Airline company Cathay Pacific Airways had to issue a profit warning as a result of the protests in Hong Kong's home market.
In September the number of passengers flying with the airline decreased by no less than 7.1 percent.
Cathay speaks of "very challenging" circumstances in Hong Kong and the company expects that this will not change in 2019.
Passengers avoided Hong Kong because of the fierce protests against interference by the Chinese government with Hong Kong.
Although the last few days have been relatively calm, the special administrative region is preparing itself for demonstrations again this weekend.
In August, Cathay Pacific announced a profit of 1.3 billion Hong Kong dollars (154 million euros) in the first half of 2019. At that time, the expectation was that profits would rise in the second half of this year.
