On Tuesday, Hong Kong Airport struggled to reopen after cancelling more than 300 flights on Monday following protest that brought the airport to a standstill.

On Tuesday morning, stranded passengers were seen lining up to catch their delayed flights, as airport authorities announced that it will implement rescheduling while blaming demonstrators for the disruption at one of the world’s busiest airports.

With a short warning, airport authorities cancelled all outgoing flights on Monday afternoon, as thousands of protesters started to gather in the departure and arrival areas of the airport.

Passengers with luggage were being checked in for flights, and only a handful of the thousands of protesters who flooded into the airport a day earlier remained in the building.

The flight status board at the departures hall showed several flights listed as “boarding soon” with new take-off times listed for others.

However, the South China Morning Post reported that as many as 160 outbound and 150 inbound flights were already cancelled for the rest of the day on Tuesday.

A traveller from South Africa, Kerry Dickinson, said she doubts if she will ever fly to Hong Kong again after experiencing the delays.

“I’m trying for the third time to get out of here. So yeah, it’s a bit rough when your luggage is (on) one side and you’re (on) one side. No, it hasn’t been funny,” she told the Associated Press news agency.

Another traveller, Kristina Kralikova, blamed the airline for failing to inform passengers that the flights have either been cancelled or delayed.

“My flight was after midnight and everywhere on the website it was like ‘the flight is still on’. So, I came to the airport and it was cancelled and I’m still waiting, like seven hours.”

The airport protest, which caused the cancellation of more than 150 flights, was a rare case of the movement having a direct impact on business travel and tourism – mainstays of Hong Kong’s economy.

Many protesters said on Monday that they were angered by Sunday’s police crackdown, which injured several people and at least one female medic was blinded in one eye.

Police officers were seen firing tear gas at protesters inside a train station, while beating some with their batons.

There have also been allegations of authorities impersonating protesters and trying to stir up violence to draw the attention of the riot police.

As this developed, China has ratcheted up its rhetoric, accusing demonstrators of “wantonly” trampling on Hong Kong’s rule of law and social order.

“Hong Kong’s radical demonstrators have repeatedly used extremely dangerous tools to attack police officers, which already constitutes a serious violent crime, and also shows the first signs of terrorism emerging,” Yang Guang, spokesman for the Hong Kong and Macao Affairs Office of the State Council, said at a press briefing in Beijing on Monday.

Some Hong Kong legal experts say official descriptions of some protesters’ actions as “terrorism” could lead to the use of extensive anti-terror laws and powers against them.

Yang did not suggest that the Chinese government has any imminent plans to step in, but later on Monday, two state media outlets – the nationalistic tabloid Global Times and the People’s Daily – published a video of armoured personnel carriers purportedly driving towards Shenzhen, a city bordering the semi-autonomous territory.

The People’s Armed Police (PAP) are in charge of “handling riots, turmoil, seriously violent, criminal activities, terrorist attacks and other societal security incidents”, the People’s Daily said in the text accompanying the video.

Hong Kong has witnessed 10 weeks of mass anti-government protests that were sparked by a now-shelved extradition bill which would allow criminal suspects to be extradited to mainland China.

The demonstrations have since expanded into wider demands for democratic reforms, a call for Chief Executive Carrie Lam to resign and an independent inquiry into police conduct during the demonstrations.
