Pretty nothing more to say about it - it's the 777 in the Polish Airlines LOT paint scheme, as in use since the 1980s till mid-2010s.
Labeled as fictional, because, although some 777s flew for LOT, I think they were a total lease, crews included, and were not painted in LOT liveries. Closest to this, what LOT had in real life, was the 767-200/300..

Includes a custom interior - upholstery was changed, along with inflight displays, magazines and some stuff in the kitchen was replaced wih Polish products.

Enjoy!
