Airline: Koreania (I couldn't come up with a good korean name)
Country of origin: South Korea
Aircraft (maximum 2): 777-300ER and 787-9 (GE)
Colours: Mostly White with equal parts red and blue
Airline type (Cargo, LCC, Legacy etc.) Flag Carrier
Logo (example Qatar Airways’ oryx): I was thinking a Taegeuk logo but I think that makes it too similar to Korean Airlines IRL, so you decide.
Any other notes: It should follow East Asian design principles and represent Korean culture since it's a flag carrier.
