Qatar Airways will place an aircraft order at next month's Dubai air show but chief executive Akbar Al Baker refuses to be drawn on any further details.
Speaking during today's Oneworld accession in Doha, Al Baker said: "We will place an order, but of what sort I am not saying."
Qatar is a customer for several Airbus and Boeing types but has also shown interest in the Bombardier CSeries, which has started test flights.
The carrier is already set to take delivery of its first A350 and A380 next year and Al Baker expects delivery of the former - for which it is launch customer - to be on time for the second half of next year.
"We are confident the A350 will be delivered in the second half of 2014. I think [Airbus] will surely deliver to us during this period," he says.
Indications from an Airbus presentation earlier this month suggested a delivery date after August 2014 for the first A350-900 to Qatar, but Airbus has not committed to a firm delivery schedule.
Qatar is also set to take its first A380 - one of the first with modified wing rib bracket design, and the higher gross weight version - in April. The airline has 10 firm and three options on the A380.
