Singapore Airlines saw second-quarter net profits soar by 77% to SG$160 million (£80.5m) as passenger numbers rose by 5%.
However, the airline said yields declined in the three month period to September 30 despite revenue growth of SG$107 million (£54m).
SIA confirmed that a non-stop service to Los Angeles ceased last month and flights to Newark from Singapore will terminate after November 23.
“The group continuously reviews its network to better match capacity to demand, and capacity adjustments to weaker markets will be implemented during the traditional lull in October/November,” the airline said.
Looking forward, SIA said: “The operating landscape for the airline industry remains challenging amid continued global economic uncertainty.
“Advance bookings for the coming months are projected to be higher compared to the same period last year on the back of efforts to boost loads.
“However, ongoing promotional activities necessitated by intense competition and a strong Singapore dollar are expected to place pressure on yields.
“On the cost side, fuel prices are likely to remain high and volatile. Against this challenging backdrop, the group’s financial condition remains strong.”
