Polish national airline LOT has given Boeing until the end of the year to settle on compensation over faults with its 787 Dreamliners or face court action, the company’s chairman was reported as telling a newspaper on Thursday.

Daily Dziennik Gazeta Prawna quoted Sebastian Mikosz as saying that if the two sides do not settle on compensation, LOT will go to court.

“We are holding negotiations because Boeing is our very important partner and we are ready to take any steps possible within the bounds of the law to defend the interests of the company,” Mikosz said.

Earlier this week LOT said it had had to delay some of its 787 flights after checks showed two planes lacked fuel filters and would add the cost of temporary replacement aircraft rentals to its list of compensation claims which were already estimated at PLN100 million zlotys (USD$32 million).
