Airbus and Boeing announced aircraft orders at the Singapore Airshow that indicated a lull in demand for the big manufacturers after the 2014 show hauled in $32 billion of deals, the Associated Press reports.

Airbus announced an order for six A350-900s, valued at $1.8 billion at list prices from Philippine Airlines. Boeing announced a deal for 12 of its 737 jets with a privately-owned Chinese carrier, valued at $1.3 billion.

Boeing and Airbus executives at the show have voiced confidence that air travel in Asia will continue to grow strongly. They said no Asian airlines had deferred orders already placed.

But some industry experts say the slump in oil prices means airlines will keep their older les-fuel efficient aircraft for longer and buy fewer new jets.
