Global curbs imposed to stem the spread of the coronavirus have led to a turbulence in air travel, placing the future of many airline companies in doubt.

James Brown appeared Saturday at Westminster Magistrates Court, where his lawyer pleaded not guilty to the charge on his behalf.

At airports around the world travelers scoured mobile phones or quizzed officials for travel updates as they waited in long queues beneath flight boards showing flights delayed or canceled.

The airline has cancelled almost all its flights for 48 hours due to a strike by pilots over pay.

In a statement Monday, the airline said it had “no way of predicting how many (pilots) would come to work or which aircraft they are qualified to fly.”

British Airways attributed its cancellations to what it called its constant review of security arrangements at all airports, calling them "a precaution to allow for further assessment."

When asked for more details about why flights had been suspended and what security arrangements the airline was reviewing, a spokeswoman for British Airways responded: "We never discuss matters of security."

The scam saw customers diverted to a fake website where credit card details were harvested by the attackers.

The British Airways plane followed the wrong flight plan and ended up in Edinburgh, Scotland, rather than Dusseldorf, Germany.

A British Airways flight with 209 people on board was forced to make an emergency landing in St. John's, N.L., early Tuesday morning after its crew detected heat in a cargo hold.
