The decision is a blow to Poland's national carrier, which is cutting costs in an effort to survive. LOT is Europe's first airline to have Dreamliners, which it hoped would improve its financial results and position.
Their grounding means that LOT will need to extend a lease on three Boeings 767s it currently uses and seek to lease two more for the summer season, spokesman Marek Klucinski told The Associated Press.He added LOT is also talking to Boeing about the costs generated by the idling.
One of LOT's Dreamliners remains in Chicago, one in Warsaw. Both are safe to fly, Klucinski said.
Boeing suspended delivery of three more planned for LOT this year.
