I usually get there 1.5-2 hours before my flight, but I check the TSA average wait times and keep an eye on the news in case I need to leave earlier. I hate to say it, but for my last flight to Orlando, I got to the airport about 40 minutes before my flight due to a combination of waking up 20 minutes late, asking my chronically late brother for a ride to the airport, and some unexpected road construction. It all added up to a big, late mess. Not only did I get there after the cutoff for curbside check in, thus ensuring that I had to wait in line to check my bag, but I ended up spending the entire fifteen minute wait in security looking at my watch and fretting that I'd miss my flight. I got to my gate as they were announcing boarding. Never again! One and a half hours is my absolute minimum and two hours is my ideal.
