Just came back yesterday, it took us 10 minutes to check in for Southwest, one bag was 1.5 lbs over the weight limit but they 'just let it go'. Security line took about 5 minutes (this was around 4pm), and that was due to me buying a whole bunch of stuff at the Earport and then having to juggle 2 Disney bags, 2 carryons, 2 children and one stroller. It was a breeze.
