My mom, sister and I just flew today out of MCO today and security was pretty much the same. We didn't notice any tighter measures or extra precautions. I would highly recommend arriving for your flight more than two hours in advance, especially if your flight is scheduled for noon or sometime beyond noon. We had an early flight today, scheduled for 7:40am and arrived at the airport shortly after 5am. I'm glad we did because after 6am or so, security started getting very crowded and our flight was delayed a little because we had to wait for 10 to 12 passengers who got stuck in security. Anyways, an employee gave us the heads up that security was absolutely terrible yesterday and on the 1st of January, so I would recommend getting there as early as possible.
