I have no idea if J2 have always done this - just booked flights for May as the price was good, and figured I'd add the extra's nearer the date of travel so selected no bags - it then offered me buy one get one free bags on both flights - bargain! I'm pretty sure you can add bags afterwards, but thought if I couldn't, then 10kg of hand luggage each would suffice and we'll just buy what we need when we get there. Might be worth a shot if anyone else is booking with them, however, at your own risk just in case you can't book them later on!
