Global long-term spending on private jets is starting to slow for the first time since 2009 as slumping commodity prices sap demand in emerging markets, according to an industry forecast.

Deliveries for the 11 years ending in 2025 will be valued at $270 billion, Honeywell International Inc. said Sunday in its annual survey of the luxury-aircraft market. That's down 3.6 percent from last year's comparable projection, and snapped a streak of gains since the last U.S. recession ended.

The decline reflects weakness in Brazil, Russia, India and China, the group known as the BRIC countries, and the impact of political conflicts in the Middle East and Africa, according to Brian Sill, chief of Honeywell's business and general aviation unit. Delays in some new plane models are also pushing back demand, he said.
