You are looking for this thread:

As a general rule, you will not be able to clear security at T3 without a boarding pass for a flight departing from T3. Some people have reported the occasional exception, so you could always try.
Even if you can get through security, however, the T3 AC has in the past only permitted entry with a boarding pass for a flight departing from T3. Again, some people have reported the occasional exception, so you could always try.
