Qantas is close to choosing which plane and engine suppliers will provide its next fleet of aircraft.
Airline boss Alan Joyce is in the US this week talking to manufacturers about the needs of the carrier for the next two decades.
Mr Joyce is discussing plans for more than 100 planes to join the Qantas domestic fleet with Airbus, Boeing, Embraer and engine makers.
The airline boss said the aircraft could improve trip cost and efficiency and reduce carbon emissions by up to 15 per cent.
The planes being considered include the Airbus A320neo range and Boeing 737 MAX range. The group is also considering the smaller Airbus A220 and Embraer E-Jet E2 range.
A decision on suppliers is expected by the end of the year.
All planes part of the deal would be flying by 2034.
Qantas shares on the ASX were down 1.55 per cent to $5.72 at 1144 AEDT amid a wider market downturn.
