* AirAsia X placed firm order for 10 A350s in 2009
* Airline also has 66 A330neos on order
* AirAsia X talking with Boeing about 787-10 - source (Adds company comment, background on swapping models)
SINGAPORE, April 16 (Reuters) - Malaysia's AirAsia X Bhd has no plans to buy the Airbus SE A350 widebody jet, the airline's co-group CEO said on Monday, despite the airline having 10 of them on order.
"The A350 is not an aircraft we will buy," AirAsia X co-group CEO Tony Fernandes said in a Facebook Live chat from London. "Too expensive. Fares would go up."
AirAsia X, the long-haul arm of AirAsia Bhd, placed a firm order for 10 A350s in June 2009. It later ordered 66 A330neos, an updated version of the A330s it has in its current fleet.
The A350-900 has a longer range but also comes with a higher list price of $317.4 million, compared with the $296.4 million price of the A330-900neo. Airlines typically receive large discounts from the list prices.
Manufacturers sometimes allow airlines to swap models even though they have placed firm orders and paid deposits, meaning AirAsia X might be able to convert the A350 order to other Airbus jets like the A330neo or A320 family.
The AirAsia group is one of Airbus' largest customers, but AirAsia X has also been talking to Boeing Co about buying the rival 787-10 jet, according to a source familiar with the discussions.
A final decision on AirAsia X's future fleet is expected later this year, the source said on condition of anonymity. The 787-10 has a list price of $325.8 million.
A spokeswoman for the AirAsia group said it was unable to comment on the fate of the A350 orders or whether the airline was in talks with Boeing about the 787-10. (Reporting by Jamie Freed in Singapore; Additional reporting by Joseph Sipalan in Kuala Lumpur; Editing by Muralikumar Anantharaman)
