Hello everyone and welcome! First of all I would love to thank the game developers work for their hard and continuous work on making Infinite Flight a better sim! Currently in Infinite Flight we only have the B777-300ER livery for Kuwait Airways. The A321neo is new and is expected to mostly be used for the medium haul flights. Therefore, adding this will open door to many routes!

Kuwait Airways is expected to operate their A321neo to lots of destinations in the Middle East, Northern Africa, the Sub-Indian Continent, and Europe!
