I just returned from a New England/Canada cruise, from Dorval to JFK. My carry-on was searched twice -- once at the regular security gate and again just before I boarded the aircraft (an American Eagle Saab). My checked bag was also searched, rather thoroughly and cameras to be turned on. I pulled out my passport so often, I thought I would wear it out. They checked everything but the fillings in my teeth.
I disagree with one comment in the previous post, a negative feeling about not seeing security personnel. IMO, the best Security can be the Security you do not see.
I think the "no nail clippers" is overkill, but I have to respect their judgement on this, as there might be a very good reason.
btw: Security on the ship (Holland America Line's "Amsterdam") was just as tight. The attack occurred partway through the cruise, but we still had pre-boarding carry-on searches and metal-detector gates. After the attack, we were allowed back on the ship, during port calls, with the same level of security as if we were boarding an airplane.
Condolences to all; I also suffered a loss on United 175.
