Polish flag-carrier LOT expects delivery of its first two Boeing 787s by 30 November, but will not receive its initial complement of five until February 2013.
The airline gave the delivery update as it presented its full-year financial results for 2011.
Last year LOT had been hoping to take its first 787 in April 2012, and to introduce five of the type this year. But it subsequently admitted that the handover would be pushed back to the second half of the year.
Chief executive Marcin Pirog said today that two more 787s would be delivered to LOT in 2014 and the final one would arrive in mid-2015.
LOT had been originally due to take the type in 2008, having ordered the aircraft in 2005. The twinjets will be powered by Rolls-Royce Trent 1000 engines.
