Deliveries of Boeing 787 Dreamliners have resumed after battery problems led to a worldwide grounding of 50 aircraft.

Boeing has delivered a modified aircraft to launch customer All Nippon Airways, which will restart Dreamliner flights on June 1.

The manufacturer said yesterday that it expected to achieve its target of delivering more than 60 Dreamliners this year.

Thomson Airways and British Airways are among carriers due to take delayed deliveries of the new generation aircraft within the next few months.

Ethiopian Airlines was the first to restart commercial flights on April 27. Other airlines will begin services later in May or in June.

Regulators halted all Dreamliners after ANA and Japan Airlines had incidents when batteries overheated.

Boeing has since modified the aircaft with new batteries.
