Just like Vanilla Air, this airline will extort money from you in fees. This helps them make the money back from lower fare costs. We paid for a 20kg limit checked bag included with our ticket. We had to pay nearly 2800 yen for our checked bag being 1.8kg over that limit. This was literally the cost of an entirely new overweight checked bag. Rather than charge us a certain rate like 500 yen per 1kg over or something. The staff was also unhelpful, didn't explain anything, and English was bad. Screw this airline and the rest of these Japanese LCCs. They all charge ridiculous fees to make up for their "cheap" airfares.
