DUBLIN, Jan 14 (Reuters) - Saudi budget airline flyadeal

is putting the finishing touches to a deal to order 10 Airbus

A330neo jets in its first full-blown expansion into

wide-body planes, as the kingdom pursues a surge of spending on

aviation, industry sources said on Tuesday.

The low-cost subsidiary of state carrier Saudia is likely to

unveil the order for the upgraded A330-900 variant in the coming

weeks after comparing it with Boeing's smaller 787-9, and the

first jets are expected to arrive in 2027, the sources said.

Flyadeal and Airbus declined comment.
