in 1997 in an agreement made with the British government.
Passengers were advised to leave sufficient time to reach the airport and people on the train were told via onboard announcements that it would make fewer stops than usual, with no mention of the protests.
