Singapore Airlines (SIA) carried more passengers and filled a higher proportion of its seats in October, but cautioned that the operating landscape remains competitive.

SIA reported 2.8 percentage points rise in passenger load factor to 80.2 percent in October compared to the same period a year ago.

This was due to stronger passenger demand in all route regions, SIA said in a statement.

Passenger load factor grew for all regions, including South West Pacific and Europe.

"The operating landscape remains challenging and efforts to stabilise yields are ongoing," added Singapore's flag carrier.

Passenger carriage, which is measured by passengers-kilometres, also increased by 4.9 percent in October.

A total of 1.65 million passengers, including those on SilkAir and Scoot, were carried in October, up from 1.58 million in the same month last year.

Strong growth in demand in India, China and Southeast Asia helped to improve passenger load on SilkAir, said SIA.

Shares in Singapore Airlines ended up 0.9 percent to S$10.69 on the Singapore Exchange. The stock has gained about 12 percent over the past one year.
