LOT Polish Airlines plans to resume Boeing 787 operations June 5, initially deploying the type on its Warsaw-Chicago service.

“Starting from June 5, the Dreamliners will fly to Chicago and, a little later, to New York, Toronto and Beijing,” LOT said in a statement.

Tickets for flights operated by the twinjet on the Warsaw-Chicago service have been returned to sale, along with “chosen flights” to New York, Toronto and Beijing.

LOT, which was the first European airline to take delivery of the 787, has had one 787 stranded in Chicago and another in Warsaw since Jan. 16 when FAA grounded the aircraft due to lithium-ion battery issues.

It is expecting delivery of its third aircraft, which has been used by Boeing for test flights, in June or July.
