It would be nice if Infinite Flight would add more Japan liveries. For example, my favorite would be this Skymark Airlines and there 737-800 fleets.
Skymark Airlines Inc. is a Japanese low-cost airline headquartered at Haneda Airport in Ōta, Tokyo, Japan. It operates scheduled services with a main base at Haneda Airport, but is also the dominant carrier at Kobe Airport, and the only Japanese airline offering scheduled services at Ibaraki Airport north of Tokyo.
The routes they go to are Amami Island, Fukuoka, Ibaraki, Kagoshima, Kobe, Nagasaki, Nagoya, Okinawa, Sapporo, Sendai, Shimojishima, and Tokyo (NRT and HND).
This would be a good livery on Infinite Flight in my opinion.
