FlyDubai, the lower-cost sister airline to long-haul carrier Emirates, has announced an order for 150 Airbus A321neo aircraft at the Dubai Air Show — an estimated $24 billion purchase that will see the carrier for the first time expand its fleet beyond Boeing.

The cost of your next flight is likely to go up.

The airline Emirates says it will purchase 15 additional Airbus A350-900s worth $6 billion after a spat between it and the European manufacturer went unusually public during this week’s Dubai Air Show.

The president of long-haul carrier Emirates says that an initial public offering of stock in the Dubai-based airline could happen as the city-state tries to boost its local financial market.
