Airbus confirmed that German airline Germania has ordered 25 A320neo planes, a transaction worth £2.68bn. Germania has also taken out an option on buying a further 15 of the aircraft.
The US defence firm is to sell 10 LM-100J commercial freighter aircraft to Brazilian logistics group Bravo Industries. The two companies gave no financial details of the contract.
Qatar Airways has agreed to buy up to 10 per cent of Latin America's largest airline, Latam, in a deal worth $613m, subject to shareholder approval. The acquisition follows Qatar Airway's move to increase its stake in British Airways owner IAG in May. The Qatar airline may also be set to take on a significant stake in Italy's Meridiana airline.
In addition, Rolls-Royce chief executive Warren East told reporters at the event that the company could make cost savings of up to £1bn - but that no hard targets have been set. East added that he was looking at new opportunities, including a new Boeing plane. "We would like to participate if it's a sensible opportunity. We will see what plane they actually come up with, if they come up with one," East said.
