DUBAI, Oct 30 (Reuters) - Saudi Arabia's newest airline

Riyadh Air will start formal talks with planemakers Airbus

and Boeing ( BA ) within two months about an order for

A350-1000 or 777X jets, the carrier's CEO, Tony Douglas, told

Reuters on Wednesday.

"We're probably going to go to the market quite soon to run

a competition for an extra wide-body aircraft. So this story is

nowhere near over yet," Douglas said, pointing to an order of 60

Airbus jets earlier on Wednesday.

Douglas declined to comment on the size of the potential

wide-body jet deal.
