Thats the way Butch is doing it everytime he travells.
I travel quite a lot with my dj box using airlines, maybe six times a year or so and never ever had problems with a 300 count box up until last year. Similar to what happenend to Steve G...since then I only travel with a 100 count box (once bought at Beatin Rhythm) and it fits all size and weight limits. Does limit you indeed a bit in what to bring but on the other hand, how often you carry the same old say 100 + reocrds with you that you just never ever play or just dont wanna play but still carry them with you for that one "just in case" moment ? Limitation is a bonus for the quality..see it that way
NB
and indeed...ryan air should be a total NO GO...unless you fancy sitting on dirty seats and toilets, love to pay for any extra, being treated like cattle and being "entertained" on board by Borats sisters
...acetates no problem by the way..
