Emirates Airline placed an order worth $6 billion for 15 additional Airbus A350-900 jets, part of plans from the state-run airline to bolster its fleet of wide-body planes and serve a range of new markets on long-haul flights amid growing demand for international travel.

The companies announced the order on Thursday at the Dubai Airshow, where Emirates earlier this week ordered 95 wide-body jets from Boeing for $52 billion. The companies didn’t disclose financial details, but buyers typically receive steep discounts in such orders.
