We are (from California) going to Japan this summer and part of our trip is flying from Tokyo to Fukuoka. I'm researching the air fares, and in some cases flying with a budget airline like Jetstar, Peach, Star Flyer etc. could save us some money, even though not much.

Just wondering if anyone here has experience flying with those airlines and if they are comparable to ANA/JAL domestic. The flight itself will be less than 2 hours, I meant how bad could it be? Even if the saving is only $25-30/person, if the experience is not much different, why not going with the budget airlines.
