From my feeling, it is NOT a LCC nor FSC (Full Service Carrier), it is between them. The airfare is NOT so cheap, and the services are OK ( but you have to buy ). At HANEDA, they use bus from terminal to planes, instead of using boarding bridge. It is sometimes troublesome if it is rain. At Nagasaki airport , they use same boarding bridge as FSC uses. The problem is that they stop at KOBE on the way of the flight since KOBE is their HUB airport. Overall it is OK because regular airfare is cheaper than FSC regular airfare, but comparing FSC's discount airfare, they are similar price.
