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 A321-200 livery for Gulf Air. The A321neo is mostly used and the A321 will eventually be retired. Therefore, adding this will open door to many routes!

Gulf operates their A321neo to lots of destinations in the Middle East, Northern Africa, the Sub-Indian Continent, and Europe!
