WARSAW, Poland (AP) -- Poland's national airline LOT says its Boeing 787s, which had been grounded for months due to battery problems, will resume flying in June.

Sebastian Mikosz, LOT's chief executive, told the PAP news agency on Tuesday that both of the carrier's 787 will resume commercial flights in early June, following repairs by the maker to their lithium ion batteries.

LOT will approach Boeing in mid-June over compensation for losses it suffered due to the grounding of the planes since January, Mikosz said.

LOT spokesman Marek Klucinski confirmed the report to The Associated Press.

On Friday, United States federal regulators approved Boeing's battery fix, clearing the way for the plane to fly again, although the timing remained uncertain.
