Betting on the continued growth of international travel, Singapore Airlines ordered 60 new jets in a deal worth $17 billion, the airline announced.
The airline has split its order, calling for 30 Boeing planes and 30 Airbus jets, with delivery of the aircraft beginning in 2016.
The order is the latest example of an industry investing big in the future.
In 2011, American Airlines ordered 460 new planes and confirmed the order several months later after its parent company AMR Corp. filed for bankruptcy.
Meanwhile, several airlines have recently invested millions of dollars in renovating their lounges and planes to accommodate big-spending fliers, such as business travelers.
