All Nippon Airways (ANA), the biggest customer for Boeing Co's grounded 787 Dreamliner, plans about 100 to 200 round trip test flights in May of its repaired aircraft before carrying passengers again from June, sources said.
They declined to be identified as they are not authorised to speak to the media about the matter.
The test flights are aimed at checking the safety of the aircraft, as well as having about 200 of ANA's Dreamliner pilots get accustomed to flying it again after more than a three-month break, one of the sources said.
