when we flew at the end of April, the lady
in front of me had her check-ins hand searched
and they wouldn't let take her aerosol can.
(check-in or carry-on) However it was a very
large can of hairspray!! I got worried because
I had a small can in my bag but they didn't
hand search mine. I would say if you take
a small can (sample size) it will be ok, but
if a scanner detects a big can you will
probably increase your chance of a hand
search.
