hi
i've done a good deal of flying around with my a-100. the only problem i
ever really had was in beirut when i was leaving the country. they
wanted to me to unmount all the modules! (i could talk them out of this
after a long while, though...).
in europe some planes are too small to fit the a-100 in the overhead
bin. i sometimes then have to check it in below as a kind of over-size
hand luggage. but so far nothing has been damaged.
on most international flights the a-100 usually fits in the overhead bin.
in my experience most airport security personnel can somehow discern
that the a-100 has something to do with making sound.
i hope this helps.
with best regards
