A LOT Polish Airlines Boeing 787-8, registration SP-LRA performing flight LO-98 from Seoul (South Korea) to Warsaw (Poland) with 180 people on board, was descending towards Warsaw when the crew noticed a burning odour on board and requested emergency services on stand by for landing. The crew subsequently declared Mayday and continued for a safe landing on runway 11. After landing a passenger dimmable window showed signs of burning.

The aircraft returned to service about 22 hours after landing.

The Dreamliners' (Boeing 787) passenger windows can be dimmed with the assistance of a gel enclosed between the window panes. An electric current through the gel can be controlled by the passenger.

On Jan 8th 2022 the airline sent following statement to The Aviation Herald:

- During descent cabin crew smelled an odor. Captain performed an inspection and Crew decided to perform standard landing asking for landing priority and assistance. Plane landed safely and Passengers were deboarded using the stairs.

- there was no fire,

- window was INOP and disconnected in BUD (Plane was performing WAW-ICN-BUD-ICN-WAW rotation) and was due to replace after landing in WAW (and it happened), so at any point it couldn't be the source of smell.

- most probable cause was one of low voltage fans in IFE cabinet.
